Subsystem Description
OverviewThe Scalar 100 automates the retrieval, storage and control of DLT/SDLT, LTO, or AIT cartridge tapes. Cartridges are mounted and dismounted in tape drives via supporting software from the host without the intervention of an operator.

The Scalar 100 is designed to accommodate the above mentioned media types, although not at the same time. It is NOT a mixed media library. The media and drive type must be specified when the library is ordered.

The Scalar 100 can be configured to accept from one to six Tape Drive Modules. Each Tape Drive Module is a unit which contains a DC power supply, cooling fan, miscellaneous hardware and either one or two tape drives, depending on the drive type:

• DLT/SDLT Tape Drive Module: contains one DLT/SDLT tape drive.

• LTO Tape Drive Module: contains one LTO tape drive.• AIT Tape Drive Module: contains two AIT drives.

Refer to Figure 2-3 on page 12 for a diagram of drive column configurations.

The library total storage capacity varies according to the media type. Three storage columns can each contain three removable magazines. The number of storage slots within each magazine is dependent on the type of magazine:

• DLT/SDLT Magazine: contains five storage slots.• LTO Magazine: contains six storage slots.• AIT Magazine: contains eight storage slots.

The maximum cartridge configuration also includes a mailbox or Import/Export facility. There are two available mailbox configurations:

• The standard mailbox contains one DLT/SDLT or LTO cartridge or two AIT cartridges and is available to all library configurations.

• The optional mailbox contains two magazines (as described above) which can be removed via the Mailbox door and one fixed magazine which can only be removed via the front door.

In addition to the above storage slots, each of the three storage columns has provision for an additional fixed slot located at the top of each column that can be used for storing cleaning or special use cartridges.

The Scalar 100 is offered either as a stand-alone model or as a unit that can be installed in a standard 19 inch rack.

All of the above configurations can be field upgraded to accommodate the maximum drive and storage configurations and a redundant DC power supply. Refer to Optional Features on page 15 for additional information.

Host AttachmentThe Scalar 100 is a SCSI target device supporting communication with a host through fibre or SCSI connections.

Native Fibre ConnectionsA library supporting native fibre attachments communicates with a host through an intermediary LUN-1 (Logical Unit Number) interface in one or more installed drives. In this type of connection, a host is connected directly to a drive rather than a library. Communication is accomplished as a host sends commands to and receives status or responses from one or more LUN-1 enabled drives.

LTO-3 drive modules support native fibre connections. Each drive has a single LC fibre connector located in back of the module for attachments.

SCSI ConnectionsA library supporting SCSI connections can be connected to LTO-1 or LTO-2 drive modules via a SCSI-2 Low Voltage Differential or High Voltage Differential (LTO-1 only) SCSI bus. Both ends of the bus must be terminated. A terminator is shipped with each library. The SCSI LTO-3 drive module is LVD only. The design of the library allows the SCSI type (LVD or HVD) to be configured at the customer site with a switch located on the Library Controller.

Each LTO drive module has two HD-68 connectors for attachments. (When attaching to a 1-byte host, a 1-byte to 2-byte interposer is required.) Although the library can be attached to a wide SCSI bus, it is not a wide SCSI device and its SCSI ID must be in the range of 0 to 7. The default SCSI ID for the library is 0.

Libraries that do not have native fibre connection capabilities can be connected to a Storage Area Network (SAN) via an optional Storage Networking Controller (SNC), where the SNC converts either Fibre Channel protocol or Gigabit Ethernet (GbE) protocol to parallel SCSI protocol.

Functional DescriptionThe Scalar 100 can be installed as a stand-alone unit or in a standard 19-inch rack.

The Scalar 100 configuration must include at least one tape drive. A maximum of six (DLT/SDLT or LTO) or eight (AIT only) drives can be installed (Refer to Table 2-1 on page 6). The Scalar 100 system contains cartridges, library control hardware, tape drives and a robotic system. The tape cartridges are stored in removable magazines that are designed so that tape cartridges can be inserted only in the proper orientation. Once inserted, the tape cartridges stay in the magazine even when it is inverted and lightly shaken. The magazines can be inserted in only one way into the mounting columns in the library. Please note that each type of magazine can only be inserted in its own mounting column. For example, a DLT/SDLT magazine CANNOT be inserted into an AIT or LTO mounting column, and so forth.

