3. Verify that the WWN card is correctly connected by noting if the LEDs on the card reflects 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

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. 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 by entering the haShow command.

6. On the active CP, run the wwnrecover command and specify the WWN card that you replaced

(WWN 2 or WWN 1) when prompted.

7. If wwnrecover messages prompt for a system reboot, reboot both CPs to ensure the system is

running with valid WWN card data.

8. Enter the hafailover command to force failover so that the standby CP becomes the active CP.

This command is necessary so that the correct IP address for the new card displays for the

ipaddrshow command. For more information on these commands, refer to the Fabric OS

Command Reference.

9. 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)

10.If replacing the second WWN card, repeat steps 1-11 for the other card.

11.Install the WWN bezel. Orient the bezel on the chassis. Insert and tighten the screws.

12.Pack faulty WWN cards in the packaging provided with the replacement cards, and return them to

Brocade Support for failure analysis (FA).

Power-down replacement

Use these procedures when you can interrupt system operation and replace one or both WWN cards

with the system powered down.

Use this procedure if Brocade Customer Support has determined that a WWN card needs replaced

and you have received the replacement card. These procedures require use of the wwnrecover utility.

NOTE

You can use this procedure if replacing one or both WWN cards, however you must use this

procedure if replacing both WWN cards. If Brocade support has determined that both WWN cards

need replaced, you must power-down the chassis, and then replace both WWN cards as a matched

pair. Obtain replacement cards through your Brocade product support representative.

Follow electrostatic discharge (ESD) precautions. Wear a wrist grounding strap connected to chassis

ground (if the chassis is plugged in) or a bench ground.
