CAUTION:Removing components from the upper positions in the rack cabinet improvesrack stability during relocation. Follow these general guidelines whenever yourelocate a populated rack cabinet within a room or building:

v Reduce the weight of the rack cabinet by removing equipment starting at thetop of the rack cabinet. When possible, restore the rack cabinet to theconfiguration of the rack cabinet as you received it. If this configuration is notknown, you must do the following:

– Remove all devices in the 32U position and above.

– Ensure that the heaviest devices are installed in the bottom of the rackcabinet.

– Ensure that there are no empty U-levels between devices installed in therack cabinet below the 32U level.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to eliminatepotential hazards.

– Verify that the route that you choose can support the weight of the loadedrack cabinet. Refer to the documentation that came with your rack cabinetfor the weight of a loaded rack cabinet.

– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

– Ensure that all devices, shelves, drawers, doors, and cables are secure.

– Ensure that the four leveling pads are raised to their highest position.

– Ensure that there is no stabilizer bracket installed on the rack cabinetduring movement.

– Do not use a ramp inclined at more than 10 degrees.

– Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rackcabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to theconfiguration of the rack cabinet as you received it. Pack the rack cabinet inthe original packaging material, or equivalent. Also, lower the levelingpads to raise the casters off of the pallet and bolt the rack cabinet to thepallet.

Chapter 1. Introducing the SAN24B-4 Express switch

The IBM System Storage SAN24B-4 Express is a cost-effective and highly-scalable1, 2, 4, or 8 Gbit/sec switch, designed for small to mid-sized businesses. It runs onthe Fabric Operating System (Fabric OS) and is compatible with other IBMswitches, which enables seamless connectivity into heterogeneous SANenvironments. This switch is a dual purpose device that you can use either as afull-functioned switch or as an N_Port ID Virtualization (NPIV) access gateway.When functioning as an access gateway, the it provides a single platform for allSAN connectivity. Because the switch is scalable, you can use it as a foundationswitch for a small storage area network (SAN) and continue to use it as a buildingblock as the SAN grows.

Nonport side of the switchThe nonport side of the switch is used solely for air flow. There are no features onthis side.

Supported fabric configurationsThe switch is supported as an edge device in fabrics of up to 239 switches.

Additional port activationThe switch can be purchased with 8, 16, or 24 licensed ports. As your needsincrease, you can activate unlicensed ports by purchasing and installing theadditional 8 port activation feature. After it has been installed, the license appearsunder the licenseShow command as Ports on Demand license.

The additional ports are ready to be unlocked in the switch firmware. The licensemight be part of the licensed paper pack supplied with switch software, or you canpurchase the license separately from IBM, who will provide you with a key tounlock it.

By default, ports 0 through 7 are enabled on the switch. To enable ports 8 through16, install a Ports on Demand license key. To enable ports 16 through 24, installanother Ports on Demand license.

After you have installed the license keys, you must enable the ports. You can do sowithout disrupting switch operation by using the portEnable command on eachport individually. Alternatively, you can disable and reenable the switch to activateall ports simultaneously.

To install the additional port activation license, you can either use the suppliedlicense key or generate a license key. Typically the switch is shipped with a paperpack that specifies the transaction key to use with the Software License Keys link.

Use this transaction key at the following Web site: http://www.ibm.com/servers/storage/support/san.1. On that page, from the Product list, select your product.2. Select Download from the Support & downloads section.3. From the page that is generated, select License request in the Tool/utility

section.4. Follow the instructions on that page to generate the key. You can also use this

site to generate other license keys for your switch.

ISL Trunking groupsThe switch supports Interswitch Link (ISL) Trunking as a licensed feature. Whenthis feature is enabled, create Trunked groups of up to 8 contiguous ports. Thismeans that you can create up to three trunked groups that contain 8 ports each.The Fibre Channel ports on the switch are numbered from left to right andcolor-coded within groups of eight to indicate which ports you can combine intotrunked groups.

v A–Trunk Group 1: ports 0 through 7v B–Trunk Group 2: ports 8 through 15v C–Trunk Group 3: ports 16 through 23

Note: ISL Trunking is optional software that allows you to create trunking groupsof ISLs between adjacent switches. For more information about trunking,refer to the Fabric OS Administrator’s Guide.

