Knowledge Article: ID B00000072: POST watchdog triggered

Description

The Power-On-Self-Test (POST) watchdog in the specified blade server has been triggered.

Causes

The POST events occur when a system does not succesfully complete POST.

Implications

Resolutions

Perform these steps:

1. From the advanced management module Web interface, look at the LEDs for the blade server (click Monitors and then click LEDs) and check for any errors. If an error has occurred, refer to the Hardware Maintenance Manual and Troubleshooting Guide for the specified blade server type to resolve the error. The Hardware Maintenance Manual and Troubleshooting Guide is available on the Web.
   
   
2. If you added options to the blade server, reseat those options. Otherwise, reseat the blade server.
   
   
3. If the blade server is an HS20 or an HS40 blade server, listen for any beep codes that may occur when the blade server reboots. Refer to the Hardware Maintenance Manual and Troubleshooting Guide for more information about resolving beep codes.
