The IBM System Storage SAN42B-R switch is intended as a platform for FibreChannel over IP (FCIP). This enables transmission of Fibre Channel data over longdistances by way of IP networks by wrapping Fibre Channel frames in IP packets.Each end of the FCIP communication path must be a compatible FCIP device. Theswitch can operate independently or in a fabric containing multiple extensionswitches.

SAN42B-R software features

The SAN42B-R provides the following software features.v Multiple logical FCIP tunnels with maximum tunnel bandwidth up to 20 Gbps

allow for scalable connectivity between sites. Note that the SAN42B-R does notsupport FCIP connectivity with any other products including the SAN06B-R andthe FX8-24 blade.

v FCIP Trunking feature allows multiple IP source and destination address pairs(defined as FCIP circuits) via multiple 1/10 GbE or 40 GbE interfaces to providehigh bandwidth FCIP tunnel and lossless failover resiliency. In addition, eachFCIP circuit supports four QoS classes (Class-F, High, Medium and LowPriority), each as a TCP connection.

v ARL feature meets minimum bandwidth guarantee for each tunnel whilemaking the full utilization of the available network bandwidth without adversethroughput performance impact at high traffic load.

v Hardware-based compression delivers the ability to maximize throughput overlower bandwidth links in the wide area network, optimizing the cost efficienciesof FCIP. The SAN42B-R compresses FC frames before they are encapsulated intoFCIP packets.

v Key protocol features are enabled in the FCIP implementation to optimizeperformance of Extension over IP networks, including FX8-24 and WANOptimized TCP (WO-TCP), 9K jumbo frame and end-to-end Path MTU autodiscovery.

v Hardware-based IPsec supports mix of secure and non secure tunnels on thesame Ethernet port, jumbo frames, and VLAN tagged connections. The IPsecfunction is capable of supporting both IPv4 and IPv6.

v FastWrite, Open Systems Tape Pipelining and Advanced Accelerator for FICON®

mitigate the latency effect of a long distance FCIP distance connection over IPWAN.

v FCIP HCL (Hot Code Load) provides In-service firmware upgrade forsupporting 24/7 nonstop business operations.

v Built-in WAN link tester generates traffic over an IP connection to test formaximum throughput, congestion, loss percentage, out of order deliver, latency,and other network conditions. It helps determine the health of a WAN linkbefore deploying it for use.

v Fabric Vision advanced monitoring provides the following functions:– Policy based monitoring monitors FCIP connectivity and WAN anomalies

using multi-layer metrics.– Flow monitoring reports IOPS and data rate of individual I/O flows of

inter-DC replication and tape backup operations.

© Copyright IBM Corp. 2014, 2017 1

– Flow generator generates FC frames for a defined flow with default orcustom size and pattern and sent across FCIP tunnel to help validateend-to-end network setup and configuration.

v Fabric OS delivers distributed intelligence throughout the network and enables awide range of value-added applications.

Chapter 2. Installing and configuring the switch

You can install the SAN42B-R switch in the following ways:v As a stand-alone unit on a flat surface. For instructions and more information,

see “Setting up the switch as a standalone unit” on page 10.v In an Electronic Industries Association (EIA) cabinet using the fixed rack mount

kit. For more information, see “Installing in an EIA cabinet” on page 10.

Use the following information to complete the installation and configuration.v “Site preparation and installation requirements”v “Items included with the switch” on page 9v “Setting up the switch as a standalone unit” on page 10v “Installing in an EIA cabinet” on page 10v “Initial setup of the switch” on page 21

Attention: Read the “Safety notices and labels” on page xi before attempting anyinstallation, maintenance, or service procedures.

Site preparation and installation requirementsThe following conditions are required to ensure correct installation and operationof the switch.

Attention: Follow ESD precautions whenever handling the switch or components.See “ESD precautions” on page xvii.

Electrical requirements

For successful installation and operation of the switch, ensure that the followingelectrical requirements are met:v The primary outlet is correctly wired, protected by a circuit breaker, and

grounded in accordance with local electrical codes.v It is best practice that each power supply obtain its power from a different

protected and wired source.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 are met. See “Power supply specifications” on page

58.Attention: To maximize fault tolerance, connect each power cord to a separatepower source.

