Server Does Not Power On

The server Power button on the front panel operates differently depending on how long the

button is held, and on what the server is doing when the button is pressed. You must be aware

of its uses to properly troubleshoot the server.

NOTE: If the server is off, and power is not connected to server power supplies, pressing the

Power button has no effect.

Power problems during installation are usually related to the installation process. If the server

does not power on, check the LED indicators on the power supply rear panels and follow these

steps.

• If the AC power LED on the power supply on the rear panel of the server is lit, power is

available to the server.

• If the AC power LED is not lit, the server is either in standby power mode, or there is a

problem. Reseat the power supply. If the problem persists, remove and reseat the board

within the server. If the problem persists, replace the power supply or the power supply

interface board.

• If the console shows that the server is powered on, but server LEDs indicate that power is

off, remove and reseat connectors on the LED status board. If the problem persists, replace

the LED status board.

If the console shows that the server is not powered on (server is off), remove and reseat

connectors on the system board. If the problem persists, replace the power supply interface

board, or the system board.

Operating System Does Not Boot

If the operating system does not boot, but you are able to reach the BCH from either the main

disk partition or the CD, use the following tools to help solve the problem:

• Check the system logs and analyze any error messages.

• Offline Diagnostic Environment (ODE)
