Clear CMOS

You may need to clear the Setup configuration values (CMOS) if the configuration has been
corrupted, or if incorrect settings made in the Setup Utility have caused error messages to be
unreadable.
To clear CMOS:
1. Perform the Pre-Installation Procedure.
2. If necessary, remove any accessory boards or cables that prevent access to the system
configuration switch.
3. Locate the system configuration button (J27-A) on the system board.
4. Press the button. AC power must not be connected.
5. Perform the Post-installation instructions.
6. During POST, press F10 to access the Setup Utility.
7. Load setup defaults by pressing F9.
8. Set time, date, and other system values.
9. Press F10 to close the Setup Utility.
NOTE: Clearing CMOS restore all system configurations and password default settings.

Power-on Self-Test (POST)

Before you can use a server, all devices must be tested and initialized, and the operating system must
be bootstrapped to the memory. This is referred to as Power–on Self-Test or POST. POST is a series of
diagnostic tests that checks firmware and hardware components on the system 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 you need to replace, 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.
During POST you can:
•
Press ESC to skip the HP logo and go to POST boot progress display system summary screen.
•
Press F7 to display the Boot menu.
•
Press F10 to access the Setup Utility.
•
Press F12 to request a network boot (PXE).