Environmental considerations

For 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

intake side (non port side), facing the cool-air aisle.


v All equipment in the rack should force air in the same direction to avoid intakeof exhaust air.

v Airflow requirements outlined in “Environmental requirements” on page 57must be met.

v The ambient air temperature does not exceed 40° C (104° F) while the switch isoperating.

Cabinet requirements

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.v Plan for a rack space that is two rack units (2U) high; 8.90 cm (3.50 in.) high and

48.3 cm (19 in.) wide, and at least 61 cm (24 in.) deep.v Ground all equipment in the rack through a reliable branch circuit connection

and 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.v Verify that the additional weight of the switch does not exceed the rack’s weight

limits or unbalance the rack in any way.v The cabinet must be secured to ensure stability in case of unexpected movement,

such as an earthquake.

Planning for cable management

Attention: The minimum bend radius for a 50 micron cable is 5.1 cm (2 in.)under full tensile load and 3.0 cm (1.2 in.) with no tensile load.

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. Use this list of recommendations to guide your planning.v Plan for rack space required for cable management before installing the switch.v Leave at least 1 m (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 ISL Trunking, consider grouping cables by trunking groups. Thecables used in trunking groups must meet specific requirements, as described inthe 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 style straps to secure and organize fiber optic cables. Do not

use tie wraps with optical cables; they can be easily overtightened and candamage the optic fibers.

v Record port and cable connections using a table such as Appendix C, “Cablerouting table,” on page 65.

Setting up the switch as a standalone unit

Attention: Refer to “Safety notices and labels” on page xi beforestarting any installation procedure.

To install the switch as a standalone unit, use the following procedure:1. Unpack the switch and verify that all items listed in “Items included with the

switch” on page 9 are present and undamaged.2. Clean the four corner depressions on the bottom of the switch enclosure, place

an adhesive rubber foot in each one, and firmly press into place. The rubberfeet on the switch help prevent the switch from sliding off the supportingsurface.

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

on page 22.

Attention: Do not connect the switch to the network until the IP address iscorrectly set. For instructions on how to cable and configure the switch, and howto set the IP address, see “Initial setup of the switch” on page 21.

Installing in an EIA cabinetThe switch can be installed so that the port side is either flush with the front postsor recessed with the non-port side flush with the rear posts. A recessed positionallows a more gradual bend in the fiber optic cables connected to the switch andless interference in the aisle at the front of the rack.

Note: The illustrations in the installation instructions show a 1U device. TheSAN42B-R is a 2U device but the installation instructions are the same.

Attention: Refer to “Safety notices and labels” on page xi beforestarting any installation procedure.

Attention: Refer to “Rack safety” on page xvii for danger and cautionnotices related to rack and cabinet installations.

Attention: Install the switch with the airflow aligned with any otherswitches in the rack. Some switches have airflow running from port sideto fan side and others have the opposite arrangement. Make sure thatthe airflow for all switches moves in the same direction to maximizecooling.

Time required

Allow 15 to 30 minutes to complete this procedure. Two people can makeinstallation easier.

To configure the switch, complete the following tasks.v “Providing power to the switch”v “Creating a serial connection” on page 23v “Setting the switch IP address” on page 23v “Changing the switch name and chassis name” on page 24v “Creating an Ethernet connection” on page 24v “Setting the domain ID of the switch” on page 24v “Setting the date and time of the switch” on page 25v “Synchronizing local time with an external source” on page 26v “Correcting the time zone of a switch” on page 26v “FCIP and Fibre Channel routing services configuration” on page 27v “Installing SFP+ and QSFP transceivers and connecting cables” on page 27v “Verifying correct operation and backing up the configuration” on page 29

Attention: Do not connect the switch to the network until the IP address iscorrectly set.

Providing power to the switch

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)

Complete these steps to power on the switch:1. Connect the power cords to both power supplies in the chassis.2. Connect the other end of the power cords to power sources on separate circuits

to protect against AC failure. Ensure that the cords have a minimum serviceloop of 15 cm (6 in.) available and are routed to avoid stress.The power supplies provide power to the switch as soon as they are connectedto a power source. Each power supply has two LEDs, one for AC status andone for DC status. Both LEDs turn green within one second of power beingapplied. The power status LED on the port side of the switch turns green assoon as either power supply LED is green. The status LED is amber only untilFOS is loaded and then it turns green. The status LED is green while POST isrunning.Attention: Power is supplied to the switch as soon as the first power supplyis connected to a power source. There are no switches on the power supplies toturn the power on and off.


