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

Chapter 1. Introducing the SAN24B-4 Express switch

The IBM System Storage SAN24B-4 Express is a cost-effective and highly-scalable 1, 2, 4, or 8 Gbit/sec switch, designed for small to mid-sized businesses. It runs on the Fabric Operating System (Fabric OS) and is compatible with other IBM switches, which enables seamless connectivity into heterogeneous SAN environments. This switch is a dual purpose device that you can use either as a full-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 all SAN connectivity. Because the switch is scalable, you can use it as a foundation switch for a small storage area network (SAN) and continue to use it as a building block as the SAN grows.

This chapter provides the following information:

v “Features and functions of the switch” v “Supported connectivity” on page 2 v “Port side of the switch” on page 2 v “Nonport side of the switch” on page 3 v “Additional port activation” on page 3 v “ISL Trunking groups” on page 3 v “Supported optional features” on page 4

Features and functions of the switch

The switch provides the following features and functions: v 1U chassis–The chassis can be installed as a standalone unit or mounted in a

standard Electronic Industries Association (EIA) 48.26 cm (19 in.) cabinet.

v One built-in fixed power unit (not field-replaceable) v Three built-in fans (none are field-replaceable). The switch is cooled by a

redundant fan configuration, which allows continued operation with a single fan failure.

v On-demand scaling of 8 to 24 8 Gbit/sec ports v ASIC technology supporting 1, 2, 4 and 8Gbit/sec auto-sensing Fibre Channel

ports.

v Ability to operate as either a full-functioned switch or an NPIV access gateway. v RJ45 Ethernet management port that in conjunction with EZSwitchSetup,

supports switch IP address discovery and configuration.

v Uses EZSwitchSetup wizard for setup and basic configuration. v Single motherboard design with a 667 MHz PowerPC

Instruction Set Computer (RISC) CPU with integrated peripherals.

v Offers forward and backward compatibility with IBM System Storage SAN

switch models, 1, 2, 4 and 8 Gbps auto-sensing capability, as well as Advanced Fabric Services and management tools.

v Enables interoperability between IBM System Storage b-type and m-type SAN

switches and directors.

v Inter-Switch-Link Trunking (licensable) enables up to eight ports (at 1G, 2G, 4G,

or 8G speeds) between a pair of switches to be combined to form a single,

440EPx Reduced

logical ISL switch with a speed of up to 64 Gbits/sec (128 Gbits/sec full duplex) for optimal bandwidth utilization and load balancing.

v Advanced Zoning. v Intelligent management and monitoring with Web Tools, Fabric Watch, and

Performance Monitor.

v Adaptive Networking Services uses network intelligence to anticipate congestion

and to dynamically make adjustments in the fabric so that application traffic continues to flow

v Dynamic Path Selection (DPS) optimizes fabric-wide performance and load

balancing by automatically routing data to the most efficient available path in the fabric.

v Light emitting diodes (LEDs) to indicate system power, system status, Ethernet

speed and link status, and port status.

Supported connectivity

Specific details on supported operating systems, servers, and devices, storage products attachability, SAN connectivity products, and configuration options can be found in the interoperability matrices at the following web site: www.ibm.com/servers/storage/support/san.

Port side of the switch

Figure 1 shows the port side of the switch. All LEDs are on the port side of the switch: the nonport side is used to allow the free flow of air. The switch enclosure has forced-air cooling, with the fans pushing the air from the nonport side of the chassis through the enclosure, exhausting to the port side. For a complete description of the locations and interpretations of these LEDs, see “Interpreting LED activity” on page 21.

Nonport side of the switch

The nonport side of the switch is used solely for air flow. There are no features on this side.

Supported fabric configurations

The switch is supported as an edge device in fabrics of up to 239 switches.

Additional port activation

The switch can be purchased with 8, 16, or 24 licensed ports. As your needs increase, you can activate unlicensed ports by purchasing and installing the additional 8 port activation feature. After it has been installed, the license appears under the licenseShow command as Ports on Demand license.