Supported optional featuresThe switch supports the following optional software, which you can activate bypurchasing the corresponding license key:v Extended Fabric–allows implementation of long distance dynamic (LD) and long

distance static (LS) distance levels. This feature extends SAN fabrics beyond theFibre Channel standard 10 km by optimizing the internal switch buffers tomaintain performance on ISLs at distances up to 500 kilometers.

v Fabric Watch–monitors mission-critical switch operations. This feature isdesigned to enable real-time proactive awareness of the health, performance, andsecurity of each switch. It automatically alerts network managers to problemsand helps avoid costly failures by providing:– Real-time tracking of numerous fabric and switch elements– Automatic event notifications when switch and fabric elements exceed

thresholds– Security, availability, and congestion monitoring thresholds and alerts

v Adaptive Networking– provides a set of capability allowing high priorityconnections to obtain the bandwidth necessary for optimum performance, evenin congested environments.

v Advanced Performance Monitor–provides Performance Monitoring capability tohelp identify end-to-end bandwidth usage by host/target pairs and is designedto provide information for capacity planning.

v Trunking Activation–designed to enable Fibre Channel packets to be efficientlydistributed across multiple Inter-Switch connections (links) between two SANb-type fabric switches, while preserving in-order delivery. ISL Trunking issupported between any of the supported 2, 4, or 8 Gbps b-type models. BothSAN b-type fabric switches must have ISL Trunking activated.

v Server Application Optimization (SAO)–designed to bring Quality of Service(QoS) enhancements for server consolidation and virtualization

In addition, customers can order a set of optional features bundled into oneorderable feature, the B24 Enterprise Package. This bundled feature consists of oneof each of Fabric Watch, Trunking Activation, Advanced Performance Monitor,Adaptive Networking, and two 8-Port Activations.

Chapter 2. Installing and configuring the switch

You can install the switch in either of two ways:v As a stand-alone unit on a flat surfacev In an Electronic Industries Association (EIA) cabinet using a slide-rail rack

mount kit, which is provided with the switch. When you mount the switch intoa slide-rail rack, you can mount the chassis to slide from either the port side orthe non-port side.

The SAN24B-4 can be configured and operated as either a SAN fabric switch or asan Access Gateway. The configuration instructions in this publication are for theSAN24B-4 to operate as a switch. The installation instructions in this documentapply to both Switch and Access Gateway modes. To configure and operate theSAN24B-4 in Access Gateway mode, refer to the IBM System Storage SAN24B-4Access Gateway Quick Start Guide and the Access Gateway Administrator's Guide.

Attention: When you enable Access Gateway mode, you disable the ability forthe SAN24B-4 to operate as a switch. Access Gateway mode and switch mode aremutually exclusive. If you want to use the SAN24B-4 as a switch at a later time,you will need to disable Access Gateway mode and enable switch mode. Changingbetween Access Gateway and Switch modes is a data disruptive operation. It isstrongly recommended that you disable the switch from the command lineinterface before enabling or disabling Access Gateway mode.

Installation and safety considerationsUse this section to prepare your site for a safe and successful installation.

Attention: Although the switch has been designed for customer installation andreplacement procedures, you must first ensure that the rack into which the switchis to be installed is also customer accessible. If it is not, then only trained personnelcan install and service these switches in such a rack.

Attention: Read the “Safety and environmental notices” on page xivbefore attempting any installation or maintenance procedures.

The switch can be installed either as a free-standing unit, or installed in an EIAcabinet, using an optional slide-rail rack mount kit. When mounting into aslide-rail rack, you can mount the chassis to slide from either the port side or thenonport side.

Electrical considerationsTo install and operate the switch successfully, ensure the following:v The primary outlet is correctly wired, protected by a circuit breaker, and

grounded in accordance with local electrical codes.v The supply circuit, line fusing, and wire size are adequate, as specified by the

electrical rating on the switch nameplate.v The power supply standards provided in “Power supply specifications” on page

36 are met.

Environment considerationsFor successful installation and operation of the switch, ensure that the followingenvironmental requirements are met:v At a minimum, adequate cooling requires that you install the switch with the

nonport side, which contains the air intake vents, facing the cool-air aisle.v All equipment in the rack should force air in the same direction to avoid

intaking exhaust air.v A minimum of 680 l/min (24 cubic ft/min) of air flow is available to the air

intake vents on the nonport side of the switch.v The ambient air temperature does not exceed 40° C (104° F) while the switch is

operating.

Cabinet considerations

Attention: See “Rack safety” on page xx for danger and caution notices related toproduct installations in racks or cabinets.

