5. Contact Brocade Technical Support for the replacement of WWN cards. Brocade support will request
the partner or OEM to send WWN cards from FRU inventory to the nearest Brocade Support office to be
reprogrammed. Brocade Support will require that the Supportsave data were taken in the previous
step so that the replacement cards can be reprogrammed prior to shipping to the partner or your site.
If Brocade support has determined that both WWN cards need replacing, you must replace both WWN
cards as a matched pair.
Hot-swap replacement
You may replace one WWN card assembly at a time with the system powered on using the following steps
to avoid interruption of system operation.
About this task
Use this procedure if Brocade Customer Support has determined that a WWN card needs replaced and
you have received replacement cards. These procedures require that you use the wwnrecover utility.
Procedure
1. Remove the defective WWN card assembly using procedures under "Removing the WWN card and
bezel" on page 153.
Removing a WWN card assembly will result in RASlog messages indicating that a WWN card cannot
be detected. Since the system will be in a degraded state, replace the WWN card as soon as possible.
2. Install the replacement WWN card assembly into the empty slot using the following steps:
a) Holding the card assembly by its edges with both hands along its length, slide it into the chassis
slot.
b) Push with your thumb on the end of the assembly to fully seat it into the backplane connector.
c) Use a Phillips screwdriver to tighten the captive screw and secure the card assembly to the
chassis.
Note: Be sure that the captive screws are tightened. If they are not tightened, high pressure from
fan operation may unseat cards from chassis connectors.
3. Verify that the WWN card is correctly connected by noting if the LEDs on the card reflect the status of
the components.
4. Address any issues flagged by any RASlog EM-1220 and EM-1222 messages that display for the new
card before proceeding.
Note: To avoid invalid WWN data, errors, and operating problems, issues relating to data recovery on
new WWN cards must be resolved at this point before proceeding. If EM-1220 messages indicate
that IP addresses on installed WWN cards do not match, follow instructions in the message to
recover the IP address so that both cards use the same address.
5. Determine the active CP blade by entering the haShow command.
