Impact on the System

The power supply abnormality may lead to power supply insufficiency on the router and cause the board to reset due to power supply insufficiency. This indirectly affects services, and the problem needs to be resolved.

Possible Causes

The switch 1 on a power module is off.

Procedure

1. Check whether switch 1 on the power panel is closed.

If switch 1 is not closed, go to Step 2.
If switch 1 is closed, go to Step 3.

2. Close switch 1 and check whether the alarm is cleared.

If the alarm is cleared, go to Step 5.
If the alarm persists, go to Step 3.

3. Replace the power module.

Power off the faulty power module before replacing it. Then check whether the alarm is cleared.

If the alarm is cleared, go to Step 5.
If the alarm persists, go to Step 4.

4. Collect trap, log, and configuration information, and contact technical support.

5. End.