For successful installation and operation of the switch in a cabinet, ensure that thefollowing cabinet requirements are met:v The cabinet must be a standard EIA cabinet.

8 SAN24B-4 Express Installation, Service, and User Guide

Page 33: b2402mst

v Plan a cabinet space that is 1 rack unit 4.45 cm (1.75 in.) high, 48.3 cm (19 in)wide.

v Ground all equipment in the cabinet through a reliable branch circuit connectionand maintain ground at all times. Do not rely on a secondary connection to abranch circuit, such as a power strip.

v Ensure that airflow and temperature requirements are met on an ongoing basis,particularly if the switch is installed in a closed or multicabinet assembly.

v Verify that the additional weight of the switch does not exceed the cabinet’sweight limits or unbalance the cabinet in any way.

v Secure the cabinet to ensure stability in case of unexpected movement, such asan earthquake.

Installing a stand-alone switchTo install the switch as a stand-alone unit, use the following procedure:1. Unpack the switch and verify the items listed in “Items included with the

switch” on page 72. Apply the adhesive rubber feet. Applying the rubber feet onto the switch helps

prevent the switch from sliding off the supporting surface.a. Clean the indentations at each corner of the bottom of the switch to ensure

that they are free of dust or other debris that might lessen the adhesion ofthe feet.

b. With the adhesive side against the chassis, place one rubber foot in eachindentation and press into place.

3. Place the switch on a flat, sturdy surface.4. Provide power to the switch as described in “Powering the switch on and off”

on page 21.

Attention: Do not connect the switch to the network until the IP address iscorrectly set. For instructions on how to set the IP address, see “Configuring theswitch” on page 16.

Installing the switch into an EIA cabinet

Attention: Although the switch has been designed for customer installation andreplacement procedures, you must first ensure that the rack into which the switchis to be installed is also customer accessible. If it is not, then only trained personnelcan install and service these switches in such a rack.

Attention: Read the “Safety and environmental notices” on page xivbefore attempting any installation or maintenance procedures.

Attention: Refer to “Rack safety” on page xx for danger and caution noticesrelated to rack and cabinet installations.

You can install the rack mount kit in either of two ways:v To allow the port side of the switch to slide out of the exhaust-air side of the

cabinet. In this installation, the port side of the switch is flush with the edge ofthe cabinet.

Chapter 2. Installing and configuring the switch 9

Page 34: b2402mst

v To allow the non-port side of the switch to slide out the cool-air side of thecabinet. In this installation, the port side of the switch is set 7.62 cm (3 in.) backfrom the edge of the cabinet, allowing a more gradual bend in the fiber opticcables.

Time requiredApproximately 30 minutes

9. Continue with initial setup of the switch by following the procedures in“Configuring the switch” on page 16.

DANGER

An electrical outlet that is not correctly wired could placehazardous voltage on metal parts of the system or the devices thatattach to the system. It is the responsibility of the customer toensure that the outlet is correctly wired and grounded to preventan electrical shock. (D004)

Note: Do not connect the switch to the network until you perform one of thefollowing steps:v Set the internet protocol (IP) address.v Verify that the default IP address does not conflict with the existing IP

addresses in the same network.

Recommendations for cable management

Attention: The minimum bend radius for a 50 micron cable is 51 mm (2 in.)under full tensile load and 30.5 mm (1.2 in.) with no tensile load.

SJ000049

Figure 7. Inserting slides into the rack rails

Chapter 2. Installing and configuring the switch 15

Page 40: b2402mst

Cables can be organized and managed in a variety of ways: for example, usingcable channels on the sides of the cabinet or patch panels to minimize cablemanagement. Following is a list of recommendations:v Plan for rack space required for cable management before installing the switch.v Leave at least 1 meter (3.28 ft) of slack for each port cable. This provides room

to remove and replace the switch, allows for inadvertent movement of the rack,and helps prevent the cables from being bent to less than the minimum bendradius.

v If you are using Brocade ISL Trunking, consider grouping cables by trunkinggroups. The cables used in trunking groups must meet specific requirements, asdescribed in the Fabric OS Administrator's Guide.

v For easier maintenance, label the fiber optic cables and record the devices towhich they are connected.

v Keep LEDs visible by routing port cables and other cables away from the LEDs.v Use hook-and-loop fasteners to secure and organize fibre optic cables. Do not

use tie wraps on fiber optic cables, because wraps are easily overtightened andcan damage the optic fibers.

