Using the LEDs and e-buzzer to Troubleshoot Your System

Chapter 2 51

The Troubleshooting section of the zx6000/rx2600 Operation &

Maintenance Guide found at http://www.hp.com/go/bizsupport provides a

table with a list of faults associated with the various possible LED

lighting sequences.

Troubleshooting with the e-buzzer

When your system starts up, the system ﬁrmware performs pre-boot

diagnostics to test your hardware conﬁguration for any problems. If a

problem is detected during pre-boot, the pre-boot diagnostics will emit an

audio signal through the workstation’s internal speaker.

The pre-boot diagnostics emits an audio sequence with two kinds of

sounds. The ﬁrst is an unusual series of tones that indicate an anomaly

has been detected. This series of sounds also contains an electronic

signal that can be sent through a telephone line to an authorized Help

Desk or HP Support, if necessary. This signal cannot be interpreted by

the human ear. However, it can be decoded by Help Desk equipment to

extract the workstation model, serial number and details about any

faults. To send this signal to HP Support, you need to hold your

telephone next to the e-buzzer Icon on the system’s front panel. See
