Troubleshooting

• Interval 3 — If the calculated value of the PWM duty cycle is less than or
equal to 100%, the FC firmware will send a signal to the fan to operate at
the set duty cycle.
• Interval 4 — If the calculated value of the PWM duty cycle is higher than
100%, the FC firmware will send a signal to the fan to operate at 100%
duty cycle and trigger sled throttling.
• Interval 5 — If the calculated value of the PWM duty cycle is less than or
equal to 100%, the FC firmware will send a signal to the fan to operate at
the set duty cycle.
• Sixth interval — If the calculated value of the PWM duty cycle is still
higher than 100% again, the FC firmware will send a signal to the fan to
operate at 100% duty cycle and trigger sled throttling for 1 hour.
To troubleshoot the enclosure fan modules:
1
Locate the faulty fan module in the back of the enclosure.
2
Each fan module has indicators that identify a faulty fan. See Figure 1-5.
3
Remove the fan module. See "Removing a Fan Module" on page 207.
4
Examine the blades for debris. If debris is present, carefully remove it.
5
Reseat the fan module. See "Installing a Fan Module" on page 208.
6
If none of the fan indicators show a fault LED and the blade do not power
on, log into the BMC web interface and check for status messages.
7
If the problem is not resolved, install a new fan.
8
If the new fan does not operate, see "Getting Help" on page 289.
