Troubleshooting
Understanding the Diag LEDs
Chapter 11

Understanding the Diag LEDs
The Diag LEDs on the front panel of the Workstation can help you
identify specific problems with your Workstation:
•
During system start up, all four LEDs are green.
•
If a problem is detected, one or more of the LEDs changes color.
•
If no problems are detected during start up, all four turn off.
A list of possible combinations, an explanation of the problem, and
suggested solutions are listed in Table 11-1 on page 213.
The LED patterns are defined by:
•
R = Red
•
Y = Yellow
•
G = Green
•
●
= Off
Unless the LED pattern indicates that the BIOS is in recovery mode
(YR
●●
), or that BIOS recovery is complete (GR
●●
), you should:
1.
Flash the system BIOS and firmware. For complete instructions and
the latest BIOS and firmware versions, go to
www.hp.com/workstations/support
.
2.
Attempt the solutions given in Table 11-1 on page 213. Possible
solutions are listed in order of ease and probability. Follow the
solutions in sequence in sequence.
NOTE
If your LED pattern does not appear in Table 11-1 on page 213, your
problem could still stem from corrupted BIOS or firmware. Always flash
the BIOS and firmware before attempting other solutions.
If you still have a problem after flashing the BIOS and firmware and
following the suggested solutions in Table 11-1 on page 213, contact
customer support.