The library robotics system moves cartridges between storage slots, tape drives, and the mailbox. A gripper is used to get and put cartridges in a slot or a tape drive. A barcode scanner on the picker identifies the cartridge or slot. The mailbox allows cartridges to be added or removed from the Scalar 100 without interrupting the operation of the library.


March 2005

The cartridge storage slots and picker are accessed by opening the front door of the Scalar 100. The Tape Drive Modules, Power Supplies, Host SCSI Interface PCBA, RMU, and FCR-1 or SNC Module are accessed from the back of the Scalar 100. Maintenance activity is performed by using these areas.

Requests issued from the host result in cartridge movement in the library. The primary requests issued are for mounting and unmounting cartridges in the tape drives and for importing and exporting volumes to or from the library. The host has records of the physical location of a volume in the library. The physical location is also managed by the library. Each volume can have a machine and operator-readable external label to identify a volume in the library during initial inventory and any time a volume is added to the library. The library stores the physical location of the cartridge in an inventory database based on the cartridge volume serial number (volser). All host requests for operations involving movement or use of a volume need only reference the physical location of the volume for the library to perform the request.

In addition to requesting movement of cartridges in the library, the host can obtain status, performance, configuration information, and information about the cartridges stored in the Scalar 100.

Functional UnitsThe Scalar 100 consists of the following functional units:

• Tape drives

• Library control hardware

• Cartridge storage slots

• Robotic system

• Mailbox (Import/Export station)

Tape DrivesThe Scalar 100 currently supports the following tape drives:• DLT/SDLT type drive (DLT 7000, DLT 8000, SDLT 220,

SDLT 320, SDLT 600)• LTO type drive (IBM Ultrium)• AIT type drive (Sony SDX-500C, SDX-510C, SDX-700C)

STATICSENSITIVE

Functional Units 9

10 Introd

All tape drives are packaged in a common drive module that is designed for quick removal and replacement. The Tape Drive Module is a field replaceable unit (FRU) that is sent back to ADIC for repair.

Note: Library Control Path libraries do not support mixing different drive types. This includes different models of the same drive type. Drive Control Path libraries do not support mixing different drive types within the same partition; however, different generations of LTO drives can exist within the same partition.

Library Control HardwareThe library control hardware controls all operations in the Scalar 100, including the interaction between the library and operators. The library firmware creates and maintains the Scalar 100 configuration, the physical location of the robotic system, and the inventory of cartridges. The database is kept in the memory of the library control hardware.

Cartridge StorageThe Scalar 100 contains cartridge storage slots in addition to any tape drives installed.

Storage Slot Numbering: The following convention is used to identify the coordinates of each library element (storage slots or drives).

The columns are numbered 1-5, starting from the mailbox column and going clockwise. The magazines within each storage column (1, 2, 4, 5) are designated A to C from top to bottom, and the rows within each magazine are numbered from top to bottom (1 to 5 for DLT/SDLT, 1 to 6 for LTO, and 1 to 8 for AIT); the slots in the drive column are designated 1 to 6 from bottom to top as shown in Figure 2-2.

Note: The fixed slots in columns 2, 4, and 5 do not have magazine designations and are always numbered 0. Therefore, the coordinate for the fixed slot in column 2 would be “2 - 0” (the “-” indicates no magazine is present). Column 3 can have up to six drive modules. Drive module designations are one through six.

To manipulate the media within the library, the host must reference each movement with source and target designations. This is done via SCSI element addressing, which specifies precisely which slots within the library are to be used. For this purpose, the following addressing scheme will be used for the library.

Robotic SystemThe robotic system identifies and moves cartridges between storage slots, tape drives, and the mailbox. The robotic system has:• A picker assembly for mounting a cartridge gripper and a

barcode scanner.• A cartridge gripper for picking and placing cartridges in

storage slots, tape drives or the mailbox.• A barcode scanner for reading the external labels on the

cartridges. It is used during the inventory process to locate and categorize all cartridges installed in the library. The barcode scanner is also used during the teaching process during which it reads the fiducial labels to identify the types of storage magazines and tape drives installed in the library. Fiducial labels are barcode labels located on tape drives, storage columns and magazines. Each label has a different value to identify various types of tape drives, storage columns and magazines that may be installed in the library.

• A vertical Y-axis drive for moving the picker assembly vertically in the library.

• A rotary axis drive for moving the picker assembly between storage and drive columns.

• A reach axis for moving the grip fingers forward or back.

