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.
This document provides the following information:
•Time and Items Required on page -4
•Location of Components on page -4
•Verifying Necessity of Replacement on page -6
•Replacing the WWN Card on a SilkWorm 12000 Running Fabric OS v4.1 on page -7

•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.

11. Display and record the manufacturer serial numbers: enter the chassisshow command (see Figure 27), then copy the
command output into the “config-miscinfo.txt” file.
Note: In versions of Fabric OS prior to v4.1, the chassisshow command uses “Brocade Part Number” and “Brocade
Serial Number” where “Factory Part Number” and “Factory Serial Number” are shown here.
The chassisshow command lists up to two serial numbers:
•“Factory Serial Num” is listed under “Chassis/WWN Unit 1” (see Figure 27). If the current WWN card is the
original card, this serial number is the same as the chassis serial number provided on the bar code sticker inside
the door of the chassis.
•“Serial Num” is listed under “Chassis/WWN Unit 1”. If a “Serial Num” value displays, contact the switch
provider to determine whether this serial number should be modified after the new WWN card is installed.

12. Record the chassis serial number provided on the bar code sticker inside the door of the chassis.