DANGER

Multiple power cords. The product might be equipped withmultiple power cords. To remove all hazardous voltages,disconnect all power cords. (L003)

3. After POST is complete, verify that the switch power and status LEDs on theleft of the port side of the switch are both green. See “Port side of the switch”on page 3 for the specific location of these LEDs.

Attention: Do not connect the switch to the network until the IP address is set.

Creating a serial connection

All basic configuration tasks in this guide are accomplished using a serialconnection. If you need to know the serial port pinouts, refer to Table 21 on page60.

Complete these steps to log in to the switch through the serial connection.1. Verify that the switch has completed POST. When POST is complete, the port

status and switch power and status LEDs return to a standard healthy state.2. 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 ofRS-232, remove the adapter from the end of the serial cable and insert theexposed RJ-45 connector into the RJ-45 serial port on the workstation.

3. Open a terminal emulator application (such as HyperTerminal on a PC, orTERM, TIP, or Kermit in a UNIX environment), and configure the applicationas follows:v In a Windows environment, use 9600 bits per second, 8 databits, no parity, 1

stop bit, and no flow control.v In a UNIX environment using TIP, enter the following string at the prompt:

tip /dev/ttyb -9600

If ttyb is already in use, then use ttya instead and enter the following stringat the prompt:tip /dev/ttya -9600

Setting the switch IP address

You can configure the switch with a static IP address, or you can use a DynamicHost Configuration Protocol (DHCP) server to set the IP address of the switch.DHCP is enabled by default. The switch supports both IPv4 and IPv6. See theFabric OS Command Reference for details about the ipAddrSet command.

Using DHCP to set the IP address

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

Setting a static IP address


1. Log in to 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.switch:admin> ipaddrsetEthernet IP Address [192.168.74.102]:

If you are going to use an IPv6 address, enter the network information incolon-separated notation as prompted.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. (IPv4 format shownin the example):Ethernet IP Address [192.168.74.102]:Ethernet Subnetmask [255.255.255.0]:Gateway IP Address [192.168.74.1]:

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

5. Optionally, verify that the address was correctly set by entering the ipAddrShowcommand at the prompt.

Changing the switch name and chassis name

Changing the switch and chassis names are important for accurate tracking oferrors in the RASlog. The messages that appear in the log will be labeled with theswitch or chassis name, which makes tracking the errors much easier. Choose aneasily understandable and meaningful name for the switch and chassis names.

Complete the following steps to change the chassis name and then the switchname.1. Log in to the switch through Telnet using the admin account.2. Change the chassis name by using the chassisName command.

switch:admin> chassisname SAN42Bchassis10

3. Change the switch name by using the switchName commandswitch:admin> switchname SAN42Bswitch10

Creating an Ethernet connection

Complete the following steps to create an Ethernet connection to the switch.1. Remove the plug from the Ethernet port.2. Connect an Ethernet cable to the switch Ethernet port and to the workstation or

to an Ethernet network containing the workstation.

Note: At this point, the switch can be accessed remotely by command line or byWeb Tools. Ensure that the switch is not being modified from any otherconnections during the remaining tasks. The Ethernet management port alsosupports AutoMDI/MDIX.

Setting the domain ID of the switch

Complete the following steps to set the switch domain ID.1. Log in to the switch through Telnet using the admin account.2. Modify the domain ID if required.


The default domain ID is 1. If the switch is not powered on until after it isconnected to the fabric and the default domain ID is already in use, the domainID for the new switch is automatically reset to a unique value. If the switch isconnected to the fabric after it has been powered on and the default domain IDis already in use, the fabric segments. To find the domain IDs that are currentlyin use, enter the fabricShow command on another extension switch in thefabric.Complete these steps to modify the Domain ID.a. Disable the switch by entering the switchDisable command.b. Enter the configure command. The command prompts display sequentially;

enter a new value or press Enter to accept each default value.c. Enter y after the "Fabric param" prompt.

Fabric param (yes, y, no, n): [no] y

d. Enter a unique domain ID (such as the domain ID used by the previousextension switch, if still available).Domain: (1..239) [1] 3

e. Complete the remaining prompts or press Ctrl+D to accept the remainingsettings without completing all the prompts.

f. Re-enable the switch by entering the switchEnable command.

