xxii SAN42B-R Installation, Service, and User Guide

Chapter 1. Overview of the SAN42B-R switch

The IBM System Storage SAN42B-R switch is intended as a platform for Fibre Channel over IP (FCIP). This enables transmission of Fibre Channel data over long distances 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. The switch can operate independently or in a fabric containing multiple extension switches.

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 not support FCIP connectivity with any other products including the SAN06B-R and the 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 provide high bandwidth FCIP tunnel and lossless failover resiliency. In addition, each FCIP circuit supports four QoS classes (Class-F, High, Medium and Low Priority), each as a TCP connection.

v ARL feature meets minimum bandwidth guarantee for each tunnel while

making the full utilization of the available network bandwidth without adverse throughput performance impact at high traffic load.

v Hardware-based compression delivers the ability to maximize throughput over

lower bandwidth links in the wide area network, optimizing the cost efficiencies of FCIP. The SAN42B-R compresses FC frames before they are encapsulated into FCIP packets.

v Key protocol features are enabled in the FCIP implementation to optimize

performance of Extension over IP networks, including FX8-24 and WAN Optimized TCP (WO-TCP), 9K jumbo frame and end-to-end Path MTU auto discovery.

v Hardware-based IPsec supports mix of secure and non secure tunnels on the

same Ethernet port, jumbo frames, and VLAN tagged connections. The IPsec function 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 IP WAN.

v FCIP HCL (Hot Code Load) provides In-service firmware upgrade for

supporting 24/7 nonstop business operations.

v Built-in WAN link tester generates traffic over an IP connection to test for

maximum throughput, congestion, loss percentage, out of order deliver, latency, and other network conditions. It helps determine the health of a WAN link before 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.

– Flow generator generates FC frames for a defined flow with default or

custom size and pattern and sent across FCIP tunnel to help validate end-to-end network setup and configuration.

v Fabric OS delivers distributed intelligence throughout the network and enables a

wide range of value-added applications.

Attention: This product may not be certified in your country for connection by any means whatsoever to interfaces of public telecommunications networks nor to be used in a public services network. Further certification may be required by law prior to making any such connection. Please contact IBM for information.

6 SAN42B-R Installation, Service, and User Guide

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 9

v “Setting up the switch as a standalone unit” on page 10

v “Installing in an EIA cabinet” on page 10

v “Initial setup of the switch” on page 21

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

Site preparation and installation requirements

The following conditions are required to ensure correct installation and operation of 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 following electrical 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

52.

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

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental 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 intake

of exhaust air.

v Airflow requirements outlined in “Environmental requirements” on page 51

must be met.

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

operating.

Cabinet requirements

For successful installation and operation of the switch in a cabinet, ensure that the following 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 a branch 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, using cable channels on the sides of the cabinet or patch panels to minimize cable management. 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 bend radius.

v If you are using ISL Trunking, consider grouping cables by trunking groups. The

cables used in trunking groups must meet specific requirements, as described in the Fabric OS Administrator’s Guide.

v For easier maintenance, label the fiber optic cables and record the devices to

which 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 can damage the optic fibers.

v Record port and cable connections using a table such as Appendix C, “Cable

routing table,” on page 59.

Items required for installation

The following items are required for installing, configuring, and connecting the SAN42B-R for use in a network and fabric.

Chapter 2. Installing and configuring the switch 9

Setting up the switch as a standalone unit

Attention: Refer to “Safety notices and labels” on page xi before starting 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 rubber feet on the switch help prevent the switch from sliding off the supporting surface.

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 is correctly set. For instructions on how to cable and configure the switch, and how to set the IP address, see “Initial setup of the switch” on page 21.

Installing in an EIA cabinet

The switch can be installed so that the port side is either flush with the front posts or recessed with the non-port side flush with the rear posts. A recessed position allows a more gradual bend in the fiber optic cables connected to the switch and less interference in the aisle at the front of the rack.

Note: The illustrations in the installation instructions show a 1U device. The SAN42B-R is a 2U device but the installation instructions are the same.