Mailbox (Import/Export Station)This facility allows the user to insert and eject cartridges without interrupting the normal operation of the library. There are two models of the mailbox:• The standard mailbox has a capacity of one DLT/SDLT,

one LTO cartridge, or two AIT cartridges. The cartridges can be inserted or ejected by opening the mailbox door.

• The optional mailbox has a capacity of 10 DLT/SDLT, 12 LTO, or 16 AIT cartridges contained in two magazines that can be inserted or ejected by opening the mailbox door plus one fixed magazine containing five DLT/SDLT, six LTO, or eight AIT storage slots. This magazine can only be removed via the Library front door like other storage magazines in the Library.

Tape CartridgeThe Scalar 100 automates the retrieval, storage and control of DLT/SDLT, LTO or AIT cartridge tapes. Corresponding tape drives must be installed in the library.

Each tape cartridge in the Scalar 100 must have an external label that is operator and machine readable to identify the volser. The external label can contain up to 13 characters for the volser. The characters can be selected from uppercase A-Z and numerics 0-9.

A separate single character is used to identify the cartridge type. For DLT/SDLT and LTO cartridges, the media identifier is imbedded at the end of the volser label. Any code 39 labels will be supported.

Refer to the Scalar 100 User’s Guide for more information on the types of labels supported by the library.

The external labels on the cartridges identify the cartridges to the Scalar 100. Some software requires that the internal volser be the same as the external label on the physical volume. The following table lists the cartridge type and its identifying character:

Maintenance PlanThe Scalar 100 consists of two hardware subsystems: the library and the tape drives. The tape drives are packaged in a common drive module with each drive module being a FRU. When a drive failure occurs, the drive module is removed and returned to ADIC for repair. The Scalar 100 maintenance package supports the library and the library interfaces with the tape drives.

Maintenance StartStart all maintenance activity for the Scalar 100 and the integrated subsystem using the START section in this manual. A symptom to action table is provided to quickly determine which procedure to use for the reported problem and how to prepare the library for service. Subsystem problem determination information is included to help determine the failing components. For all service calls, the Field Engineer will be directed to the START procedure in this manual.

Functional DiagramThe following diagram shows the major functional areas of the Scalar 100. Table 2-5 on page 18 describes each functional area. For a FRU associated with the functional areas, refer to Table 7-1 on page 85.

Service Action
Codes

OverviewWhen a failure occurs, the Scalar 100 firmware performs error recovery and error reporting. If the failure requires a service call, a two-byte Service Action Code (SAC) is generated and presented on the Operator/CE panel. This Service Action Code is the result of the Scalar 100 firmware analyzing all pertinent information available at the time of failure including sense data, the operation in progress, error and threshold data and any data returned from diagnostic routines invoked by the firmware to isolate the failure.

Retrieving Command and Error LogsPrior to performing the suggested actions for each SAC, it is recommended that you retrieve the Command and Error logs in case you need further assistance from Technical Support to resolve the problem. There are three methods of retrieving these logs:

42 Introd

• The first method to collect the Command and Error logs is accomplished via the Remote Management Unit (RMU). Refer to the Library User’s Guide for procedure on how to perform this task.

• The second method requires a PC running Windows equipped with an RS-232 port and a straight through serial cable (a null modem cable will not work):

• Connect the serial cable from the PC COM port (any COM port will work) to the serial port located on the Host SCSI Interface PCBA as shown in Figure 6-15 on page 79.

• Run HyperTerminal from the PC and configure it using the following data:

• Bits per second: 38400• Data bit: 8• Parity: None• Stop bit: 1• Flow control: None

• From the Operator Panel, send the logs to the HyperTerminal (Main Menu >Status >Logs >Error Log >Print) and (Main Menu >Status >Logs >Command Log >Print).

• The third method is a manual process. It is accomplished via the Operator Panel (Main Menu >Status > Logs then select either >Error Log or >Command Log). Once the logs are displayed, collect as many errors and commands as possible.

Service Action CodesRefer to Table 5-1 on page 43 for the Service Action Codes, associated error descriptions and the actions that can be performed in addition to the FRUs that can be replaced. Each SAC consists of two bytes “nn xx”:

• “nn”: Service Action Code.• “xx”: Service Action Code modifier, this byte identifies

the processor that reports the error:

• “00” = Main Controller• “10” = Picker Controller• “20” = Display Assembly• “3x”= Drive Sled Controller (“x” = Drive ID (1 to 6)).• “40” = SCSI Host Interface Controller• “50” = Remote Management Unit Controller

ReportedSAC

01 xx

02 xx

03 xx

Note: For most SACs, the modifier is extra information thus the value is not important; however a small number of SACs will use this modifier to further refine the actions to be performed. The SACs requiring the modifier value are documented so that the suggested actions are grouped depending on the value of the modifier.

