The System Has Intermittent Failures; The System Led Or Diagnostic Leds Are Not On And No Error Messages Appear; Power Goes Off On The Server And Does Not Come Back On - HP Integrity rx1620 Operation Manual

12. If there are no obvious errors, reflash the BMC firmware. Refer to
instructions.
13. If the system will still not boot, it may be necessary to replace the base unit.

The system has intermittent failures

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.
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.
3. Display and examine the system event log (SEL) and forward progress log (FPL) for further
information relating to warning or fault indication.
4. Make sure that the system fan assemblies are fully seated.
5. Verify that the server is plugged into a power source that is within specifications described
on the label of the power supply.
6. Make sure that the internal SCSI chain is terminated and that termination is not enabled on
any of the drives. Note that with LVD SCSI, termination is provided in the cable.
7. Check that the processors are installed in the correct sockets and that terminators are installed
in all unused sockets.
8. Reseat the main memory DDR DIMMs.
9. If date and time or customer settings are being cleared, the system board battery may need
to be replaced.

The system LED or diagnostic LEDs are not on and no error messages appear

If the server does not work (with no LEDs illuminated) and no error messages appearing, check
the following:
1. Make sure that all cables and the AC power cord are plugged into their proper receptacles.
2. Make sure that the AC outlet is working. If the server is plugged into a switched
multiple-outlet box, make sure that the switch on the outlet box is turned on.
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 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.
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.
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
pairs.

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

When certain critical conditions exist, the server shuts down all power.
