Solution
To resolve the problem:
1.
Execute the display fan command to display the operating states of the fan tray.
<H3C> display fan
Slot 1
If the fan tray is in Absent state, go to step 2.
If the fan tray is in Fault state, go to step 3.
2.
Remove and reinstall the fan tray to make sure the fan tray is securely installed. Then execute the
display fan command to verify that the fan tray has changed to Normal state. If the fan tray
remains in Absent state, replace the fan tray.
3.
Execute the display environment command to display temperature information. If the temperature
continues to rise, put your hand at the air outlet to verify that air is being exhausted from the air
outlet. If there is no air being exhausted from the air outlet, remove and reinstall the fan tray. Then
execute the display fan command to verify that the fan tray has changed to Normal state. If the fan
tray remains in Fault state, replace the fan tray.
If there is no new fan tray, power off the switch to avoid damage caused by high temperatures.
If there are cooling measures to maintain the switch operating temperature below 60°C (140°F),
the switch can be used temporarily.

If the problem persists, contact H3C Support.