Setting the date and time of the switch

The date and time switch settings are used for logging events. Switch operationdoes not depend on the date and time; a switch with incorrect date or time valuesstill functions properly. You can synchronize the local time of the principal orprimary fabric configuration server (FCS) switch to that of an external NetworkTime Protocol (NTP) server.

Complete these steps to set the date and time of a switch.1. Log in to the switch as admin.2. Enter the date command at the command line using the following syntax:

date ["newdate"]

This command has the following operand: "newdate". This operand specifiesthe new date and time enclosed in double quotation marks. this operand isoptional; if omitted, the current date and time is displayed. Date and time arespecified as a string in the mmddhhmmyy format. The syntax uses the followingvalues:v mm: Specifies the month. Valid values are 01 to 12.v dd: Specifies the date. Valid values are 01 to 31.v hh: Specifies the hour. Valid values are 00 to 23.v mm: Specifies the minutes. Valid values are 00 to 59.v yy: Specifies the year, valid values are 00 to 37 and 70 to 99. Year values

from 70 to 99 are interpreted as 1970 to 1999; year values from 00 to 37 areinterpreted as 2000 to 2037.

Synchronizing local time with an external source

Complete the following steps to synchronize the local time of the principal orprimary FCS switch with that of an external NTP server.1. Log in asadmin.2. Enter the tsClockServer ipaddr command.

The ipaddr variable represents the IP address of the NTP server that the switchcan access. This argument is optional; by default, the value is "LOCL".swSAN42BR:admin> tsclockserver 192.168.126.60Updating Clock Server configuration...done.Updated with the NTP servers

Correcting the time zone of a switch

If the time of your switch is off by hours (and not minutes), use the followingprocedure to set the time zone.1. Log in asadmin.2. You can use the tstimezone --interactive command and follow the prompts

or enter the tsTimeZone command as follows:tstimezone [houroffset [, minuteoffset]]

For Pacific Standard Time, enter tsTimeZone -8,0For Central Standard Time, enter tsTimeZone -6,0For Eastern Standard Time, enter tsTimeZone -5,0

The default time zone for switches is universal time conversion (UTC), which is 8hours ahead of Pacific Standard Time. Additional time zone conversions are listedin Table 5. The parameters listed do not apply if the time zone of the switches hasalready been changed from the default (8 hours ahead of Pacific Standard Time).For more information about the command parameters, refer to the tsTimeZonecommand in the Fabric OS Command Reference.

Setting the time zone needs to be done only once, because the value is stored innonvolatile memory. For U.S. time zones, use Table 5 to determine the correctparameter for the tsTimeZone command.

FCIP and Fibre Channel routing services configuration

The ports on the switch are initially set to persistently disabled.

If you want to enable the FC ports as a standard E_Port or F_Port, use theportcfgpersistentenable command to enable the ports.

If you are using the FC ports as EX_Ports, you must configure the Fibre ChannelRouting Services feature before enabling the ports.

Refer to the Fabric OS Administrator's Guide for detailed instructions on configuringthe Fibre Channel router ports and GbE ports on the switch.

Installing SFP+ and QSFP transceivers and connecting cablesComplete the following steps to install SFP+ transceivers and to connect cables tothe switch. The process for installing QSFP transceivers is similar. The transceiversmay already be installed in the switch as shipped. If this is the case, you can eitherjust proceed to attaching the cables, or remove each transceiver, attach the cable,and then reinstall each transceiver and cable as one unit.

Attention: Use only transceivers that are supported for this product. Onlytransceivers purchased from IBM are supported. The use of transceivers that arenot supported may cause data loss or cause the product to malfunction. For alisting of transceivers compatible with this product:v Go to the IBM Support Portal www.ibm.com/supportportal.v In the Search support field, enter b-type supported transceiver and then press

Enter. Click the link on the page that displays.v Alternatively, use this direct link: http://www-01.ibm.com/support/

docview.wss?uid=ssg1S1004421.

If you use an unqualified transceiver, the switchShow command output shows theport in a Mod_Inv state. Fabric OS also logs the issue in the system error log.

