Fan Tray Failure - H3C S12500X-2L Installation Manual

1. Verify that the power supply model is compatible with the switch.
The PSR1800-56A and PSR1800-56D power supplies are compatible with the switch.
2. Remove and reconnect the power cord to verify that the power cord is connected securely.
3. Replace the power cord.
4. Remove and reinstall the power supply to verify that it is installed securely.
For more information, see "Installing power supplies."
5. Verify that the power source 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
over-current, output over-voltage, input under-voltage, or over-temperature.
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.