Configuring the switchYou must configure the switch to ensure correct operation within a network andfabric. For instructions about how to configure the switch to operate in a fabricthat contains switches from other vendors, refer to the Fabric OS Administrator'sGuide.

For more information about the commands used in this procedure, refer to theFabric OS Command Reference Manual.v “Using the EZSwitch setup (optional)”v “Providing power to the switch”v “Creating a serial connection” on page 17v “Setting the switch IP address” on page 17v “Setting the date and time” on page 18

Using the EZSwitch setup (optional)Once you have set up the switch in a rack or as a stand-alone switch, it is time togive it power and a basic configuration. If you are going to use the switch in asingle-switch setup, you can use EZSwitchSetup to complete the basicconfiguration. See the EZSwitchSetup CD included with the accessory kit for moreinformation. You can also use the SAN24B-4 Quick Start Guide. If you do not wantto use EZSwitch Setup, use the instructions in following sections.

Providing power to the switchTo provide power to the switch:1. Connect the power cord to the power receptacle on the port side of the switch,

and then to the power source. Ensure that the cord has a minimum service loopof 15 cm (6 in.) available and is routed to avoid stress.The switch does not have a on/off power switch. This means that power issupplied to the switch as soon as you connect it to an AC power source.The status LEDs display amber until POST is complete, and then change togreen. The switch usually requires from 1 to 3 minutes to boot and completePOST.

16 SAN24B-4 Express Installation, Service, and User Guide

Page 41: b2402mst

2. After POST is complete, verify that the switch power and status LEDs on theleft of the port side of the switch are green.

Creating a serial connectionYou will perform all basic configuration tasks in this guide using a serialconnection. To create a serial connection to the switch, complete the followingsteps:1. Connect the serial cable to the serial port on the switch and to an RS-232 serial

port on the workstation.If the serial port on the workstation is RJ-45 instead of RS-232, remove theadapter on the end of the serial cable and insert the exposed RJ-45 connectorinto the RJ-45 serial port on the workstation.

2. Disable any serial communication programs running on the workstation.3. Open a terminal emulator application (such as HyperTerminal on a PC, or

TERM, TIP, or Kermit in a UNIX® environment), and configure the applicationas follows:v In a Windows® environment:

Bits per second 9600

Databits 8

Parity None

Stop bits 1

Flow control Nonev In a UNIX environment, type the following string at the prompt:

tip /dev/ttyb -9600If ttyb is already in use, use ttya instead and enter the following string at theprompt:tip /dev/ttya -9600

Setting the switch IP addressYou can configure the switch with a static IP address, or you can use a DHCP(Dynamic Host Configuration Protocol) server to set the IP address of the switch.DHCP is enabled by default. The switch supports both IPv4 and IPv6.

Using DHCPWhen using DHCP, the switch obtains its IP address, subnet mask, and defaultgateway address from the DHCP server. The DHCP client can only connect to thea DHCP server that is on the same subnet as the switch. If your DHCP server isnot on the same subnet as the switch, use a static IP address.

Setting a static IP address1. Log into the switch using the default password, which is password.2. Use the ipaddrset command to set the Ethernet IP address.

If you are going to use an IPv4 IP address, enter the IP address in dotteddecimal notation as prompted.Ethernet IP Address: [192.168.74.102]

If you are going to use an IPv6 address, enter the network information insemicolon-separated notation as prompted.

Page 42: b2402mst

switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64IP address is being changed...Done.

3. Complete the rest of the network information as prompted.

Ethernet Subnetmask: [255.255.255.0]Ethernet IP Address: [192.168.74.102]Ethernet Subnetmask: [255.255.255.0]

4. Enter off to Disable DHCP when prompted.DHCP [OFF]: off

Setting the date and timeThe switch maintains the current date and time inside a battery-backed real-timeclock (RTC) circuit. Date and time are used for logging events. Switch operationdoes not depend on the date and time; a switch with an incorrect date and timevalue still functions properly. However, because the date and time are used forlogging, error detection, and troubleshooting, you should set them correctly.