The 16 Gbps SFP+ transceivers have an attached pull tab and no latching wire bail.To simplify insertion of the 16 Gbps SFP+ transceivers, IBM recommendsconnecting the cables first, and then inserting them as a unit into the port.Figure 18 on page 29 shows the installation of a 16 Gbps SFP+. All SFP+transceivers are keyed so that they can only be inserted into the ports in the correctorientation. Transceivers should slide easily into the port if aligned correctly.

Installing 16 Gbps SFP+ transceivers

Attention: With increasing speeds of optical connections, the cleanliness of theconnections assumes greater importance in ensuring maximum performance anderror free transmission. Due to the tighter tolerances associated with state of the artoptics, levels of contamination that were acceptable at lower speeds may not be athigher speeds. While IEC Standard 61300-3-35 specifies a set of guidelines fortrouble free performance, most issues can be avoided by adhering to the followingbest practices.v When cables or connectors are not in use for extended periods of time, use the

dust covers provided.v Ensure that the cable length and type that is used are suitable for the speed and

application.v Inspect and clean optical connections and fiber cables before you connect or

reconnect components.v Ensure that cables are properly seated within the connector.

Kits are commercially available for cleaning and inspecting these connections. IBMalso offers services that will ensure optimal condition of the network.

Complete the following steps to install 16 Gbps SFP+ transceivers and cables.1. Remove any protector plugs from the 16 Gbps SFP+ transceiver and the cable.2. Ensure that both cable and transceiver are clean prior to installation.3. Position a cable so that the key (the ridge on one side of the cable connector) is

aligned with the slot in the transceiver. Insert the cable into the transceiveruntil the latching mechanism clicks. Cables are keyed so that they can beinserted in only one way. If a cable does not slide in easily, ensure that it iscorrectly oriented.Attention: Take care not to bend the SFP+ pull tab. Do not insert a cableintended for an mSFP transceiver into a regular SFP+ transceiver. You maydamage the cable.

4. Transceivers are keyed so that they can only be inserted with the correctorientation. Insert the cable/transceiver into the port, using the pull tab to helppush the transceiver into the port. If it does not slide in easily, ensure that it iscorrectly oriented.


5. Repeat steps 1-4 for the remaining SFP+ and QSFP transceivers and cables.

Verifying correct operation and backing up the configurationComplete the following steps to verify correct operation and back up the switchconfiguration.1. Check the LEDs to verify that all components are functional. For information

about LED patterns, refer to “Interpreting LED activity” on page 33.2. Enter the portcfgpersistentenable command to activate the FC ports for FC

operation.3. Verify the correct operation of the switch by entering the switchShow command

3. Review the system log for errors. Errors detected during POST are written tothe system log, which is viewed using the errShow command. For moreinformation about this command, refer to the Fabric OS Command Reference. Forinformation about specific error messages, refer to the Fabric OS MessageReference.

Switch maintenanceThe SAN42B-R is designed for high availability and reliability; it does not requireany regular physical maintenance. The switch includes diagnostic tests andfield-replaceable units, described in the following sections.

Diagnostic tests

In addition to POST, Fabric OS includes diagnostic tests to help you troubleshootthe hardware and firmware. This includes tests of internal connections andcircuitry, fixed media, and the transceivers and cables in use.

The tests are implemented by command, either through a Telnet session or througha serial console connection to the switch. Some tests require the ports to beconnected by external cables to allow diagnostics to verify theserializer/deserializer interface, transceiver, and cable. Some tests require loopbackplugs.

Diagnostic tests run at link speeds of 2, 4, 8, 10, or 16 Gbps depending on thespeed of the link being tested and the type of port. For information about specificdiagnostic tests, see the Fabric OS Administrator's Guide.

Note: Diagnostic tests might temporarily lock the transmit and receive speed ofthe links during diagnostic testing. IBM recommends that you power-cycle theswitch after completing offline diagnostics tests.

Chapter 4. FRU replacementAttention: Read “Safety notices and labels” on page xi before removingor installing any components. Follow ESD precautions (see “ESDprecautions” on page xvii whenever handling FRUs.

The field replaceable units (FRUs) in the SAN42B-R can be removed and replacedwithout special tools. The switch can continue operating during the FRUreplacement if the conditions specified in the procedures are followed.

