NOTE Troubleshooting Understanding the Diag LEDs 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 no problems are detected during start up, all four LEDs turn off. • If a problem is detected, one or more of the LEDs changes color. If an error is detected (one or more of the LEDs changes color), see Table 2-1 on page 36 for brief list of combinations that you may see when you initially set up your system. For a complete list and more detailed instructions, refer to the x4000 Technical Reference Guide at www.hp.com/workstations/support. The LED patterns are defined by: • R = Red • Y = Yellow • G = Green • G = Off Unless the LED pattern indicates that the BIOS is in recovery mode (YRGG), or that BIOS recovery is complete (GRGG), 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 2-1 on page 36. If your LED pattern does not appear in Table 2-1 on page 36, 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 2-1 on page 36, refer to the HP x4000 Workstation Technical Reference at www.hp.com/workstations/support or contact customer support.

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 no problems are detected during start up, all four LEDs turn off.
•
If a problem is detected, one or more of the LEDs changes color.
If an error is detected (one or more of the LEDs changes color), see Table
2-1 on page 36 for brief list of combinations that you may see when you
initially set up your system. For a complete list and more detailed
instructions, refer to the
x4000 Technical Reference Guide
at
www.hp.com/workstations/support
.
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 2-1 on page 36.
NOTE
If your LED pattern does not appear in Table 2-1 on page 36, 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 2-1 on page 36, refer to the
HP x4000 Workstation Technical Reference
