Troubleshooting is based on observation of server status indications and error messages, and by
reviewing system event logs. You can observe the LED indicators on the front and rear of the server.
Error messages appear on local and remote consoles. System history (console, event, and history
logs) is available through the iLO 3 MP, and is accessed through the console. Additional information
about troubleshooting is available on the CD provided with the server.
Installation troubleshooting using the server power button
The server power button on the front panel operates differently depending on how long the button
is pressed, and on what the system is doing when the button is pressed. You must be aware of the
uses to properly troubleshoot the system.

If the server is off, and power is not connected to the 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
flashes 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 pressed, 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 issues during installation are usually related to the installation process. If the server does
not power on, view the LED indicators on the power supply rear panels and perform the following:
If the DC power LED on the power supply on the rear panel of the server is lit, power is
available to the server.
If the DC power LED is not lit, the server is either in standby power mode, or an issue may
have occurred. Re-seat the power supply. If the issue persists, remove and re-seat the board
within the server. If the issue still persists, replace the power supply or the power supply
interface board.
