Operating the SAN Director 2/128 WWN Card To determine the status of the WWN card: 1. Check the LED indicators on the WWN bezel (see Figure 19) and verify that they reflect the actual status of the components. The WWN bezel covers the WWN card and allows its LEDs to shine through. The LEDs on the WWN bezel provide a consolidated view of the port card status, CP card status, and power supply status. The LED patterns may temporarily change during POST and other diagnostic tests; for information about how to interpret the LED patterns, refer to Table 10. 2. Check the WWN card status using the commands listed in Table 10. Difficulty retrieving or modifying this data could indicate a WWN card failure.
