The System Has Intermittent Failures - HP Integrity rx2620 User's & Service Manual

Troubleshooting
Possible Problems
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. This
information is also presented in the SEL.
NOTE
Step 3. Display and examine the SEL and Forward Progress Log (FPL) for further information relating to
warning or fault indication.
Step 4. Use the BMC command line interface (cli) to cycle the server power, cli>pc off, cli>pc on. This
may also be accomplished by the PC command (pc -cycle -nc) of the iLO MP.
Step 5. Remove all power from the server by disconnecting the AC power cord(s), wait at least twenty
seconds, then reconnect the power cords and turn the server back on to see if the failure can be
cleared.
Step 6. Check server memory for possible problems. This may also be accomplished by the info mem
command of the EFI.
Step 7. Check server processors for possible problems. This may also be accomplished by the info cpu
command of the EFI. This may also be accomplished by the SS command of the iLO MP.
Step 8. Check the boot order with the Boot Configuration menu.
Step 9. If the server will still not boot, it may be necessary to replace the base unit.

Step 1. Examine the display panel LEDs for warning or fault indications. The server 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.
NOTE
Step 3. Display and examine the SEL and FPL for further information relating to warning or fault
indication.
Step 4. Make sure that the server fan assemblies are fully seated.
Step 5. Verify that the server is plugged into a power source that is within specifications described on the
label of the power supply.
Step 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.
Step 7. Check that the processors are installed in the correct sockets and that terminators are installed in
all unused sockets.
Step 8. Reseat the main memory DDR DIMMs.