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

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

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

Time required

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

Providing power to the switch

DANGER

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 service loop 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 connected to a power source. Each power supply has two LEDs, one for AC status and one for DC status. Both LEDs turn green within one second of power being applied. The power status LED on the port side of the switch turns green as soon as either power supply LED is green. The status LED is amber only until FOS is loaded and then it turns green. The status LED is green while POST is running.

Attention: Power is supplied to the switch as soon as the first power supply is connected to a power source. There are no switches on the power supplies to turn the power on and off.

3. After POST is complete, verify that the switch power and status LEDs on the

left 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 serial connection. If you need to know the serial port pinouts, refer to Table 20 on page

54.

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 of RS-232, remove the adapter from the end of the serial cable and insert the exposed RJ-45 connector into the RJ-45 serial port 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 application as 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 string at 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 Dynamic Host 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 the Fabric 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 default gateway address from the DHCP server. The DHCP client can only connect to a DHCP server that is on the same subnet as the switch. If your DHCP server is not on the same subnet as the switch, use a static IP address.

Setting a static IP address

Chapter 2. Installing and configuring the switch 23

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 dotted decimal notation as prompted.

switch:admin> ipaddrset Ethernet IP Address [192.168.74.102]:

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

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

3. Complete the rest of the network information as prompted. (IPv4 format shown

in 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 ipAddrShow

command at the prompt.

Changing the switch name and chassis name

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

Complete the following steps to change the chassis name and then the switch name.

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 command

switch: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 by Web Tools. Ensure that the switch is not being modified from any other connections during the remaining tasks. The Ethernet management port also supports 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.

24 SAN42B-R Installation, Service, and User Guide

The default domain ID is 1. If the switch is not powered on until after it is connected to the fabric and the default domain ID is already in use, the domain ID for the new switch is automatically reset to a unique value. If the switch is connected to the fabric after it has been powered on and the default domain ID is already in use, the fabric segments. To find the domain IDs that are currently in use, enter the fabricShow command on another extension switch in the fabric.

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 previous

extension switch, if still available).

Domain: (1..239) [1] 3

e. Complete the remaining prompts or press Ctrl+D to accept the remaining

settings 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 operation does not depend on the date and time; a switch with incorrect date or time values still functions properly. You can synchronize the local time of the principal or primary fabric configuration server (FCS) switch to that of an external Network Time 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 specifies the new date and time enclosed in double quotation marks. this operand is optional; if omitted, the current date and time is displayed. Date and time are specified as a string in the mmddhhmmyy format. The syntax uses the following values:

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 are interpreted as 2000 to 2037.

Chapter 2. Installing and configuring the switch 25

Synchronizing local time with an external source

Complete the following steps to synchronize the local time of the principal or primary 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 switch can access. This argument is optional; by default, the value is "LOCL".

swSAN42BR:admin> tsclockserver 192.168.126.60 Updating 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 following procedure 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 -8,0 For Central Standard Time, enter tsTimeZone -6,0 For Eastern Standard Time, enter tsTimeZone -5,0

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

Setting the time zone needs to be done only once, because the value is stored in nonvolatile memory. For U.S. time zones, use Table 5 to determine the correct parameter 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 the portcfgpersistentenable command to enable the ports.

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

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

Installing SFP+ and QSFP transceivers and connecting cables

Complete the following steps to install SFP+ transceivers and to connect cables to the switch. The process for installing QSFP transceivers is similar. The transceivers may already be installed in the switch as shipped. If this is the case, you can either just 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. Only transceivers purchased from IBM are supported. The use of transceivers that are not supported may cause data loss or cause the product to malfunction. For a listing 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 the port 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 recommends connecting 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 correct orientation. Transceivers should slide easily into the port if aligned correctly.

Chapter 2. Installing and configuring the switch 27

v Do not remove the covers. Removing the covers of the laser product

could result in exposure to hazardous laser radiation. There are no serviceable parts inside the device.

v Use of the controls or adjustments or performance of procedures

other than those specified herein might result in hazardous radiation exposure.

