Interpreting POST diagnostics
The Power-On-Self-Test (POST) is a system diagnostic program (stored
in the BIOS) that runs each time the 703t server is started. The function
of POST is to test system components and then to display status
messages.
POST reports on the system status using POST beep codes. If an error
occurs before video initialization, POST emits beep codes that indicate
errors in hardware, software, or firmware.
A beep code is a series of separate tones, each equal in length. Record
the beep codes that you hear before calling your Nortel customer support
representative.
Types of beep codes
There are three types of beep codes on the 703t server:
„
BIOS recovery beep codes (during a BIOS recovery procedure)
„
bootblock error beep codes (for normal operation)
„
bootblock error 3-beep codes (for normal operation)

ATTENTION
Some POST beep codes are critical and require you to
replace your motherboard. Refer to the tables in this
section for more information about beep codes.
