SilkWorm 12000 WWN Card Replacement Procedure 3 of 41

Overview

The SilkWorm 12000 world wide name (WWN) card is highly reliable and contains fully redundant circuits. It should not

usually require replacement under normal operating conditions. Before replacing the card, make sure you actually need to

replace it by referring to the information provided under Verifying Necessity of Replacement on page 6. Contact your support

provider if you have any questions about whether the WWN card requires replacement. If the WWN card does fail, the

SilkWorm 12000 can continue operating until the new WWN card is installed if the configuration is not modified, no hardware

components are replaced, and the SilkWorm 12000 is not rebooted.

The WWN card is located on the non-port side of the chassis underneath the WWN bezel (see Figure 1 on page 4).

This procedure requires a command line interface (CLI) to the SilkWorm 12000. The CLI can be either a telnet session or a

serial console session; instructions are provided for both. The steps required to replace the WWN card depend on the version

of Fabric OS; one procedure is provided for Fabric OS v4.1.0 or later, and another procedure is provided for earlier versions.

Note: If a serial console is used, all commands must be entered through the active CP card unless otherwise indicated. For

command details, refer to the Fabric OS Reference.

•Verifying Necessity of Replacement on page -6

•Reference Information for the frureplace Command on page -35

•Reference Information for the fruinfoset Command on page -37

•Reference Information for the chassisshow Command on page -39

All the instructions required to replace the WWN card are provided in this document. Additional related information can be

found in the following documentation:

•SilkWorm 12000 Hardware Reference Manual

•Diagnostic and System Error Message Reference

Caution If the Fabric OS version is earlier than v4.1.0, the SilkWorm 12000 must be powered off to replace the

WWN card. Before replacing the card, determine the version of Fabric OS installed and ensure the

correct procedure is followed when performing the replacement.

DO NOT power cycle or reboot the SilkWorm 12000 or replace the CP cards or port cards until the

WWN card is verified as functional or a replacement WWN card is installed. If any of these events

happen while the WWN card is failed or uninstalled, the configuration information is lost, and it will be

necessary to reconfigure the SilkWorm 12000 after installing the new WWN card.

Disassembling any part of the WWN card voids the part warranty and regulatory certifications. The

WWN card contains no user-serviceable parts.

Time and Items Required

For Fabric OS v4.1, allow approximately 20 minutes to replace the WWN card. For earlier versions of Fabric OS, allow

approximately 60 minutes.

The following items are needed to replace the WWN card:

•ESD (electrostatic discharge) grounding strap

•#2 Phillips screwdriver (only required for some versions of the WWN card)

•Required if a serial console session is used: A serial cable and a workstation computer with a terminal emulator

application (such as HyperTerminal for Windows systems or TIP for Solaris systems)

Verifying Necessity of Replacement

Before replacing the WWN card, verify the replacement is necessary. Ensure the current card is firmly seated when performing

troubleshooting steps, and contact your support provider if you have any questions about whether the card should be replaced.

Any of the following events may indicate that the card requires replacement:

•Visible mechanical damage to the WWN card

•Any of the Status LEDs on the WWN card do not reflect the actual status of the components

•Problems viewing or modifying the data stored on the WWN card (see Data Stored on the WWN Card, below)

•Error messages regarding WWN units #1 or #2 (see Messages that May Indicate WWN Card Failure, below)

Data Stored on the WWN Card

The data listed in Table 2-1 is stored on the WWN card. Difficulty retrieving or modifying this data may indicate WWN card

failure.

Messages that May Indicate WWN Card Failure

If the error log or serial console display error messages that indicate problems with WWN units #1 or #2, the WWN card may

have failed. WWN units #1 and #2 correspond to information specific to the WWN card and are displayed by the chassisshow

command.

Note: WWN units #1 and #2 do not correspond to the WWNs for logical switches 0 and 1.

For more information about error messages, refer to the Diagnostics and System Error Message Reference.

SilkWorm 12000 WWN Card Replacement Procedure 7 of 41

Replacing the WWN Card on a SilkWorm 12000

Running Fabric OS v4.1

Note: For more information about specific commands, refer to the Fabric OS Reference.

1. Open a CLI session (telnet or serial) to Switch 0 and log in as admin. The default password is “password”.

Instructions are provided for both a telnet session and a serial console session.

Logging in by Telnet

Telnet to the IP address of Switch 0.

Figure 3 Opening a Telnet Session to Switch 0 and Logging in as Admin

Logging in by Serial Console

To log in by serial console, you must first determine which CP card is active by entering the hashow command through

either a serial or telnet session, and then connect to the active card.

a. Connect the serial cable to the active CP card. If the active card is not known, connect to the card in slot 5 (CP0).

b. Disable any serial communication programs running on the workstation (such as synchronization programs).

c. Insert one of the serial cables into the terminal serial port on the CP card in slot 5 (the terminal serial port is the

second serial port from the top of the CP card). See Figure 1 on page 4.

d. Connect the other end of the serial cable to a serial port on the workstation. If necessary, the adapter on the serial

cable can be removed to allow for a serial RJ45 connection.

e. Open the terminal emulator application and configure as described below.

•For Windows 95, 98, 2000, or NT, enter the parameters provided in the following list:

Parameter Value

Bits per second 9600

Databits 8

Parity None

Stop bits 1

Flow control None

•For most UNIX systems, enter the following string at the prompt:

tip /dev/ttyb -9600

f. When the terminal emulator application stops reporting information, press <Enter> and log in as admin (the default

password is “password”), then enter “0” to log into Switch 0 (see Figure 4).

g. Enter the hashow command to determine which CP card is active (see Figure 5).

h. If CP0 is not the active CP card, connect the serial cable to CP1 and log in as admin to Switch 0 (see Figure 6).

Figure 6 Opening a Serial Console Session to CP1 and Logging in as Admin

2. Enter the version command to verify the firmware version (see Figure 7).

•If the firmware is Fabric OS v4.1 or later, continue with this procedure.

•If the firmware is an earlier version, follow the procedure provided under Replacing the WWN Card on a

SilkWorm 12000 Running a Version of Fabric OS Prior to 4.1 on page 13.

Figure 7 Sample Output for the version Command in Fabric OS v4.1

3. Enter frureplace wwn and wait for the phrase “Do you wish to continue [y/n]?” to display, then enter “y” (see Figure 8).

4. Verify that the following has occurred:

•The phrase “Please enter the word ‘continue’...” displays in the CLI (see Figure 8). Do NOT enter continue; the

mechanical replacement must be completed first.

•All the LEDs on the WWN card turn off.

These events indicate that data has been backed up and the card can now be replaced.
