Solution
To resolve the issue:
1.
Verify that the power supply model is compatible with the router.
2.
Remove and reconnect the power cord to ensure that the power cord is connected securely.
3.
Replace the power cord.
4.
Remove and reinstall the power supply to ensure that it is installed securely.
For more information, see "Installing power supplies."
5.
Verify that the power supply system is supplying power at the acceptable voltage range.
6.
Verify that the total maximum output power of all power supplies exceeds the system power
consumption.
7.
Verify that the power supply does not have issues such as output short circuit, output
overcurrent, output overvoltage, input undervoltage, or overtemperature.
8.
Install the power supply in another empty power supply slot. If the power supply operates
correctly, the previous power supply slot is faulty. If the power supply does not operate correctly,
go to the next step.
9.
Install a correctly operating power supply of the same model in the same slot, and connect it to
the same power source. If the new power supply can operate correctly, the old power supply
has failed. Contact your sales agent or local service engineer to replace the old power supply.
10.
If the issue persists, contact H3C Support.
Fan tray failure
WARNING!
The fan trays are hot swappable. Ensure electricity safety when you hot swap a fan tray.
CAUTION:
•
For good cooling performance, install fan trays in all fan tray slots. When a fan tray fails, keep the
faulty fan tray in the chassis until a new fan tray is ready to be installed.
•
Before hot swapping a fan tray, make sure the remaining fan trays can provide sufficient cooling
for the router.
•
If multiple fan trays fail, do not remove the fan trays at the same time. Replace the fan trays one
after another and finish replacing a fan tray within 3 minutes.
•
Before powering on the router, make sure all fan tray slots are installed with fan trays correctly.
Symptom
The LEDs for the fan tray are in the following states:
•
On the MPU, the FAN LED is steady red.
•
On the fan tray, the OK/FAIL LED is steady red.
Solution
To resolve the issue:
1.
If all the LEDs are off, verify that the power supplies are operating correctly. For more
information, see "
."
2.
Execute the
display fan
command in any view to display the operating state of the fan tray
and rectify the fault. The command output displays the following information:
Whether the fan tray is present.
Airflow direction of the fan.