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

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

After you have installed the license keys, you must enable the ports. You can do so without disrupting switch operation by using the portEnable command on each port individually. Alternatively, you can disable and reenable the switch to activate all ports simultaneously.

To install the additional port activation license, you can either use the supplied license key or generate a license key. Typically the switch is shipped with a paper pack 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 groups

The switch supports Interswitch Link (ISL) Trunking as a licensed feature. When this feature is enabled, create Trunked groups of up to 8 contiguous ports. This means 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 and color-coded within groups of eight to indicate which ports you can combine into trunked groups.

Chapter 1. Introducing the SAN24B-4 Express switch 3

Figure 2. Trunking groups

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

Note: ISL Trunking is optional software that allows you to create trunking groups

of ISLs between adjacent switches. For more information about trunking, refer to the Fabric OS Administrator’s Guide.

Supported optional features

The switch supports the following optional software, which you can activate by purchasing 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 the Fibre Channel standard 10 km by optimizing the internal switch buffers to maintain performance on ISLs at distances up to 500 kilometers.

v Fabric Watch–monitors mission-critical switch operations. This feature is

designed to enable real-time proactive awareness of the health, performance, and security of each switch. It automatically alerts network managers to problems and 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 priority

connections to obtain the bandwidth necessary for optimum performance, even in congested environments.

v Advanced Performance Monitor–provides Performance Monitoring capability to

help identify end-to-end bandwidth usage by host/target pairs and is designed to provide information for capacity planning.

v Trunking Activation–designed to enable Fibre Channel packets to be efficiently

distributed across multiple Inter-Switch connections (links) between two SAN b-type fabric switches, while preserving in-order delivery. ISL Trunking is supported between any of the supported 2, 4, or 8 Gbps b-type models. Both SAN b-type fabric switches must have ISL Trunking activated.

Chapter 1. Introducing the SAN24B-4 Express switch 5

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

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 surface v 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 into a slide-rail rack, you can mount the chassis to slide from either the port side or the non-port side.

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

Attention: When you enable Access Gateway mode, you disable the ability for the SAN24B-4 to operate as a switch. Access Gateway mode and switch mode are mutually 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. Changing between Access Gateway and Switch modes is a data disruptive operation. It is strongly recommended that you disable the switch from the command line interface before enabling or disabling Access Gateway mode.

This chapter provides the following information:

v “Items included with the switch” v “Installation and safety considerations” on page 8 v “Installing a stand-alone switch” on page 9 v “Installing the switch into an EIA cabinet” on page 9 v “Recommendations for cable management” on page 15 v “Configuring the switch” on page 16

Items included with the switch

The following items are included with the standard shipment of the switch. When you open the packaging, verify that these items are included in the package and that no damage has occurred during shipping:

v One SAN24B-4 switch v An accessory kit that contains the following items:

– Serial cable with an RJ-45 connector – One grounded 1.8 m (6 ft.) country-specific power cord – Four rubber feet, required for setting up the switch as a stand-alone unit – SFP transceivers (quantity depending upon features ordered) – IBM System Storage SAN24B-4 Installation, Service, and User Guide (this

– EZSwitchSetup CD – One LC wrap plug

Installation and safety considerations

Use this section to prepare your site for a safe and successful installation.

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

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

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

Electrical considerations

To 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 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

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 to product installations in racks or cabinets.

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.

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

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 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,

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’s

weight limits or unbalance the cabinet in any way.

v Secure the cabinet to ensure stability in case of unexpected movement, such as

an earthquake.

Installing a stand-alone switch

To 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 7

2. 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 of the feet.

b. With the adhesive side against the chassis, place one rubber foot in each

indentation 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 is correctly set. For instructions on how to set the IP address, see “Configuring the switch” on page 16.

Installing the switch into an EIA cabinet

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

Attention: Refer to “Rack safety” on page xx for danger and caution notices related 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 of the cabinet.

Chapter 2. Installing and configuring the switch 9

v To allow the non-port side of the switch to slide out the cool-air side of the

cabinet. In this installation, the port side of the switch is set 7.62 cm (3 in.) back from the edge of the cabinet, allowing a more gradual bend in the fiber optic cables.

