F-4 HP ProLiant DL145 Server User Guide
Table F-4: BIOS Beep Codes
Number of Beeps Troubleshooting Action
1, 2 or 3 Reseat the memory, or replace with known good modules.
4-7, 9-11 Fatal error indicating a serious problem with the system.
Remove add-in card to eliminate the possibility of interference.
If the beep codes are generated even when all other expansion cards are
absent, the motherboard has a serious problem.
If the beep codes are not generated when all other expansion cards are
absent, one of the add-in cards is causing the malfunction. Insert the cards
back into the system one at a time until the problem happens again. This will
reveal the malfunctioning add-in card.
8 If the system video adapter is an add-in card, replace or reseat the video
adapter. If the video adapter is an integrated part of the system board, the
board may be faulty.
Problems After Initial Startup
After the server has passed POST, errors may still be encountered, such as an inability to load
the operating system. Use Table F-5 to troubleshoot server installation problems that occur
after the initial startup.

NOTE: If the server is rebooting repeatedly, be sure that the system is not restarting due to a
Watchdog Timer power up caused by another problem. Watchdog is similar to ASR on ProLiant servers
300, 500, and 700 series.