The table also lists the FRU names and a reference column, which points to the page containing the location of the FRU or the procedure on how to perform the suggested action.

Actions associated with each SAC are listed in their order of probability. Always perform the actions in the order listed, starting with the top action and continue down the list until the problem is resolved.

A failure was detected during the scanning of fiducial or cartridge labels. This failure can be caused by a number of things. Perform the following actions to recover from the failure.

This error can be caused by a dirty barcode scanner (dust or fingerprints). Clean the barcode scanner window with a lint free cloth and retry the operation.

This error can be caused by a dirty, damaged, or missing fiducial label on the magazine. To isolate the problem magazine(s), perform one of the following two techniques:• Note the number of magazine installed in the library (each

magazine should have at least one cartridge in it) and use the Operator panel to compare this information with the number of magazines reported by the library. If the library is equipped with a multi-slot mailbox, the icons representing the magazines in the mailbox column appear in the mailbox area.

• Remove one magazine at a time and retry the operation until the problem is gone.

Replace the failing magazine if found.

This error can be caused by dirty, damaged, or incorrect cartridge barcode labels. To isolate the problem cartridge(s), try one of hte following techniques:• Note the number of cartridges installed in the library and

use the Operartor panel to compare this information with the number of cartridges reported by the library.

• Remove a few cartridges at a time and retry the operation until the problem is gone.

Replace the barcode label on the cartridge(s)/

(Main Menu >Status >Library >System or >Slot)

This error can also be caused by hardware failures:• Check to make sure that the Picker Assembly Flex cable

connector is properly seated on the Picker Control PCBA.• Inspect the Pcker Flex Cable for any obvious damage. Rotate

the Picker Assembly to maximum counter clockwise (grip fingers facing the drive column) and inspect the area of the cable loop that is near the Rotarty Motor encoder. If the Picker flex cable does not contain enough slack in this loop, the encoder on the Rotary axis motor can rub on the cable and cause damage. If the Picker Flex Cable is damaged, replace the Picker Assembly.

Communication was previously established between the library and the tape drive but the library detected that communication is no longer present or the drive status is not as expected. Note: The coordinates of the failing tape drive sled is posted on the Operator Panel but if this information was reset by the operator, it can be retrieved by going to the error log and refer to the error modifier “xxxx”, this value will show the failing drive

If the SAC modifier “xx” = “00 “: • Check the firmware on the drive sled and update if

necessary.• Re-seat the drive in question by loosening the two

thumbscrews, remove the drive and re-install it in the same drive slot.

• Check to see if there is a cartridge in the failing tape drive that prevents the drive from becoming ready: Eject the cartridge and retry the operation then replace the Tape Drive Module if appropriate.

• Replace the Power Distribution PCBA.• Replace the cable between the failing Tape Drive Module

and the Power Distribution PCBA.

The Picker Assembly delivered a cartridge to a tape drive but the drive does not confirm tape loading status. The “xx” part of the SAC identifies the drive.

If another tape drive is available, retry the operation by loading the same cartridge in that tape drive:• If the operation failed, inspect the cartridge for damage and

replace it. • If the operation is successful, verify that the original failing

tape drive is failing by loading another cartridge in that tape drive. Replace the tape drive if this operation failed. 90

The firmware (variant) installed on the tape drive is not supported by the library. The “xx” part of the SAC identifies the drive.

Install the correct firmware on the tape drive.

Replace the Tape Drive Module with a certified spare part. 90

Firmware Support ProceduresThere are three ways to update firmware for the Scalar 100. They are described below.

Important Note: The application firmware of all boards (Main, Picker, Display, Drive Sleds) must be updated to the same level. Verify this by using the Operator Panel (Main Menu > More >About >Details).

Using the RMUIf an RMU is installed in this library, refer to the User’s Guide for procedure to update firmware using the RMU.

Using a PCThe following procedures require:

• A PC equipped with an RS-232 port and a straight through serial cable (a null modem cable will not work)

• A 3.5” diskette drive

• Any Windows Operating System

Download the latest firmware level (e.g., v3_02_0002.lif) and an executable file (dowload.exe) from the ADIC web site and store them in a temporary directory in the PC.

