This chapter provides a preferred methodology (strategies and procedures) and tools for
troubleshooting server error and fault conditions.
This chapter addresses the following topics:
■
"Identifying and Diagnosing Hardware Problems" (page 109)

"SEL and FPL Log Entries" (page 131)

Identifying and Diagnosing Hardware Problems

Should a hardware failure occur, the system LEDs and e-buzzer help you identify the problem:
■
Server beeps and e-buzzer. The rx2600/zx6000 has an e-buzzer that beeps in specific patterns
to identify errors when the server boots. The e-buzzer can also send encoded data over the
phone to help support representatives identify more complex problems.
■
LEDs. The lights on the front bezel of the server change color and blink in different patterns
to help identify specific hardware problems. LEDs on the rear panel of the server display
LAN status.
■
The System Event Log (SEL) provides detailed information about the errors identified by the
e-buzzer and LEDs.
If the LEDs and e-buzzer do not give you enough information to identify the problem you are
experiencing, HP also provides diagnostic tools with each operating system.

The System e-buzzer

If a problem is detected at any time when the server is booting or running, the e-buzzer emits
audible beeps and an encoded error message.
■
The audible beeps consist of a modem-like sound repeated three times, followed by
zero-seven beeps of a single frequency at one-second durations, each separated by one
second. The e-buzzer emits a different number of beeps for each type of error. More detailed
information is provided by the LEDs.
■
The electronic signal can be sent through a telephone line to an authorized help desk or HP
Support. This signal can be decoded by help desk equipment to extract the server model,
serial number and details about any faults. To send this signal to HP Support, hold your
telephone next to the LED 1 on the server front bezel when the server is booting.
■
The e-buzzer does not report all problems, only the problems listed below. If the e-buzzer
indicates an error, check the SEL.
