a WWN card:
•
Electrostatic discharge (ESD) grounding strap
•
#2 Phillips screwdriver (required only for some versions of the WWN card)
•

emulator application (such as HyperTerminal for Windows systems or TIP for Solaris systems)
Verifying the need for replacement

can indicate that the card requires replacement:

Power or Status LEDs on WWN card (beneath logo plate) indicate a problem
•

•

Preparing for the WWN card replacement
If the WWN card requires replacement, complete the following steps.
ATTENTION
Follow ESD precautions (see “ESD Precautions” in your chassis manual).
1. Open a Telnet session to the chassis and log in to the active CP as admin. The default
password is “password”.
2. Verify that you are logged into the active CP. Run the haShow command to determine the active
CP.
3. Run the supportsave command on the active CP to capture all settings.
4. Contact Brocade Technical Support for a replacement WWN card. Technical Support will
require the supportsave data collected in the previous step so that a replacement can be
programmed prior to shipping to your location.
DO NOT execute the frureplace command. The command will no longer be functional beginning
with the release of Fabric OS 7.0.0c, but users with earlier versions of the Fabric OS should
also NOT run the command.