Time required

Approximately 30 minutes

Items required

You need the following items to install the switch in a slide-rail rack:

v Straight slot screwdriver v Rack space: 1 EIA unit of rack space, 48.3 cm (19 in.) wide, and 60.96 cm (24 in.)

deep

v One power cord that is provided with the switch v One power outlet v Rack mount kit

Attention: Use the exact screws specified in the procedure for use with the switch chassis. Using screws longer than 3/16 in. can damage the switch. The different types of screws are listed in Table 3 on page 11.

Note: Make sure that you tighten all screws used in this procedure.

Installation instructions

To install the switch in a slide-rail rack that meets EIA standards, use the following procedure.

Note: These procedures use parts that are included in the rack-mount kit. These

parts are listed in Table 3 on page 11. The installation procedure cross-references the items in this table. Be sure to use the referenced parts when you perform each step.

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

DANGER

Note: Do not connect the switch to the network until you perform one of the

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.

following 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.

Chapter 2. Installing and configuring the switch 15

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. 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 bend radius.

v If you are using Brocade 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 fasteners to secure and organize fibre optic cables. Do not

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

Configuring the switch

You must configure the switch to ensure correct operation within a network and fabric. For instructions about how to configure the switch to operate in a fabric that contains switches from other vendors, refer to the Fabric OS Administrator's Guide.

For more information about the commands used in this procedure, refer to the Fabric OS Command Reference Manual.

v “Using the EZSwitch setup (optional)” v “Providing power to the switch” v “Creating a serial connection” on page 17 v “Setting the switch IP address” on page 17 v “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 to give it power and a basic configuration. If you are going to use the switch in a single-switch setup, you can use EZSwitchSetup to complete the basic configuration. See the EZSwitchSetup CD included with the accessory kit for more information. You can also use the SAN24B-4 Quick Start Guide. If you do not want to use EZSwitch Setup, use the instructions in following sections.

Providing power to the switch

To 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 loop of 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 is supplied 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 to green. The switch usually requires from 1 to 3 minutes to boot and complete POST.

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

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

Creating a serial connection

You will perform all basic configuration tasks in this guide using a serial connection. To create a serial connection to the switch, complete the following steps:

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 the adapter on the end of the serial cable and insert the exposed RJ-45 connector into 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 as follows:

v In a Windows

Bits per second 9600

Databits 8

environment), and configure the application

Flow control None

v In a UNIX environment, type the following string at the prompt:

tip /dev/ttyb -9600

If ttyb is already in use, 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 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 DHCP

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 the 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

1. 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 dotted decimal notation as prompted.

Ethernet IP Address: [192.168.74.102]

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

Chapter 2. Installing and configuring the switch 17

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.

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 time

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

Setting the date

1. 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 12 v dd is the date; valid values are 01 through 31 v HH is the hour; valid values are 00 through 23 v MM is minutes; valid values are 00 through 59 v 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 as 2000-2069)

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

Setting time zones

You can set the time zone for a switch by name. You can specify the setting using country and city or time zone parameters. If the time zone is not set with the new options, the switch retains the offset time zone settings. The tsTimeZone command also includes an option to revert to the prior 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. The tsTimeZone command allows you to perform the following tasks:

v Display all of the time zones supported in the firmware v 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

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 the default setting.

v System services that have already started will reflect the time zone changes only

after 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 must perform 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 the value 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 and how to change the time zone to US/Central.

switch:admin> tstimezone Time Zone : US/Pacific switch:admin> tstimezone US/Central switch:admin> tstimezone Time Zone : US/Central

The following procedure describes how to set the current time zone using interactive 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 NTP

You can synchronize the local time of the principal or primary fabric configuration server (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 the principal or primary FCS switch has its time synchronized with at least one external NTP server. The other switches in the fabric will automatically take their time from the principal or primary FCS switch.

