analysis (FA).
Removing the WWN card and WWN bezel (logo plate)
Two WWN cards located beneath the WWN bezel (logo plate). As you are facing the bezel on the non-port-side of the chassis, WWN 1
is located on the left side, and WWN 2 is on the right. When cards have been determined faulty and the replacement WWN cards have
been received, complete the following steps to remove the bezel and faulty WWN cards.
Follow electrostatic discharge (ESD) precautions. Wear a wrist grounding strap connected to chassis ground (if the chassis is plugged in)
or a bench ground.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
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 in to 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. If any problem occurs during the replacement, the
supportsave information will be important for solving the problem.
