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 3-1 on page 53 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 • q = Off Unless the LED pattern indicates that the BIOS is in recovery mode (YRqq), or that BIOS recovery is complete (GRqq), 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 3-1 on page 53. If your LED pattern does not appear in Table 3-1 on page 53, 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 3-1 on page 53, refer to the HP x4000 Workstation Technical Reference at www.hp.com/workstations/support or contact customer support. 52 Chapter 3
