Determining the status of a fan
Complete the following steps to determine the status of a fan.
1. Check the LED indicators on the fan (refer to Figure 18 ). The LED patterns may temporarily
change during POST and other diagnostic tests; for information about how to interpret the LED
patterns, refer to
Table 16 . The Brocade VDX 8770-8 has up to four fans. Be sure to check
each module.
2. Check the fan status using the show environment fan {rbridge-id rbridge-id | all} command.
Refer to Table 15 for possible results from this command. The RPM of each fan is also
provided. If a fan displays absent or faulty, contact the Brocade VDX 8770-8 supplier to order
replacement parts. Both physically absent or faulty could also be the result of the fan not being
properly seated.
NOTE
You can also use the show system command.
Figure 18 on page 58 shows a fan module.
