HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

1. Observe the LED indicators on the WWN bezel and verify that they reflect the actual status
of the components. The WWN bezel covers the WWN cards and allows its LEDs to shine
through. The LEDs on the WWN bezel provide a consolidated view of the port, CP, and CR
blade status (see Table 15 (page 78)).
If a blade slot has a filler panel installed, the corresponding LEDs on the WWN card do not
illuminate.

NOTE: If a status LED on the WWN bezel flashes, the power LED on the WWN bezel also
flashes, for increased visibility.
2. Verify the WWN card status using the commands listed in Table 16 (page 78). Difficulty
retrieving or modifying this data could indicate a WWN card failure.
Table 16 Commands identifying the WWN card status
CommandsWWN card information
wwn, chassisShowWWN values
chassisShowData about the chassis and WWN card
ipAddrShow, ipAddrSetEthernet and FC IP address information for the CP blades
historyShow, historyLastShowHistory log information

3. Look up the error message indicating the status of the WWN unit (see Table 17 (page 78)).
Enter the chassisShow command to determine the status of the WWN unit.
