Troubleshooting Your System

Using the LEDs and e-buzzer to Troubleshoot Your System

Chapter 250

LAN LED

The LAN LED provides an indication as to whether the system is

communicating over the LAN. If the LED is not green, the system is off,

and therefore, the system is not communicating over the LAN. If the

LAN LED is solid green, there is no system LAN communication taking

place, but the system is ready to communicate over the LAN. If the LAN

LED is blinking green, the system is communicating over the LAN.

Locator LED and Button (Rack-mounted Systems only)

The locator LED provides a means for locating the system on which you

intend to work. For example, you ﬁnd out that system number 5 in your

rack of systems has a LAN cable that needs to be replaced. This will

require that you walk all the way around to the back of your rack of

systems to replace the cable. Once you get behind the rack of systems,

you need to locate the system that needs the cable replaced. The locator

LED makes this easier. When the locator button is pressed in, the locator

LED begins to ﬂash blue at a frequency of one blink per second both on

the front of the system and the back, thus making it easy to locate the

system on which you need to work.

The locator LED can also be activated or deactivated by use of the locator

button on the back panel of the system or by use of a Management

Processor (MP) command.

Diagnostic LEDs

There are four diagnostic LEDs located on the front bezel of your system.

They are labeled one through four

NOTE The zx6000 HP Workstation boot progress is indicated by LEDs 1-4.

During the boot-up the LEDs will turn on in sequence until the EFI

prompt is reached. These LEDs will be off if there is a Management

processor in the workstation.

WARNING The rx2600 HP Server boot process will be monitored by the

Management Processor Card and not by the LEDs. Refer to the

Management Card section for more details.