Connect the serial cable between the PC and the serial port located on the Host SCSI Interface PCBA or Serial Interface PCBA, the library must be powered ON.

From command prompt, issue the following command, note that the command is case sensitive:

dl -Cn -F /tmp/fn.lif

Where:

dl Firmware Download Command

-Cn Communication Port number n

-F Use the following filename

/tmp/fn.lif Filename (e.g., v3_02_0002.lif)and location

You can also download code to individual PCBAs (Main Controller, Picker Controller, Display Controller, Drive Module Controller) by adding the following controls:


March 2005

-M Download Main Controller PCBA

-P Download Picker Controller PCBA

-D Download Display Controller PCBA

-S Drive Module (must specify Module number)

An example follows:

To download code to Picker Controller, Drive Module 3 and Drive Module 5 using communication port 2:

dl -C2 -F /tmp/v5_14_0001.lif -P -S3 -S5

Using the Customer SCSI Host Initiator

The following procedure requires the customer’s SCSI host initiator. Refer to Figure 7-15 for locations of components.

Note: This function is only available with Library Firmware level 2.00 or higher. It is assumed that the host system had recognized the library and a device driver is available to communicate with the library.

The firmware can be downloaded into the library using the SCSI “Write Buffer Command” from the SCSI Host Initiator. Download the latest firmware level (e.g., v3_32_0002.lif) from the ADIC web site and store it in a temporary directory in the host initiator. This firmware file contains application images for all library components (i.e., Main, Display, Picker, Drive, etc.).

The buffer ID of the firmware is 0, and the mode is 5 (download firmware and save). The firmware can be downloaded all in one command, or broken down into segments. If it is segmented, the segments must be sent in order from lowest address to highest, and must be contiguous. The last segment sent (or the only segment, if it is sent all at once) must have a time-out no shorter than two minutes.

You must first prepare the Scalar 100 Library to receive the new firmware by using the Operator Panel (Main Menu >More >Service >Library >Firmware Update). Note that if the Write Buffer Command is not initiated within 10 minutes from executing the above Operator Panel sequence, the function will be aborted and the Library will return to normal operation.

For example, to download in one piece, use the following CDB (in hexadecimal):

Firmware Support Procedures 163

164 Introd

3b 05 00 00 00 00 0D C4 00 00

Where:

3b Op code for Write Buffer Command

05 LUN = 0, Mode = 5

00 buffer ID = 0

00 00 00 buffer offset = 0 (start from the beginning)

0D C4 00 parameter list: 881 KB is the size of the data to download

00 control bits (always zero)

The data associated with this Write Buffer Command should be the entire firmware file. You must first convert the file into decimal, in this case 881 KB or 902,144 decimal bytes (881 x 1024), then convert this number into hexadecimal (902,144 = 0x0DC400).

As another example, to download the firmware file size of 881 KB in segments of 64 KB pieces, use the following 14 CDBs (all values are in hexadecimal):

CDB: 3b 05 00 00 00 00 01 00 00 00 (0x10000 bytes starting at 0x000000)










CDB: 3b 05 00 0A 00 00 01 00 00 00 (0x10000 bytes starting at 0x0A0000)

CDB: 3b 05 00 0B 00 00 01 00 00 00 (0x10000 bytes starting at 0x0B0000)

CDB: 3b 05 00 0C 00 00 01 00 00 00 (0x10000 bytes starting at 0x0C0000)

CDB: 3b 05 00 0D 00 00 00 C4 00 00 (0xC400 bytes starting at 0x0D0000)

The data for each of the first 13 Write Buffer commands should be the sequential 64 KB pieces of the firmware file (64 x 1024 = 65,536 decimal = 0x010000) for a total of 832 KB.


March 2005

The data for the last Write Buffer command is the remaining 49 KB (881 KB - 832 KB) of data (49 x 1024 = 50,176 decimal = 0xC400).

AC and DC PowerThe Scalar 100 Library contains an AC Input Power Module that requires 110V to 230V, 10 Amperes single phase AC power. The AC Input Power Module supplies AC to the DC Power Supplies as well as to all Tape Drive Modules in the library.

Standard Scalar 100 configuration requires one DC Power Supply, an optional DC Power Supply can be installed to provide DC power redundancy. When two DC Power Supplies are installed, their outputs are connected together and each is operating at half its duty cycle. The DC Power Supplies are auto-ranging and can accept 110 to 230 VAC.

