1. Reboot the server in a normal manner.
2. During POST, press F10 to access the Setup Utility.
3. Press F9 to load the default values.
4. Press F10 to save the changes and close the Setup Utility.
Clearing 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. Clearing the
CMOS data removes the administrator password.
The clear CMOS setting is on clear CMOS button (SW5) on the system board. Refer to the HP ProLiant
DL180 Generation 5 Server Maintenance and Service Guide for the location of this jumper block and the
clear CMOS setting.
To clear CMOS:
1. Perform the pre-installation procedures.
2. If necessary, remove any expansion boards, assemblies, or cables that prevent access to the press
CMOS button (SW5).
3. Locate the clear CMOS button (SW5) on the system board.
4. Press clear CMOS button (SW5) to clear the CMOS memory.
5. Perform the post-installation procedures.
6. During POST, press F10 to access the Setup Utility.
7. Press F9 to load the system default values.
8. Press F10 to save the changes you made and close the Setup Utility.
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)
