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 (SW2) on the system board. Refer to the HP ProLiant DL185 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 described on page 62. 2. If necessary, remove any expansion boards, assemblies, or cables that prevent access to the press CMOS button (SW2). 3. Locate the clear CMOS button (SW2) on the system board. 4. Press clear CMOS button (SW2) to clear the CMOS memory. 5. Perform the post-installation procedures as described on page 63. 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 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 either: • Displays a POST error message • Emits a series of beep codes (requires an optional expansion board) 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: System BIOS configuration 30

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 (SW2) on the system board. Refer to the HP
ProLiant DL185 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 described on page 62.
2.
If necessary, remove any expansion boards, assemblies, or cables that prevent access to the
press CMOS button (SW2).
3.
Locate the clear CMOS button (SW2) on the system board.
4.
Press clear CMOS button (SW2) to clear the CMOS memory.

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)
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:
