6.
Be sure all cables are connected to the correct locations and are the correct lengths. For more
information, see the server documentation on the HP website (http://www.hp.com/go/hpsc).
7. Be sure other components were not accidentally unseated during the installation of the new hardware
component.
8. Be sure all necessary software updates, such as device drivers, ROM updates, and patches, are
installed and current, and the correct version for the hardware is installed. For example, if you are using
a Smart Array controller, you need the latest Smart Array Controller device driver. Uninstall any
incorrect drivers before installing the correct drivers.
If the "Unsupported processor detected" message is displayed, update the system ROM to support the
installed processor. For more information, see "Unsupported processor stepping with Intel processors
(on page 56)."
9. After installing or replacing boards or other options, run RBSU or the options in BIOS/Platform
Configuration (RBSU) in the UEFI System Utilities to be sure all system components recognize the
changes. If you do not run the utility, you may receive a POST error message indicating a configuration
error.
a. Check the settings in RBSU or in UEFI System Utilities, depending on your server.
b. Save and exit the utility.
c. Restart the server.
For more information on RBSU, see the HP ROM-Based Setup Utility User Guide on the Documentation
CD or the HP RBSU Information Library (http://www.hp.com/go/rbsu/docs).
For more information on UEFI System Utilities, see the HP UEFI System Utilities User Guide in the HP UEFI
Information Library (http://www.hp.com/go/ProLiantUEFI/docs).
10. Be sure all switch settings are set correctly. For more information about required switch settings, see the
labels located on the server access panel or the server documentation on the HP website
(http://www.hp.com/go/hpsc).
11. Be sure all boards are properly installed in the server.
12. To see if the utility recognizes and tests the device, run HP Insight Diagnostics (on page 73).
13. Uninstall the new hardware.
Unknown problem
Action:
1. Check the server LEDs to see if any statuses indicate the source of the problem. For LED information, see
the server documentation.
2. Power down and disconnect power to the server. Remove all power sources to the server.
3. Be sure no loose connections (on page 17) exist.
4. Following the guidelines and cautionary information in the server documentation, reduce the server to
the minimum hardware configuration by removing all cards or devices that are not necessary to power
on the server. Keep the monitor connected to view the server power-on process. Before completing this
step, see "Breaking the server down to the minimum hardware configuration (on page 16)."
5. Reconnect power, and then power on the system.
