The Card RUN/ALM Indicators and Power Module Indicators Are Off

The Card RUN/ALM Indicators and Power Module Indicators Are Off

Fault Description

The Card RUN/ALM indicators and power module indicators are all off, and the chassis cannot be powered on.

Possible Causes

  • Power cables are inserted into incorrect sockets, not the ones to which the power modules are connected.
  • Power cables are not securely connected to the sockets.
  • The power modules are faulty.

Troubleshooting Procedure

  1. Check power cable connections at the rear of the chassis to ensure that power cables are inserted to the sockets where power modules are installed. The following figure shows the mapping between power modules and power sockets.

    Power sockets at the rear and power module slots at the front have a one-to-one mapping. For example, if a power module is installed in slot PM1, a power cable must be inserted into socket 1.

  2. Ensure that the power cables are securely connected to the sockets.
  3. Replace the power modules with normal power modules of the same model. If the chassis is powered on, the original power modules on the chassis are faulty. Send the faulty power modules to Huawei for repair.
  4. If the chassis still fails to be powered on, contact technical support personnel.