Each Drive Module has a built-in DC power supply and only requires AC input. This DC Power Supply is also auto-ranging and can accept 110 to 230 VAC.

Figure 8-1 on page 188 shows the locations of the AC Input Power Module and the DC Power Supplies in the Scalar 100 Library.

Figure 8-1 AC Power Module and DC Power Supplies Locations

AC and DC Power DistributionThe AC Input Power Module distributes AC to all Tape Drive Modules and the DC Power Supplies via the Power Distribution PCBA. The output of the AC Input Power Module is controlled by a Switch and protected by two 5A fuses. Note that there is also a Power On/Off Switch on the library front cover, this switch must also be in the On position to power up the library. The DC Power Supplies and all Tape Drive Modules are plugged into the Power Distribution PCBA via self-docking or blind-mate connectors.

Each DC Power Supply has a built-in switch which is activated as the DC Power Supply is plugged into the Power Distribution PCBA. AC voltage is immediately available to the DC Power Supply as soon as the connection is made.

There are two versions of the DC Power Supplies with each requires a corresponding Power Distribution PCBA to operate. Physically, these two types of DC Power supplies look the same, you need to order the correct one for your library. The library will not power up if the DC power supply and the Power Distribution PCBA are not compatible:

• Type I DC power supply provides +5VDC and +12VDC to the Power Distribution PCBA to be distributed throughout the Library. This DC Power Supply is used in older libraries.

• Type II DC power supply only provides +12VDC to its associated Power Distribution PCBA. The Power Distribution PCBA generates +5VDC from the +12VDC and distributes these two voltages throughout the Library. This DC Power Supply is used in newer libraries to handle additional appliances such as the Storage Networking Controller (SNC) Module.

When two DC Power Supplies are installed in the Scalar 100 Library, their outputs are connected together. If one of these DC Power Supply fails, the library can still operate normally. Each DC Power Supply also has an LED indicator in the back to indicate its status: Green indicates the Power Supply is operating normally and Red indicates a failure that requires a replacement. The Operator/CE panel will present a message when this condition occurs. The failing DC power supply can be removed and replaced without interrupting the library’s operations.

As each Tape Drive Module is plugged into the Power Distribution PCBA, its Drive Communication PCBA receives +5VDC power from the Power Distribution PCBA. Firmware on the Drive Communication PCBA attempts to communicate with the Scalar 100 firmware. Once this communication is established, the Scalar 100 firmware will activate a relay that provides AC power to the Tape Drive Module. Options are provided through the Operator Panel menus to remove and restore AC power to the Tape Drive Module during a service call.

Use the following diagrams for AC and DC power distribution within Scalar 100:

• Figure 8-2 on page 190 illustrates AC and DC power distribution for Type I DC Power Supply. Note that each DC Power Supply generates +5VDC and +12VDC.

• Figure 8-3 on page 191 illustrates AC and DC power distribution for Type II DC Power Supply. Note that each DC Power Supply now only generates +12VDC and there is a DC to DC converter on the Power Distribution PCBA that generates +5VDC from the +12VDC.

Installation
OverviewThis chapter contains step by step procedures for installing all models of the Scalar 100 and optional features.

Installation

Pre-InstallationThe Scalar 100 can be installed in a rack or as a stand-alone model. The library ships standard as a stand-alone configuration so a rackmount kit is required for rackmounting the library.

Parts required for installation are shipped with each library. When unpacking the library and removing the packing material, do not lose or misplace any enclosed parts.

Two door keys shipped with each library are used to lock and unlock the front door.

Step 1 Familiarize yourself with these instructions before proceeding with the installation tasks.

Step 2 Understand the customers’ requirements for connecting cables between the host and the Scalar 100 and all tape drives.

Special ToolsNo special tools are required to install the Scalar 100. A standard CE tool kit is all you need to install the library.

198 Introd

UnpackingUse the instructions supplied with the Scalar 100 to unpackhe library. When you remove the packing material from the palette, put the parts in a safe area so they will not get damaged.

Step 1 Move the library in place. If it will be installed on a raised floor, ensure the hole cut-out is placed under the rear of the frame.

Step 2 Locate the keys, which are taped or tied to the back of the frame. Open the front door using the key.

Step 3 Remove the restrainer that secures the Picker Assembly in place.

Step 4 Keep all the parts in a safe place to keep them from being damaged.

Start InstallationUse the following table to start your installation.

The doclosedperforstep.

