Management System Troubleshooting

The Power indicator (green) is off.

No AC input

Check whether the AC input is abnormal.

PSU fault

Replace the PSU.

The Alarm indicator (yellow) is steady on.

Overtemperature protection

• The ambient temperature exceeds the upper threshold. Increase the cooling capacity of the smart cooling product.
• The air channel is blocked. Unblock it.

AC input overvoltage or undervoltage protection

Check whether the AC input is abnormal.

The Alarm indicator (yellow) is blinking.

PSU communication failure

1. Clean the connector in the rear of the faulty PSU.
2. If the fault persists, replace the ECC800-Pro subrack.

Monitoring module communication failure

The Alarm indicator (red) is steady on.

Output overvoltage protection

• If a single PSU is locked out, disconnect the AC input from the PSU, and then power on the PSU again after the indicator turns off. If the fault persists, replace the PSU.
• If multiple PSUs are locked out, remove all PSUs and reinstall them one by one to locate the faulty ones. Then replace faulty PSUs.

No output due to a PSU fault

Replace the faulty PSU.

1

The Run indicator (green) is off.

There is no AC input.

If the green indicators on PSUs are steady on, the power input to the system is normal. Otherwise, rectify power grid faults.

The monitoring module is faulty or not securely installed.

Reinstall the monitoring module. If the fault persists, replace the monitoring module.

2

RJ45 power output indicators turn off (involved ports: AIDI_1 - AIDI_5, COM1-COM4, and DO).

The corresponding power ports have no output.

Energize corresponding power ports over the WebUI or network management system.

The corresponding power ports are short-circuited.

Check whether the connected load is short-circuited. If yes, eliminate the short circuit.

3

The ALM indicator (red) is steady on.

Faults and alarms are generated.

View active alarms on the WebUI and clear them one by one.