Chapter 2. Installing and configuring the switch 19

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

For more information on using an NTP server, and IPv6 considerations, see the Fabric 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 the switch must be able to access. The second ntp2 is the second NTP server and is optional. The operand “<ntp1;ntp2>” is optional; by default, this value is LOCL, which uses the local clock of the principal or primary switch as the clock 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 rest will 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 server every 64 seconds.

switch:admin> tsclockserver LOCL switch:admin> tsclockserver "132.163.135.131" switch:admin> tsclockserver

132.163.135.131

switch:admin>

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

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net" Updating Clock Server configuration...done. Updated with the NTP servers Changes to the clock server value on the principal or primary FCS switch

are 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 23 v “POST and boot specifications” on page 25 v “Interpreting POST results” on page 26 v “Switch FRU units” on page 26 v “Maintaining the switch” on page 26 v “Managing the switch” on page 30

Powering the switch on and off

See Chapter 2, “Installing and configuring the switch,” on page 7 for initial setup instructions before powering the switch on for the first time. Once the switch has been 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 the switch, remove the power cord from the power source.

Interpreting LED activity

System activity and status can be determined through the activity of the LEDs on the switch. All LEDs are located on the port side of the switch. There are three possible LED states: no light, a steady light, and a flashing light. The steady lights and flashing lights can be green or amber. The LEDs flash either of these colors during boot, POST, or other diagnostic tests.

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

The success or failure results of the diagnostic tests that run during POST can be monitored 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.

In 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.

Chapter 3. Operating the switch 25

Interpreting POST results

POST 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 that occur during POST are listed in the error log.

To determine that POST completed successfully and whether or not any errors were 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 and interpretation of LED patterns. If one or more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to “beacon”; use the switchShow command to detect if beaconing is active.

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

3. Review the switch system log for errors. Any errors detected during POST are written 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, refer to the Fabric OS System Error Message Reference Manual.

Switch FRU units

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

Maintaining the switch

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

Installing SFPs

The switch only supports Brocade-branded SFPs. If you use an unqualified SFP, the switchShow command output will show the port in an Mod_Inv state. Fabric OS will 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 on page 27

Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.

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

The correct position to insert an SFP into the upper row of ports is with the gold edge down. The correct position to insert an SFP into the lower row of ports is with the gold edge up.

Removing SFP modules

To remove an SFP:

1. Press and hold the cable release B, as shown in section 1 of Figure 10

2. Remove the cable from the SFP, as shown in section 2.

3. Pull the bail (wire handle) D in section 3 to release the SFP.

4. Grasping it by the bail, gently but firmly pull the SFP (C in section 4) out of

the port. Attention: If the SFP you are removing does not have a bail, use a small

implement such as a screwdriver to press the release trigger beneath the port. Non-bailed SFPs can be damaged by the removal process and are not recommended. Refer to the interoperability matrix at the following web site: www.ibm.com/servers/storage/support/san for a list of supported SFPs and devices.

5. Repeat this procedure for the remaining ports, as required.

Testing a port, SFP, and fiber cable

The PortLoopbackTest command is used to verify the functional operation of the switch by sending frames from the port "N" transmitter and looping them back into 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 use those results to isolate the problem to either the port or the SFP and cable combination. If a port is faulty, the switch will need to be replaced. If the port is not faulty, the problem is either with the SFP or the cable.

With this command, only one frame is transmitted and received at a time. No external 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 at some value.

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

8. Repeats Steps 2 through 7 for all ports until one of the following conditions are 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 passes are requested, seven different data types are used in the test. If eight passes are requested, the first seven frames use unique data types, and the eighth is the 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 with either the cable or SFP.

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

Chapter 3. Operating the switch 29

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

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

not reappear.

Diagnostic tests

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

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

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

Managing the switch

You can use the management functions built into the switch to monitor the fabric topology, port status, physical status, and other information to help you analyze switch performance and to accelerate system debugging. The switch automatically performs power-on-self-test (POST) each time it is turned on. Any errors are recorded in the error log. For more information about POST, see “POST and boot specifications” 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 any of the management options listed in Table 8.
