To determine the status of a WWN card: 1. Check 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 16). If a blade slot has a filler panel installed, the corresponding LEDs on the WWN card do not light up.

No action required NOTE: If a status LED on the WWN bezel flashes, the power LED on the WWN bezel also flashes, for increased visibility. 2. Check the WWN card status using the commands listed in Table 17. Difficulty retrieving or modifying this data could indicate a WWN card failure.
