3. Make sure that the server is turned on (the power-on light should be green and
the fans should be on).
4. Turn the server off, wait at least twenty seconds, then turn the server back on to
see if the failure can be cleared.
5. Make sure that all boards are installed properly and the processors are installed
in the correct slot. They must be seated firmly in their slots and any cables must
be connected firmly.
6. If the server stopped working after you installed a new board, remove the board
and power on the server. If your server now works, check the installation
instructions received with the new board for correct installation method. If the
new board is preventing the server from powering on, a serious electrical problem
is likely.
7. If the server still does not work, remove all boards and options that you have
installed (do not remove the hard drives) and power on the server.
8. Add the boards and options one at a time to determine which one is causing the
problem.
9. If you have added any memory, make sure that the DDR DIMMs are seated
properly in the board. Also check the DDR DIMM configuration, and that the DDR
DIMMs are matched quads.

The Server Powers Off but Does Not Restart

When certain critical conditions exist, the server shuts off all power.
The critical conditions that can shut off the server include:
critical temperature fluctuations or changes
voltage problems (external AC line)
power supply failure
If the server powers off, and before you try a restart, do the following:
1. Examine the display panel LEDs for warning or fault indications. The server LED
flashes yellow with a warning indication and flashes red with a fault indication.
2. Examine the four diagnostic LEDs for indications of specific warning or fault
indications. The diagnostic LEDs present patterns that categorize the source of
the warning or fault.
NOTE:
MP. The diagnostic LEDs are disabled.
3. Display and examine the SEL and FPL for further information about warning or
fault indication.
4. Make sure power is getting to the server. Plug a known working device into the
power outlet.
5. Check for proper ventilation for the server. The server should have at least three
inches of space around the front and rear for proper airflow when installed in a
rack.
NOTE:
6. Check the server specifications and make sure the environmental temperature
and voltage are within the specified guidelines.
7. Monitor the server to make sure you are not experiencing further temperature
and voltage problems.