Installing a Stand-alone LibraryRefer to Figure 10-1 on page 200

Tools required: Large flat blade screwdriver or 3/8 nut driver and Phillips screwdriver.

Step 1 If the Scalar 100 is installed on a raised floor, have the customer supply you with a floor cut-out.

Step 2 Position the Scalar 100 in place.

Step 3 If there are casters to be installed on this library, perform the following steps:

Tip: The best way to perform the following steps is to place the Scalar 100 on a surface that allows access to four corners of the library where the components on the bottom of the chassis are accessible. The Scalar 100 can be laid onto its side for this procedure and the sling shipped with the library can be used to tip the Library onto its side.

a. Remove the four rubber feet on the bottom of the library. Each foot is attached to the frame with a Phillips screw.

b. Each caster is attached to the Scalar 100 with four bolts. Always install the two fixed casters on the back of the machine and the two swivel casters on the front. After installing the casters, lock the two front casters in place.

Step 4 Open the door and move the Picker Assembly along its vertical axis to ensure that all packing material was removed and no binds exist. Important: Do not move the Picker Assembly along the rotary axis by hand as it will be damaged. The Picker Assembly can be rotated by turning the gear on the Rotary Motor by hand.

Step 5 If you have other library features to install, go to Start Installation on page 198 to find the correct procedure, otherwise go to Cables from Hosts on page 220.

Installing Scalar 100 in a RackRefer to Figure 10-2 on page 203, Figure 10-3 on page 204 and Figure 10-4 on page 205.

You must have the rack mount hardware kit (P/N 93-0805-02) available before proceeding.

Special care should be taken when installing a Scalar 100 into a rack. Heed the following guidelines:

• For continued safe operation, the recommended maximum internal ambient temperature of the rack should not exceed 40° C.

• While installing a rack mounted unit, do not block or otherwise restrict airflow to the power supply front or rear vents.

• To maintain rack stability and the unlikelihood of tipping, consider the mechanical loading of the rack to ensure a low center of gravity.

• Before installing a unit into a rack, consider the overall loading of the branch circuit supplying power to the rack.

Since this unit is intended to be attached to an earth ground, ensure that a reliable path to earth ground is maintained within the rack.

Tools required: Phillips screwdriver, 3/8 nut driver and T20 Torx driver.

Step 1 The Scalar 100 requires 14U space in a standard 19 inch rack, make sure this space is available and allocated in the rack (each U is 1.75 inch or 4.45 cm and it’s usually denoted by three holes in the rack). Measure the required space and mark the holes you are planning to use to make the subsequent steps easier.

Step 2 Install the rear rack mount hardware by attaching the sheet metal to the rear rack using the parts shown in Figure 10-2 on page 203.

Step 3 Install the front rack mount hardware by attaching the sheet metal to the front rack as shown inFigure 10-3 on page 204.

Step 4 Attach the front rack mount hardware to the rear rack mount hardware using screws through the slots as shown in Figure 10-3 on page 204.

Step 5 Complete the rack mount hardware installation by attaching the rear bracket to the rack mount hardware as shown in Figure 10-4 on page 205.

Step 6 If there are Tape Drive Modules installed in the Scalar 100, remove all module(s) or storage module(s) and DC Power Supplies from the library to reduce its weight. Each of these items can be easily removed by loosening the two captive thumbscrews and slide the item out of the chassis.

Even with the above components removed, the Scalar 100 weighs in excess of 150 lbs (65 kgs) and requires two persons to properly lift and position it in a rack.

Note: Up to three Scalar 100’s can be rackmounted in a standard 42U rack.

Step 7 Remove the four rubber feet on the bottom of the library as shown in Figure 10-1 on page 200.

Step 8 Remove both side covers from the Scalar 100. Each cover is attached to the chassis with four Phillips screws as shown in Figure 10-5 on page 206. After removing the Torx screws, the covers can be removed only if the front door is opened.

Step 9 From the front of the rack, use the handles provided on both sides of the Scalar 100, lift and position the library onto the rack mount hardware.

Step 10 Slide the Scalar 100 onto the rack mount hardware until it stops against the rear bracket. Attach the Scalar 100 to the rear bracket with two Phillips screws. This ensures that the Library is secured to the rack and properly grounded.

Step 11 If you have other library features to be installed, go to Start Installation on page 198 to find the correct procedure. Otherwise go to Cables from Hosts on page 220.

