Offline troubleshooting programs are available on the resource CD that is shipped with the
server. To troubleshoot the server, you must be familiar with the Offline Diagnostics Environment
(ODE) which runs in the Extensible Firmware Interface (EFI). Descriptions and user information
about offline troubleshooting tools are available at

If the server is off, and power is not connected to server power supplies, pressing the power
button has no effect.
If the server is off, and power is connected to server power supplies, the front panel power LED
blinks at a 1 Hz rate. In this state, standby power is available to server circuits, but main power
is off.

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 system is doing when the button is pressed. You must be aware
of its uses to properly troubleshoot the system.
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. Re-seat the power supply. If the problem persists, remove and re-seat the board
