5. Install replacement WWN card assemblies 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 device slot.
b) Push with your thumb on the end of assembly to fully seat into the backplane connector.
c)
Use a #1 Phillips screwdriver to tighten the captive screw and secure the card assembly to the chassis.
NOTE
Be sure that captive screws are tightened. If not, high pressure from fan operation may unseat cards from chassis
connectors.
6. Power on the device and wait for five minutes for the device to boot.
7. Verify that new WWN cards are correctly connected by checking LED function. For details on LED operation, refer to
Interpreting WWN card LEDs on page 109.
NOTE
The LEDs may take up to two minutes after WWN card installation to begin functioning.
8. Resolve any issues flagged by RASlog EM-1220 and EM-1222 messages that display for the new card(s) before proceeding.
NOTE
Issues relating to data recovery on new WWN cards must be resolved at this point before proceeding to avoid invalid
WWN data, errors, and operating problems.
9. Determine the active CP blade by entering the haShow command.
10. On the active CP blade, run the wwnrecover command and specify WWN 2 card for recovery when prompted in wwnrecover
output messages. Refer to Using the wwnrecover utility on page 171 for more information on this command.
11. If wwnrecover messages prompt for a system reboot, reboot both CP blades to ensure the system is running with valid WWN
card data.
12. Verify the new card settings by running the following commands and comparing the output with the original supportsave data:
• licenseidshow
• ipaddrshow
• switchname
• chassisname
• wwncardshow ipdata
• chassisshow (look at the WWN and chassis information at the bottom)
13. Run the switchcfgpersistentenable command to persistently enable each logical switch, that was disabled before removing the
WWN card(s):
switch:FID128:root> switchcfgpersistentenable
Switch's persistent state set to 'enabled'
14. Install the WWN bezel on the chassis.
a) Orient the bezel on the chassis.
b) Insert and tighten both screws using a Phillips screwdriver.
15. Pack faulty WWN card assemblies in the packaging provided with the replacement cards, and return them to Brocade Support
for failure analysis (FA).