Setting the date1. If you are not already logged into the switch; do so now using the default

password, which is password.2. Enter the date command, using the following syntax:

date "mmddHHMMyy"

The values represent the following:v mm is the month; valid values are 01 through 12v dd is the date; valid values are 01 through 31v HH is the hour; valid values are 00 through 23v MM is minutes; valid values are 00 through 59v yy is the year; valid values are 00 through 99 (values greater than 69 are

interpreted as 1970 through 1999, and values less than 70 are interpreted as2000-2069)

switch:admin> dateFri Sep 29 17:01:48 UTC 2007switch:admin> date "0927123007"Thu Sep 27 12:30:00 UTC 2007switch:admin>

Setting time zonesYou can set the time zone for a switch by name. You can specify the setting usingcountry and city or time zone parameters.If the time zone is not set with the new options, the switch retains the offset timezone settings. The tsTimeZone command also includes an option to revert to theprior time zone format. For more information about the tstimezone [--old] option,see the Fabric OS Command Reference Manual.

You can set the time zone for a switch using the tsTimeZone command. ThetsTimeZone command allows you to perform the following tasks:v Display all of the time zones supported in the firmwarev Set the time zone based on a country and city combination or based on a time

zone ID such as PST

18 SAN24B-4 Express Installation, Service, and User Guide

Page 43: b2402mst

The time zone setting has the following characteristics:v You can view the time zone settings. However, only those with administrative

permissions can set the time zones.v The tsTimeZone setting automatically adjusts for Daylight Savings Time.v Changing the time zone on a switch updates the local time zone setup and is

reflected in local time calculations.v By default, all switches are in the GMT time zone (0,0). If all switches in a fabric

are in one time zone, it is possible for you to keep the time zone setup at thedefault setting.

v System services that have already started will reflect the time zone changes onlyafter the next reboot.

v Time zone settings persist across failover for high availability.

The following procedure describes how to set the time zone for a switch. You mustperform the procedure on all switches for which the time zone must be set.However, you only need to set the time zone once on each switch, because thevalue is written to nonvolatile memory.1. If you are not already logged into the switch; do so now using the default

password, which is password.2. Enter the tsTimeZone command as follows:

switch:admin> tstimezone [--interactive]/ [, timezone_fmt]

Use timezone_fmt to set the time zone by Country/City or by time zone ID,such as PST.The following example shows how to display the current time zone setup andhow to change the time zone to US/Central.

switch:admin> tstimezoneTime Zone : US/Pacificswitch:admin> tstimezone US/Centralswitch:admin> tstimezoneTime Zone : US/Central

The following procedure describes how to set the current time zone usinginteractive mode to Pacific Standard Time.

1. Type the tsTimeZone command as follows:switch:admin> tstimezone --interactive

2. You are prompted to select a general location.Please identify a location so that time zone rules can be set correctly.

3. Enter the appropriate number or Ctrl-D to quit.4. At the prompt, select a country location.5. At the prompt, enter the appropriate number to specify the time zone region or

Ctrl-D to quit.

Synchronizing local time using NTPYou can synchronize the local time of the principal or primary fabric configurationserver (FCS) switch to a maximum of eight external network time protocol (NTP)servers. To keep the time in your SAN current, it is recommended that theprincipal or primary FCS switch has its time synchronized with at least oneexternal NTP server. The other switches in the fabric will automatically take theirtime from the principal or primary FCS switch.

Chapter 2. Installing and configuring the switch 19

Page 44: b2402mst

All switches in the fabric maintain the current clock server value in non-volatilememory. By default, this value is the local clock server <LOCL> of the principal orprimary FCS switch. Changes to the clock server value on the principal or primaryFCS switch are propagated to all switches in the fabric.

For more information on using an NTP server, and IPv6 considerations, see theFabric OS Administrator’s Guide.1. If you are not already logged into the switch; do so now using the default

password, which is password.2. Enter the tsClockServer command:

switch:admin> tsclockserver "<ntp1;ntp2>"

where ntp1 is the IP address or DNS name of the first NTP server, which theswitch must be able to access. The second ntp2 is the second NTP server and isoptional. The operand “<ntp1;ntp2>” is optional; by default, this value isLOCL, which uses the local clock of the principal or primary switch as theclock server.

The tsClockServer command accepts multiple server addresses in either IPv4, IPv6,or DNS name formats. When multiple NTP server addresses are passed,tsclockserver sets the first obtainable address as the active NTP server. The restwill be stored as backup servers that can take over if the active NTP server fails.The principal or primary FCS switch synchronizes its time with the NTP serverevery 64 seconds.

switch:admin> tsclockserverLOCLswitch:admin> tsclockserver "132.163.135.131"switch:admin> tsclockserver132.163.135.131switch:admin>

The following example shows how to set up more than one NTP server using aDNS name:

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"Updating Clock Server configuration...done.Updated with the NTP serversChanges to the clock server value on the principal or primary FCS switchare propagated to all switches in the fabric.

