2. 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 the LEDs to shine through (see Figure 28 on page 79). The LEDs on the
WWN bezel provide a consolidated view of the port, CP, and CR blade status
(see Table 13).

Note: If a blade slot has a filler panel installed, the corresponding LEDs on the
WWN card do not light up
Note:
If a status LED on the WWN bezel flashes, the power LED on the WWN
bezel also flashes, for increased visibility.
