Verifying fan operation
About this task
Perform the following tasks to verify operation of a fan assembly:
Procedure
1. Check the LED indicators on the fan assemblies. The fan assemblies are located
on the nonport side of the device. The LED patterns may temporarily change
during POST and other diagnostic tests. For information on interpreting LED
patterns, refer to “Interpreting fan assembly LEDs” on page 82.
2. Check the fan assembly status using the following commands:
v fanShow - Displays the status for each fan assembly as OK, Absent, or Faulty.
The RPM of each fan in the assembly is also provided. If a fan assembly
displays absent or faulty, contact the device supplier to order replacement
parts. Both physically absent or faulty could also be the result of the fan not
being properly seated in the chassis slot.
v sensorShow - Displays current temperature and status of fan and power
supply sensors located in the device.
v
errShow
- Displays error log messages one at a time.
v errDump - Displays the entire system error log.