Chapter 3. Operating the switch

This chapter provides the following information:v “Powering the switch on and off”v “Interpreting LED activity”v “LED patterns” on page 23v “POST and boot specifications” on page 25v “Interpreting POST results” on page 26v “Switch FRU units” on page 26v “Maintaining the switch” on page 26v “Managing the switch” on page 30v

Powering the switch on and offSee Chapter 2, “Installing and configuring the switch,” on page 7 for initial setupinstructions before powering the switch on for the first time. Once the switch hasbeen properly configured, follow these instructions to power the switch on and off.

The SAN24B-4 does not have an AC power switch. To power on the SAN24B-4,connect the power cable to the AC receptacle on the switch and to a power source.The switch runs POST by default each time it is powered on, reset, or rebooted,and requires a minimum of three minutes to run. To end the flow of power to theswitch, remove the power cord from the power source.

Interpreting LED activitySystem activity and status can be determined through the activity of the LEDs onthe switch. All LEDs are located on the port side of the switch. There are threepossible LED states: no light, a steady light, and a flashing light. The steady lightsand flashing lights can be green or amber. The LEDs flash either of these colorsduring boot, POST, or other diagnostic tests. This is normal and does not indicate aproblem unless the LEDs do not indicate a healthy state after all boot processesand diagnostic tests are complete.

The switch has the following LEDs:v System power LED–One LED (green) to indicate system powerv System status LED–One LED (green/amber) to indicate system statusv Ethernet status LEDs–Two LEDs to indicate speed and link statusv Port status LEDs–24 LEDs (green/amber) to indicate status for each port

POST and boot specificationsWhen the switch is turned on or rebooted, the switch performs POST. Total boottime with POST is up to 3 minutes. POST can be omitted after subsequent rebootsby using the fastboot command or entering the diagDisablePost command topersistently disable POST.

For more information about these commands, refer to the Fabric OS CommandReference Manual.

POSTThe success or failure results of the diagnostic tests that run during POST can bemonitored through the error log or the command line interface.

POST includes the following steps:1. Preliminary POST diagnostics are run.2. Operating system is initialized.3. Hardware is initialized.4. Diagnostic tests are run on several functions, including circuitry, port

functionality, memory, statistics counters, and serialization.

BootIn addition to POST, boot includes the following steps after POST is complete:1. Universal port configuration is performed.2. Links are initialized.3. Fabric is analyzed, and if any ports are connected to other switches, the switch

participates in a fabric configuration.4. Switch obtains a domain ID and assigns port addresses.5. Unicast routing tables are constructed.6. Normal port operation is enabled.

Interpreting POST resultsPOST is a system check that is performed each time the switch is powered on,rebooted, or reset. During POST, the LEDs flash amber and green. Any errors thatoccur during POST are listed in the error log.

To determine that POST completed successfully and whether or not any errorswere detected:1. Verify that the switch LEDs indicate that all components are healthy. See

Table 4 on page 23 through Table 7 on page 25 for the description andinterpretation of LED patterns. If one or more LEDs do not display a healthystate, verify that the LEDs on the switch are not set to “beacon”; use theswitchShow command to detect if beaconing is active.

2. Verify that the switch prompt displays on the terminal of a computerworkstation connected to the switch. If there is no switch prompt when POSTcompletes, press Enter. If the switch prompt still does not display, try openinganother telnet session or accessing through another management tool. If this isnot successful, the switch did not successfully complete POST; contact IBMService for repair.

3. Review the switch system log for errors. Any errors detected during POST arewritten to the system log, which is accessible through the errShow command.

For information about all referenced commands, and on accessing the error log,refer to Fabric OS Administrator's Guide. For information about error messages, referto the Fabric OS System Error Message Reference Manual.

Switch FRU unitsThe only parts for this switch that are field replaceable are the SFPs. The entireswitch is a FRU. The fan units and power supply are not field replaceable in thisswitch.

Maintaining the switchThe switch does not require any regular physical maintenance; it was designed tominimize the chance of failure. Ensure that the environmental conditions,described in “Environment considerations” on page 8, are met. This helps preventfailure of the switch due to distress or abuse.

