7.
Install the power supply into another power supply slot and identify whether the power supply
can operate correctly. If the power supply operates correctly, the original power supply slot
might be damaged. If the power supply does not operate correctly, go to the next step.
8.
Install a new power supply of the same model into the same slot, and connect it to the same
power input end. If the new power supply can operate correctly, the old power supply has failed.
You must replace the old power supply.

If the issue persists, contact H3C Support.
NOTE:
After you turn off the power feed to a power supply, the input and output status LEDs on the power
supply will stay on for a while.
Fan tray failure
WARNING!
The fan trays are hot swappable. Ensure electricity safety when you hot swap a fan tray.
CAUTION:
• To ensure adequate heat dissipation, make sure all fan trays are present when the gateway is
operating. If a fan tray fails, keep the failed fan tray in place until a new fan tray is ready for
replacement.
• Before powering on the gateway, make sure all fan tray slots are installed with fan trays correctly.
Symptom
•
The fan tray status LEDs on the SEM indicate a fan tray failure.
M9000-AI-E8 gateway—The FAN OK LED on the SEM is off and the FAN FAIL LED is on.
If the fan trays on an M9000-AI-E8 gateway are operating correctly, the FAN OK LED on the
SEM is on and the FAN FAIL LED is off.
M9000-AI-E16 gateway—The FAN LED on the SEM is steady red.
If the fan trays on an M9000-AI-E16 gateway are operating correctly, the FAN LED on the
SEM is steady green
•
The LEDs on a fan tray indicate that the fan tray is faulty.
M9000-AI-E8 gateway—The OK LED is off and FAIL LED is on.
When a fan tray is operating correctly, its OK LED is on and FAIL LED is off.
M9000-AI-E16 gateway—The OK/FAIL LED is steady red.

Solution
To resolve the issue:
1.
If both LEDs are off, verify that the power supplies are operating correctly. For more information,
see
"Power supply
2.
Verify that the air inlet and outlet vents of the chassis are not blocked. If they are blocked, clean
them to keep good ventilation. If you install air filters, remove the air filters, clean them, and
install them again.
3.
Verify that the fan tray is fully seated. You can remove the fan tray and then install it again.
4.
Verify that the empty interface module slots and power supply slots are installed with filler
panels. If not, install filler panels for them to guarantee good ventilation.