SFP+ transceiver FRU removal and replacement procedures are described in“Installing SFP+ and QSFP transceivers and connecting cables” on page 27, as partof the initial switch installation and configuration. Power supply and fan FRUremoval and replacement steps are described in the following procedures. Thechassis replacement procedure is to be completed by IBM Service personnel only,and cannot be completed while the switch is operating.

Power supply removal and replacementThe switch has two power supplies, as displayed in Figure 3 on page 5. The FabricOS identifies the power supplies from left to right on the nonport side as powersupply #2 and power supply #1.

Attention: Disassembling any part of the power supply voids the part warrantyand regulatory certifications. There are no user-serviceable parts inside the powersupply. Because the cooling system relies on pressurized air, do not leave either ofthe power supply slots empty longer than two minutes while the switch isoperating. If a power supply fails, leave it in the switch until it can be replaced.Maintain both power supplies in operational condition to provide redundancy.

Refer to Table 7 on page 36 for the power supply status LED colors, behaviors, andactions required, if any.

Determining the need to replace a power supply

Use one of the following methods to determine the status of the power supplies:v Check the power supply AC status and DC status LEDs (see Figure 20 on page

36 ). Both LEDs should be green to indicate that the power supply is functioningcorrectly. If the DC status LED is amber, there is no power on the cord.

v In Web Tools, click the Power Status icon.v At the command prompt, enter the psShow command to display power supply

status as shown in this example below:2498:admin> psshowPower Supply #1 is OKAirflow Direction : Portside Intake (Forward)Power Supply #2 is OKAirflow Direction : Portside Intake (Forward)2498:admin>

Time and items required

Appendix B. Troubleshooting link errors

IBM SAN b-type directors and switches use the latest high bandwidth FibreChannel technology and auto-negotiate to 16 Gbps, 8 Gbps, 4 Gbps, or 2 Gbpsbased on the link data rate capability of the attached transceiver and the speedsupported by the switches and directors. Negotiation to 1 Gbps is not supportedunless 4 Gbps FC transceivers are used. As the 8 and 16 Gbps channel is moresensitive to the condition of the existing multimode and single mode cable plant, itis very important to minimize connector reflections and maintain an acceptablelink loss budget.

This section provides link troubleshooting advice on fault isolation and providesguidance in the following areas:v Dust and dirt contaminationv Link lossv Attenuation on LWL connections

Fault isolation

Since a job loss issue can be caused by a variety of problems, it is important toemploy a systematic fault isolation process to remedy the issue. Note that joblosses do not necessarily result from link errors. They may also be due to:v Configuration issuesv Networking overloadv Failures on storage device, switch, or server

Assume for these procedures that the observed errors originate from link errorsand are not the result of configuration issues, network overload or networkequipment failures.

Whenever CRC errors are discovered on a particular link, it is easy to jump to theconclusion that the link is causing the network issue. This might not be the case.Since CRC errors are just symptoms of a link issue, we need to trace thepropagated error to where it originated.

Figure 27 shows a simplified network involving a server, a switch, and a storagedevice. In this example, assume that the server experienced an error at port 1. Thisobservable error can potentially originate from links 1, 2, 3 or 4 and/or SFP 1, 2, 3or 4.

To determine the original failing link, the observable CRC error needs to betracked back to the first occurrence of the CRC error. By following this process, it

is discovered in this example that CRC errors observed in link 4 were propagatedfrom link 3, which in turn originated from link 2.

Once the original failing link (link 2) has been determined, the two connectingports of that link need to be checked for the following errors:v Encoder errorsv Disparity errorsv Invalid transmission words

The port that displays any of the above errors is the cause of the link issue, whichcan be caused by dust or dirt in the connectors or fiber, an insufficient link lossbudget, and/or incompatible SFPs.

Dust, dirt, or other contaminants

One of the most common optical link problems is caused by dust, dirt, or oil in theconnectors and fiber. 8 and 16 Gbps links are more prone to such issues whilelower link data rates, such as 1, 2, or 4 Gbps may be unaffected.

Once the failing port has been identified by following the above fault isolationprocess, the receive power of the transceiver sitting in that port needs to bedetermined. An abnormally low receive power usually means that the physical linkis dirty.

The receive power can be checked by querying the SFP diagnostics data via thecommand line interface. This information will provide a rough gauge whether thereceive power is abnormally lower than the minimum receive specification of thetransceiver. It is also prudent to compare this receive power with those ofneighboring transceivers.