Installing SFPsThe switch only supports Brocade-branded SFPs. If you use an unqualified SFP, theswitchShow command output will show the port in an Mod_Inv state. Fabric OSwill also log the issue in the system error log.

Follow these instructions to install an SFP:1. Making sure that the bail (wire handle)�B� is in the unlocked position, place

the SFP in the correctly oriented position on the port, as shown in Figure 9 onpage 27

Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.The correct position to insert an SFP into the upper row of ports is withthe gold edge down. The correct position to insert an SFP into the lowerrow of ports is with the gold edge up.

2. Slide the SFP into the port until you feel it click into place; then close the bail.

E Cabled Fibre Channel ports

Testing a port, SFP, and fiber cableThe PortLoopbackTest command is used to verify the functional operation of theswitch by sending frames from the port "N" transmitter and looping them backinto the same port "N" receiver. The loopback is done at the parallel loopback path.The path exercised in this test does not include the media or the fiber cable.However if data transmission errors indicate that a port, SFP or cable are faulty,you can use this command to determine whether the port is faulty. You can usethose results to isolate the problem to either the port or the SFP and cablecombination. If a port is faulty, the switch will need to be replaced. If the port isnot faulty, the problem is either with the SFP or the cable.

With this command, only one frame is transmitted and received at a time. Noexternal cable is required to run this test. The port LEDs flicker rapidly (green)while the test is running.

The test performs the following operations:1. Sets all ports for parallel loopback.2. Creates a frame F of maximum data size (2,112 bytes).3. Transmits the frame F through port "N".4. Picks up the frame from the same port "N".5. Checks the eight statistic error counters for nonzero values:

ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet, DiscC3

6. Checks whether the transmit, receive, or class 3 receiver counters are stuck atsome value.

7. Checks whether the number of frames transmitted is not equal to the numberof frames received.

8. Repeats Steps 2 through 7 for all ports until one of the following conditionsare met:a. The number of frames (or passcount) requested is reached.b. All ports are marked bad.

At each pass, the frame is created from a different data type. If seven passesare requested, seven different data types are used in the test. If eight passesare requested, the first seven frames use unique data types, and the eighth isthe same as the first. The seven data types are:

CSPAT: 0x7e, 0x7e, 0x7e, 0x7e, ...BYTE_LFSR: 0x69, 0x01, 0x02, 0x05, ...CHALF_SQ: 0x4a, 0x4a, 0x4a, 0x4a, ...QUAD_NOT: 0x00, 0xff, 0x00, 0xff, ...CQTR_SQ: 0x78, 0x78, 0x78, 0x78, ...CRPAT: 0xbc, 0xbc, 0x23, 0x47, ...RANDOM: 0x25, 0x7f, 0x6e, 0x9a, ....

9. If the test indicates that all ports are good, the problem is associated witheither the cable or SFP.

10. Replace the SFP with an SFP known to be good.

Chapter 3. Operating the switch 29

Page 54: b2402mst

11. Simulate the data transmission scenario when the error occurred. If the errordoes not reappear, the original SFP was defective, and should be discarded. Ifthe error does reappear, the cable is defective. Replace the cable and discardthe original cable.

12. Simulate the data transmission scenario again to verify that the problem doesnot reappear.

Diagnostic testsIn addition to POST, Fabric OS includes diagnostic tests to help troubleshoot thehardware and the firmware. This includes tests of internal connections andcircuitry, fixed media, and the SFPs and cables in use.The tests are implemented by command, either through a Telnet session or througha terminal set up for a serial connection to the switch. Some tests require the portsto be connected by external cables, to allow diagnostics to verify theserializer/deserializer interface, SFP, and cable.All diagnostic tests are run at link speeds of 1, 2, 4, and 8 Gbps, depending on thespeed of the link being tested.

Attention: Diagnostic tests can temporarily lock the transmit and receive speed ofthe links during diagnostic testing.

For information about specific diagnostic tests, refer to the Fabric OS Administrator’sGuide.

Managing the switchYou can use the management functions built into the switch to monitor the fabrictopology, port status, physical status, and other information to help you analyzeswitch performance and to accelerate system debugging. The switch automaticallyperforms power-on-self-test (POST) each time it is turned on. Any errors arerecorded in the error log. For more information about POST, see “POST and bootspecifications” on page 25.

For information about upgrading the version of Fabric OS installed on your switch,refer to the Fabric OS Administrator’s Guide. You can manage the switch using anyof the management options listed in Table 8.
