Table 6 describes the power supply LED patterns and the recommended actions for those patterns.
Determining the status of a blower assembly
Complete the following steps to determine the status of a blower assembly.
1. Check the LED indicators on the blower assembly (see the following figure). The LED patterns
may temporarily change during POST and other diagnostic tests; for information about how to
interpret the LED patterns, refer to
Table 7 . The Brocade DCX 8510-4 has two blowers. Be sure
to check each module.
2. Check the blower assembly status using the fanShow command.
The status for each blower assembly displays OK, Absent, or Faulty. The RPM of each fan in the
assembly is also provided. If a blower assembly displays absent or faulty, contact the Brocade
DCX 8510-4 supplier to order replacement parts. Both physically absent or faulty could also be
the result of the power supply not being properly seated.
Figure 16 shows the blower assembly.
