Power-On Self-Test diagnostics
The Power-On Self-Test (POST) is a system diagnostic program (stored in the Basic Input/
Output System (BIOS)) that runs each time the 600r server starts up. The function of the POST
is to test system components and then display status messages.
To run the POST
1. Power up the CallPilot server and monitor.
Result: After a few seconds, POST begins to run.
After the memory test, various screen prompts and messages appear.
2. Observe the screen for any error messages and listen for POST beep codes.
If the server halts before POST ends, the server emits a beep code indicating that
a fatal system error requires immediate attention. For more details, see Interpreting
POST diagnostics on page 23.
If POST can display a message on the monitor, the server emits two beeps as the
message appears.
Record the message that appears on the monitor and the beep code that you hear.
This information is useful if you need assistance from your technical support
representative.
Interpreting POST diagnostics
This section provides an explanation of the POST diagnostic codes.
POST beep codes
If an error occurs before video initialization, POST emits beep codes that indicate errors in
hardware, software, or firmware.
Beep codes are represented by a series of separate tones, each equal in length. Beep codes
are alarms that are physically heard during the initial system boot. For example, a series of
three beeps and no video indicates memory failure. If the system generates beep codes during
bootup, contact Avaya Support for further instructions.
