Replacing the WWN bezel (logo plate) and WWN card
The World Wide Name (WWN) cards contain fully redundant circuits and normally do not require
replacement. Two WWN cards are located beneath the WWN bezel (logo plate).
Allow approximately 20 minutes to replace a WWN card. The following items are needed to replace
a WWN card:
•
ESD grounding strap
•
#2 Phillips screwdriver (required only for some versions of the WWN card)
•
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)
How to determine whether or not to replace a WWN card
Before replacing a WWN card, verify that the replacement is necessary. Any of the following events
can indicate that the card requires replacement:
•
Status LEDs on the WWN bezel not reflecting the actual status of the components
•
Power or Status LEDs on WWN card (beneath logo plate) indicate a problem
•
Problems viewing or modifying the data stored on the WWN card, see
•
