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 or 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 will be 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, or
•
Emits a series of beep codes