(C026)

Installing 16 Gbps SFP+ transceivers

Attention: With increasing speeds of optical connections, the cleanliness of the connections assumes greater importance in ensuring maximum performance and error free transmission. Due to the tighter tolerances associated with state of the art optics, levels of contamination that were acceptable at lower speeds may not be at higher speeds. While IEC Standard 61300-3-35 specifies a set of guidelines for trouble free performance, most issues can be avoided by adhering to the following best 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. IBM also 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 transceiver until the latching mechanism clicks. Cables are keyed so that they can be inserted in only one way. If a cable does not slide in easily, ensure that it is correctly oriented.

Attention: Take care not to bend the SFP+ pull tab. Do not insert a cable intended for an mSFP transceiver into a regular SFP+ transceiver. You may damage the cable.

4. Transceivers are keyed so that they can only be inserted with the correct

orientation. Insert the cable/transceiver into the port, using the pull tab to help push the transceiver into the port. If it does not slide in easily, ensure that it is correctly oriented.

Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or reset, and during which the LEDs flash different colors.

Complete the following steps to determine whether POST completed successfully and whether any errors were detected.

1. Verify that the LEDs on the switch indicate that all components are healthy

(LED patterns are described in Table 6 on page 34 and Table 7 on page 36. If one or more LEDs do not display a healthy state, complete these steps.

a. Verify that the LEDs are not set to "beacon" (this can be determined through

the switchShow command or Web Tools). For information about how to turn beaconing on and off, refer to theFabric OS Administrator's Guide or the Web Tools Administrator's Guide.

b. Follow the recommended action for the observed LED behavior, as shown

in Table 6 on page 34 and Table 7 on page 36.

2. Verify the diagShow command displays that the diagnostic status for all ports in

the switch is OK.

3. Review the system log for errors. Errors detected during POST are written to

the system log, which is viewed using the errShow command. For more information about this command, refer to the Fabric OS Command Reference. For information about specific error messages, refer to the Fabric OS Message Reference.

Switch maintenance

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

Diagnostic tests

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

The tests are implemented by command, either through a Telnet session or through a serial console connection to the switch. Some tests require the ports to be connected by external cables to allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable. Some tests require loopback plugs.

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

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

Chapter 4. FRU replacement

Attention: Read “Safety notices and labels” on page xi before removing or installing any components. Follow ESD precautions (see “ESD precautions” on page xvii whenever handling FRUs.

The field replaceable units (FRUs) in the SAN42B-R can be removed and replaced without special tools. The switch can continue operating during the FRU replacement 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 part of the initial switch installation and configuration. Power supply and fan FRU removal and replacement steps are described in the following procedures. The chassis replacement procedure is to be completed by IBM Service personnel only, and cannot be completed while the switch is operating.

Power supply removal and replacement

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

Attention: Disassembling any part of the power supply voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the power supply. Because the cooling system relies on pressurized air, do not leave either of the power supply slots empty longer than two minutes while the switch is operating. 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, and actions 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 functioning correctly. 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> psshow Power Supply #1 is OK Airflow Direction : Portside Intake (Forward) Power Supply #2 is OK Airflow Direction : Portside Intake (Forward) 2498:admin>

Time and items required

Replacing a power supply in the switch requires less than two minutes to complete.

To replace a power supply in the switch, you need a new power supply that has the same part number as the power supply being replaced.

Attention: Do not force the installation. If the power supply does not slide in easily, ensure that the power supply is correctly oriented before continuing.

5. Plug the power cord into the power supply to power on the unit. If the power

circuit was on before the replacement, the power supply will immediately attempt to power up.

6. Verify that the LEDs on the new power supply display steady green while the

switch is operating (refer to Table 7 on page 36). If the LEDs are not steady green, ensure that the power supply is securely installed and seated properly.

7. Optionally, use the command line interface (CLI) to enter the psShow command to display the status. You can also use the chassisShow command. The power supply status can also be viewed using the Web Tools application.

