Troubleshooting
WARNING: To reduce the risk of electric shock or damage to the equipment, before
opening access panels to reseat components, power down the server, and then
disconnect the power cord.
Table 5-3: Server Does Not Have Video
Possible Reasons The Next Step
Video cable may not be properly connected.
Switches may not be correctly set on the system
board.
If an optional video board was installed, the
monitor cable may not be correctly connected.
The monitor may be connected to the wrong
video connector.
Expansion boards or DIMMs may not be
properly connected or seated.
1. Be sure that the monitor has power and
that the monitor cable is securely
connected. If more than one video adapter
is installed, make sure that the monitor is
connected to the correct video board.
2. Be sure that the monitor is functional by
connecting it to a known working server.
3. Be sure that the switch settings on the
system board are correctly set.
4. Power down the server. Reseat all
expansion boards, DIMMs, processors, and
PPMs. Reseat all cable connections.
5. Restart the server.
6. Listen for audible indicators, such as a
series of beeps. A series of beeps indicates
the presence of a POST error message.
7. Monitor the diagnostic LEDs on the system
board for failure conditions.
8. If these steps do not correct the problem,
contact an authorized service provider for
further technical support.
Table 5-4: 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.
