Error Code Handling

Error Code Handling

The error code displayed on the fault diagnosis LED on the front panel of a server indicates a hardware fault of the server. This topic describes the error codes and the procedure of rectifying faults.

Context

When a key component is faulty, the server fault diagnosis LED displays an error code to facilitate fault locating.

Servers RH1288 V3, RH2288 V3, RH2288H V3, RH5885 V3, 5288 V3, 1288H V5, 2288H V5, 2488 V5, 2488H V5, and 5885H V5 provide the fault diagnosis LED. Generally, the fault diagnosis LED is located on the front panel of the server. For details about its position, see the user guide of the server you use.

Procedure

  1. View the error code on the fault diagnosis LED.
  2. Log in to the iBMC WebUI of the server, and locate the alarm based on the error code.
  3. Rectify the fault.
  4. After the fault is rectified, check that the error code is not longer displayed on the fault diagnosis LED.
