Power-On Self-Test
Power-On Self-Test (POST) is a series of diagnostic tests that runs automatically on
ProLiant and TaskSmart servers when the system is powered up. POST checks
firmware and assemblies to ensure that the system is functioning properly.
If POST finds an error in the system, an audible beep (if supported by your system),
visual message, or both indicate an error condition. If an error code is displayed on
the screen during POST or after the system is reset, use the instructions in
Appendix C, which provides a complete list of POST error messages generated by
ProLiant and TaskSmart servers. Your system generates only the codes that are
applicable to your configuration and options.
NOTE:
Many of the actions listed require you to run Diagnostics or the server setup utility
provided with your server. Steps for running Diagnostics are provided in the “Diagnostics”
section in this chapter.
BIOS Serial Console
The BIOS Serial Console, available for some servers, provides you with the
capability to view the POST error messages, configure option ROMs, and use RBSU
through a serial connection without needing a local keyboard and monitor. If your
server supports the BIOS Serial Console, refer to the
BIOS Serial Console User
Guide
for more information.
Server Blade Health Driver
Available on some ProLiant BL servers, the server blade health driver monitors
operational data of the server blades and logs abnormal conditions. The log created
by the health driver can be accessed with Insight Manager 7.