For better accuracy, it is advisable to use a power meter to measure the actualreceive power of the link. If you are experiencing excessive bit errors and thereceive power of the transceiver is abnormally low, it is recommended that you:v Re-seat the transceivers for the failing linkv Clean the connector and optical fiber

Most link issues are solved by completing these steps.

Best practices for minimizing link loss

The "link margin" or the "power budget" of the link is a measure of signal powergain or loss expressed in decibels (dB). Maintaining a healthy link budget is criticalto establishing a reliable and stable network.

Follow these best practices for minimizing link loss:v Stay well within the maximum cable distance calculated for the link.v Apply typical or worst-case values during loss calculations.v Use the highest grade cabling components for the application to be supported.v Match the cable type with the wavelength, bandwidth, and distance to be

supported; do not mix cable types within a link.v Inspect loss ratings of all cabling components during the selection process.v Record loss measurements for horizontal and vertical cable runs during

installation.


v Become familiar with how to quickly determine the link budget and link loss ofselected sections of the cabling.

v Account for power loss associated with future repairs and expansion.v Do not stress the cables.v Prototype a link with anticipated maximum cable distance and selected

components—and then take measurements to calculate the actual link loss

Attenuation on LWL connections

In the datacenter environment, there may be 8 Gbps or 4 Gbps LWL transceiversthat are connected to 2 Gbps LWL transceivers using single-mode fiber over shortdistances. Such connections need to be optically engineered because there is apossibility that the transmit power of the 8 Gbps / 4 Gbps LWL transceivers maysaturate the receiver of 2 Gbps LWL transceivers and cause CRC errors.

This discussion does not apply to 16 Gbps transceivers since connections between16 Gbps and 2 Gbps transceivers is not supported.

Refer to Table 23 for the typical specifications of maximum transmit and receivepower of LWL transceivers. This information is also available in the informationtechnology industry standard "Fibre Channel – Physical Interface-4 (FC-PI-4)"document.

Table 23. Specifications of LWL 10km transceivers

LWL SFP/SFP+ 2GFC 4GFC 8GFC

Power, Tx (max) dB -3 -1 +0.5

Power, Rx (max) dB 0 or -3 1 N/A N/A1 The maximum receive power specifications of some 2 Gbps LWL 10km transceivers canvary from 0dB to -3dB. However, most 2 Gbps 10km transceivers specify a maximumreceive power of 0dB.

It is important to check the maximum receive power of the 2 Gbps LWLtransceiver in the manufacturer's datasheet.

Without taking into account connector and fiber losses, the transmit power of 8Gbps / 4 Gbps LWL transceivers may be observed to overdrive the -3dB maximumreceive power of 2 Gbps LWL transceivers. If the maximum receive power of the 2Gbps LWL transceiver is 0dB, a 4 Gbps LWL transceiver with a -1dB transmitpower will not overdrive the 2 Gbps transceiver. Although some 8 Gbps LWLtransceivers may reduce their transmit power to 4 Gbps levels, this may stilloverdrive a 2 Gbps LWL transceiver.

Best Practice for LWL connections – Optically engineer along-distance connection

It is always a good practice to optically engineer a long-distance connection. Mostlink issues caused by SFP incompatibility can be solved either by use of 4 GbpsLWL transceivers or use of 8 Gbps LWL transceivers that employ rate select.

2G LWL SFP maximum receive power

The IBM SAN b-type 8 Gbps and 16 Gbps directors and switches use the latesthigh bandwidth Fibre Channel technology and auto-negotiate to 16 Gbps, 8 Gbps,4 Gbps, or 2 Gbps based on the link data rate capability of the attached transceiver.

Appendix B. Troubleshooting link errors 63

Negotiation to 1 Gbps is not supported. Since 8 and 16 Gbps equipment is moresensitive, the existing cable plant may require additional attention to cable careafter upgrading from 2 or 4 Gbps fibre. In a few cases, the Tx power of the switchcan be higher than the connected equipment. In nearly all of those cases, there isenough attenuation in the existing cable plant so as not to require additionalattenuation. The common 2 Gbps SFP Rx maximum power levels are listed inTable 24 and can be used as a quick method to relieve concerns of over saturation.