Cables from HostsThe Scalar 100 is a SCSI target device supporting communication with a host through fibre or SCSI connections.

The Scalar 100 supports SCSI-2 High Voltage Differential (HVD), Low Voltage Differential and Single Ended (LVD/SE) attachments via a SCSI-2 P cable with 68-pin D-connector. The Differential is a fast and wide 2-byte SCSI-2 attachment. When attaching to a 1-byte host, a 1-byte to 2-byte interposer is required. The SCSI type can be selected using a switch located on the Host SCSI Interface PCBA as shown in Figure 6-15 on page 79.

The Scalar 100 is configured with one SCSI adapter, the adapter is connected to a SCSI bus and this bus must be properly terminated with the terminator shipped with each library. Since the Scalar 100 only logically supports the one-byte wide protocol, the library SCSI ID value must be within the range of 0-7.

Important Note: Set the switch to match the SCSI bus that the Scalar 100 is connected to (HVD or LVD/SE). Connect only the SCSI cables and terminator to the side of the SCSI PCBA that is selected. Do not leave any cables or terminator connected to the INACTIVE side.

Terminator power is provided via a jumper on the Host SCSI Interface PCBA. Refer to Figure 6-15 on page 79 for locations of the Term Power jumpers.

Important Note: The factory will have both jumpers installed to provide term power as the default setting. The customer will decide which device on the bus needs to provide term power. Request this information from the customer and remove the jumper from the selected SCSI side if term power is not needed in this Scalar 100.

Host to Tape DriveAttach host cable to the tape drive(s) according to customer’s configuration. An example of SCSI cable connections from the host system to the library and tape drives appear in Figure 10-15 on page 221.

Figure 10-15 SCSI Cable Connections

Host to Library

Step 1 Route the cable from the host to the back of the Scalar 100 Library.

Step 2 Connect the cable straight into the selected SCSI connector on the Host SCSI Interface PCBA (HVD or LVD/SE).

Step 3 If this is the last device on the SCSI bus, install the terminator P/N 61-1140-01 (HVD) or P/N 61-3020-02 (LVD/SE) on the other connector of the SCSI PCBA.

Step 4 If attaching to the next device in the chain, install the next cable into the other connector of the Host SCSI Interface PCBA.

Voltage CheckStep 1 If the customer outlet case is conductive (metal),

measure for 0 V AC from building ground to the outlet case.

Step 2 Measure for 0 V AC from the ground pin of the outlet to the building ground.

Step 3 Measure for less than 1-ohm resistance from the ground pin of the outlet to building ground and from the ground pin of the machine power cord to each frame in the library.

Step 4 Measure the customer supplied voltage. The nominal voltage is single phased 110 V AC.

In Europe, the nominal voltage is single phased 230V AC.

Step 5 Connect the AC power cable from the Scalar 100 Library to the customer power source.

Installation CheckoutStep 1 Ensure there is at least one cartridge in the storage

area of the library. The cartridge must be the type used in the tape drives installed in the Scalar 100. Make sure that the front door of the library is closed.

Step 2 Make sure the Main Switch on the AC Input Power Module in the back of the library is turned on.

Step 3 Turn the Power On/Off Switch on the Scalar 100 front door to on.

Step 4 The library firmware will initialize and begin the Teach/Inventory process automatically. This process can take several minutes depending on the number of drives installed in the library.

Step 5 Run library demo from the Operator Panel (Main Menu >More >Service >Exercise >Demo). Run this test for at least five cycles.

Step 6 Set the date and time using the Operator Panel (Main Menu >More >Utils >Library >Date/Time).

The next step assumes that a correct SCSI adapter and appropriate device driver have been installed on the host system.

Step 7 Power on the host and watch for the BIOS string that’s generated when the SCSI controller is loaded. Once the controller does a query, the ID and inquiry string for the Scalar 100 should be displayed.

If the Scalar 100 is recognized by the SCSI controller, installation is successful, proceed to the next section.

If the Scalar 100 SCSI ID and inquiry string is not displayed, check to make sure that:

a. the SCSI controller is properly installed.

b. the SCSI cable is properly connected between the controller and the library.

c. the SCSI bus is properly terminated.

Post-InstallationStep 1 The library is installed. Give the customer the key,

this is used to open the front door to load the magazines with cartridges.

Step 2 Complete the installation record. The Scalar 100 serial number is located on the product label affixed on the back of the library.

Step 3 Store the items shipped with the library in a safe place. Keep them available for service activity.
