Removing the WWN card
Allow approximately 20 minutes to remove or replace the WWN card. Obtain the following items:
• Electrostatic discharge (ESD) grounding strap
• #2 Phillips screwdriver (required only for some versions of the WWN card)
• The following is required if a serial console session is used: serial cable and a workstation
computer with a terminal emulator application (such as HyperTerminal for Windows systems or
TIP for Solaris systems)
This procedure requires CLI access to the Director via a telnet session or a serial console connection.
1. Open a telnet session and log into the active CP as admin. The default password is password.
NOTE: If a serial console is used, all commands must be entered through the active CP card unless
otherwise indicated. For command details, refer to the Fabric OS command reference manual.
