Table 1-3 Diagnostic front panel LEDs and audible codes (continued) Activity Beeps Possible Cause Recommended Action 3. Replace the power supply. 4. Replace the system board. Red Power LED flashes five 5 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Pre-video memory error. CAUTION: To avoid damage to the DIMMs or the system board, you must unplug the workstation power cord before attempting to reseat, install, or remove a DIMM module. 1. Reseat DIMMs. 2. Replace DIMMs one at a time to isolate the faulty module. 3. Replace third-party memory with HP memory. 4. Replace the system board. Red Power LED flashes six 6 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Pre-video graphics error. For systems with a graphics card: 1. Reseat the graphics card. 2. Replace the graphics card. 3. Replace the system board. For systems with integrated graphics, replace the system board. Red Power LED flashes seven 7 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. System board failure (ROM detected failure prior to video). Replace the system board. Red Power LED flashes eight 8 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Invalid ROM based on bad 1. checksum. Reflash the system ROM with the latest BIOS image. See the "Boot Block Emergency Recovery Mode" section of the Service and Technical Reference Guide on the Documentation and Diagnostics CD for more information. 2. Replace the system board. Red Power LED flashes nine 9 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. System powers on but is unable to boot. 1. Check that the voltage selector, located on the rear of the power supply (some models), is set to the appropriate voltage. Proper voltage setting depends on your region. 2. Replace the system board. 3. Replace the processor. ENWW Basic troubleshooting 21

Activity
Beeps
Possible Cause
Recommended Action
3.
Replace the power supply.
4.
Replace the system board.
Red Power LED flashes five
times, once every second,
followed by a two second
pause. Beeps stop after fifth
iteration but LEDs continue
until problem is solved.
5
Pre-video memory error.
CAUTION:
To avoid damage to the
DIMMs or the system board, you must
unplug the workstation power cord before
attempting to reseat, install, or remove a
DIMM module.
1.
Reseat DIMMs.
2.
Replace DIMMs one at a time to isolate the
faulty module.
3.
Replace third-party memory with HP
memory.
4.
Replace the system board.
Red Power LED flashes six
times, once every second,
followed by a two second
pause. Beeps stop after fifth
iteration but LEDs continue
until problem is solved.
6
Pre-video graphics error.
For systems with a graphics card:
1.
Reseat the graphics card.
2.
Replace the graphics card.
3.
Replace the system board.
For systems with integrated graphics, replace the
system board.
Red Power LED flashes seven
times, once every second,
followed by a two second
pause. Beeps stop after fifth
iteration but LEDs continue
until problem is solved.
7
System board failure
(ROM detected failure
prior to video).
Replace the system board.
Red Power LED flashes eight
times, once every second,
followed by a two second
pause. Beeps stop after fifth
iteration but LEDs continue
until problem is solved.
8
Invalid ROM based on bad
checksum.
1.
Reflash the system ROM with the latest BIOS
image. See the “Boot Block Emergency
Recovery Mode” section of the
Service and
Technical Reference Guide
on the
Documentation and Diagnostics CD
for more
information.
2.
Replace the system board.

times, once every second,
followed by a two second
pause. Beeps stop after fifth
iteration but LEDs continue
until problem is solved.
9
