Wwn Led Patterns; Commands Identifying The Wwn Card Status - HP A7533A - Brocade 4Gb SAN Switch Base Hardware Reference Manual

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 36).
If a blade slot has a filler panel installed, the corresponding LEDs on the WWN card do not light
up.