Fan removal and replacement

The switch has three fans as displayed in Figure 3 on page 5. The Fabric OS identifies the fan locations from left to right as fan #3, fan #2, and fan #1 as viewed from the nonport side of the switch.

Attention: Disassembling any part of the fan voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the fan. Because the cooling system relies on pressurized air, do not leave any of the fan slots empty longer than two minutes while the switch is operating. If a fan fails, leave it in the switch until it can be replaced. Maintain all three fans in operational condition to provide redundancy.

Appendix B. Troubleshooting link errors

IBM SAN b-type directors and switches use the latest high 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 and the speed supported by the switches and directors. Negotiation to 1 Gbps is not supported unless 4 Gbps FC transceivers are used. As the 8 and 16 Gbps channel is more sensitive to the condition of the existing multimode and single mode cable plant, it is very important to minimize connector reflections and maintain an acceptable link loss budget.

This section provides link troubleshooting advice on fault isolation and provides guidance in the following areas:

v Dust and dirt contamination

v Link loss

v Attenuation on LWL connections

Fault isolation

Since a job loss issue can be caused by a variety of problems, it is important to employ a systematic fault isolation process to remedy the issue. Note that job losses do not necessarily result from link errors. They may also be due to:

v Configuration issues

v Networking overload

v Failures on storage device, switch, or server

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

Whenever CRC errors are discovered on a particular link, it is easy to jump to the conclusion 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 the propagated error to where it originated.

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

To determine the original failing link, the observable CRC error needs to be tracked 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 propagated from link 3, which in turn originated from link 2.

Once the original failing link (link 2) has been determined, the two connecting ports of that link need to be checked for the following errors:

v Encoder errors

v Disparity errors

v Invalid transmission words

The port that displays any of the above errors is the cause of the link issue, which can be caused by dust or dirt in the connectors or fiber, an insufficient link loss budget, 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 the connectors and fiber. 8 and 16 Gbps links are more prone to such issues while lower 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 isolation process, the receive power of the transceiver sitting in that port needs to be determined. An abnormally low receive power usually means that the physical link is dirty.

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

For better accuracy, it is advisable to use a power meter to measure the actual receive power of the link. If you are experiencing excessive bit errors and the receive power of the transceiver is abnormally low, it is recommended that you:

v Re-seat the transceivers for the failing link

v 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 power gain or loss expressed in decibels (dB). Maintaining a healthy link budget is critical to 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 of

selected sections of the cabling.

v Account for power loss associated with future repairs and expansion.

56 SAN42B-R Installation, Service, and User Guide

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 transceivers that are connected to 2 Gbps LWL transceivers using single-mode fiber over short distances. Such connections need to be optically engineered because there is a possibility that the transmit power of the 8 Gbps / 4 Gbps LWL transceivers may saturate the receiver of 2 Gbps LWL transceivers and cause CRC errors.

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

Refer to Table 22 for the typical specifications of maximum transmit and receive power of LWL transceivers. This information is also available in the information technology industry standard "Fibre Channel – Physical Interface-4 (FC-PI-4)" document.

Table 22. 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

The maximum receive power specifications of some 2 Gbps LWL 10km transceivers can vary from 0dB to -3dB. However, most 2 Gbps 10km transceivers specify a maximum receive power of 0dB.

N/A N/A

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

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

Best Practice for LWL connections – Optically engineer a long-distance connection

It is always a good practice to optically engineer a long-distance connection. Most link issues caused by SFP incompatibility can be solved either by use of 4 Gbps LWL 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 latest high 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. Negotiation to 1 Gbps is not supported. Since 8 and 16 Gbps equipment is more sensitive, the existing cable plant may require additional attention to cable care after upgrading from 2 or 4 Gbps fibre. In a few cases, the Tx power of the switch

Appendix B. Troubleshooting link errors 57

can be higher than the connected equipment. In nearly all of those cases, there is enough attenuation in the existing cable plant so as not to require additional attenuation. The common 2 Gbps SFP Rx maximum power levels are listed in Table 23 and can be used as a quick method to relieve concerns of over saturation.
