Preparing for WWN card replacement
About this task
If the WWN cards require replacement, complete the following steps. Follow electrostatic discharge (ESD)
precautions.
Procedure
1. Open a Telnet session to the device and log in to the active CP blade as admin. The default password
is "password".
2. Verify that you are logged in to the active CP blade. Run the
haShow
command to determine the active
CP blade.
3. Run the supportSave command on the active CP blade to capture all settings. These settings will be
referenced to verify the settings have been correctly programmed after WWN replacement.
4. Run the following commands on the device before replacing the cards so that the data can be verified
after the replacement:
v licenseidshow
v ipaddrshow
v
switchname
v chassisname
v
wwncardshow ipdata
v chassisshow (look at the WWN and chassis information at the bottom)
