Power Goes Off On The Server And Does Not Come Back On - HP Integrity rx1600 Operation And Maintenance Manual

Troubleshooting
Possible Problems
Step 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.
Step 6. If the server stopped working after you installed a new board, remove the board and turn 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, it is likely to have a serious electrical problem.
Step 7. If the server still does not work, remove all boards and options that you have installed (do not remove the hard disk
drives) and turn on the server.
Step 8. Add the boards and options one at a time to determine which one is causing the problem.
Step 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 pairs.

Power goes off on the server and does not come back on.

When certain critical conditions exist, the server shuts down all power.
The critical conditions that may shut down the server are:
• 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:
Step 1. Examine the display panel LEDs for warning or fault indications. The system LED will be flashing yellow with a
warning indication and flashing red with a fault indication.
Step 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.
Step 3. Display and examine the system event log (SEL) and forward progress log (FPL) for further information relating
to warning or fault indication.
Step 4. First check to make sure power is getting to the server. Plug a known working device into the power outlet.
Step 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
Step 6. Check the system specifications and make sure the environmental temperature and voltage are in the specified
guidelines.
Step 7. Monitor the system to make sure you are not experiencing further temperature and voltage problems.
