Power-On Self Test (POST)
When the server boots up, a series of tests are displayed on the screen. This is referred to as Power-
On Self-Test (POST). POST is a series of diagnostic tests that checks firmware and assemblies to
ensure that the server is properly functioning. This diagnostic function automatically runs each time the
server is powered on.
These diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the
board or component that needs to be replaced, as indicated by the error messages. Most server
hardware failures are accurately isolated during POST. The number of tests displayed depends on the
configuration of the server.
POST error indicators
When POST detects a system failure, it either:
• Displays a POST error message
• Emits a series of beep codes (requires an optional expansion board)
Recoverable POST Errors
Whenever a non-fatal error occurs during POST, an error message describing the problem appears
onscreen. These text messages are displayed in normal video (white text on black background). It
shows the details of the error. The following is an example of a POST error message:
Error message 1 of 1: Error code 0103
Keyboard not detected - Keyboard error
In some cases an error message may include recommendations for troubleshooting or require that you
press the Enter key to display recommendations. Follow the instructions on the screen.
Table 20 lists the most common POST error messages with their corresponding troubleshooting
recommendation.
It is recommended that you correct the error before proceeding, even if the server appears to boot
successfully. If your system displays one of the messages marked below with an asterisk (*), write
down the code and message and contact your HP Customer Support provider.
