Power-On Self-Test (POST) When the server boots up, a series of tests are displayed on the screen. This is referred to as PowerOn 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 will display a POST error message. 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. 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. POST-related troubleshooting Perform the following procedures when POST fails to run, error messages are displayed. If the POST failure is during a routine bootup, verify the following conditions: • All external cables and power cables are firmly plugged in. • The power outlet to which the server is connected is working. • The server and monitor are both turned on. The bicolor power status LED indicator on the front panel must be green. • The monitor's contrast and brightness settings are correct. • All internal cables are properly connected and all boards firmly seated. • The processor is fully seated in its socket on the system board. • The heat sink is properly installed on top of the processor. • All memory modules are properly installed. If the POST failure occurs after installing an accessory, perform the following steps: 1. Perform the pre-installation procedure. 2. If necessary, remove any expansion boards, assemblies, or cables that prevent access to the system components. System BIOS configuration 35

System BIOS configuration 35
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 will display a POST error message.
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.
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.
POST-related troubleshooting
Perform the following procedures when POST fails to run, error messages are displayed.
If the POST failure is during a routine bootup, verify the following conditions:
•
All external cables and power cables are firmly plugged in.
•
The power outlet to which the server is connected is working.
•
The server and monitor are both turned on. The bicolor power status LED indicator on the front
panel must be green.
•
The monitor's contrast and brightness settings are correct.
•
All internal cables are properly connected and all boards firmly seated.
•
The processor is fully seated in its socket on the system board.
•
The heat sink is properly installed on top of the processor.
•
All memory modules are properly installed.
If the POST failure occurs after installing an accessory, perform the following steps:
1.
Perform the pre-installation procedure.
2.
If necessary, remove any expansion boards, assemblies, or cables that prevent access to the
system components.
