Problems with new hardware
1.
Be sure the hardware being installed is compatible with the server.
2.
Be sure the new hardware is installed properly. Tobe sure that all requirements are met, see the
device, server, and OS documentation.
Common problems include:
o
Connection of the data cable, but not the power cable, of a new device
o
Loose connections exist
3.
Be sure no memory, I/ O or interrupt conflicts exist.
4.
Be sure all cables are connected to the correct locations.
5.
Be sure other components were not accidentally unseated during the installation of the new
hardware component.
6.
Be sure all necessary software updates, such as device drivers, ROM updates, and patches,
are installed and current, and is the latest version.
7.
Be sure all boards are properly installed in the server.
8.
Boot to the BIOS to determine if the utility is configured.
9.
Replace another different known functional device to plug into the location tobe sure that the server is
not faulty.
10.
Replace another same model device.
Unknown problem
1
.
Check the server LEDs to see if any statuses indicate the source of the problem.
2
.
Power down and disconnect power to the server. Remove all power sources to the server.
3
.
Be sure no loose connections exist.
4
.
Add the debug card before reconnecting power.
5
.
Reconnect power, and then power on the system.
6
.
See the number shown on the debug card. If there is an error on the debug card indicating that the
server will stop, see the BIOS specifications(standard status codes) to determine where the process
stopped. For example, if the number on the debug card points to memory, re-seat the memory. If
reseating the memory does not resolve problem, consider using a different memory module to verify
it is a memory problem.
