System Identification (ID) Configuration Utility

Each system main logic board contains a unique ID called the System ID, which
allows application software to determine what server the electronics reside in. This
System ID is stored also on processors and memory expansion boards in the server.
When the SCU is launched, if there is a mismatch between the System ID on the
main logic board and that stored on the processor and/or memory expansion boards,
then the SCU will flag that a mismatch occurred and ask you to enter the correct
server part number from the label on the rear of the server.
The System ID on the main logic board, in certain situations, may change. Known
cases where this occurs include:
•
If the main logic board is replaced in the field because it is defective, the new
main logic board will need to be assigned a System ID that reflects the system in
which the board is installed.
•
When a server has a processor upgrade installed, which results in a new server
part number, then the System ID will also need to be reprogrammed to reflect
the new server part number.
The System ID Configuration Utility (SIDUTIL.EXE) allows you to modify the System
ID field. This utility is located on the BIOS diskette that you created from the Quick
Launch CD ROM.
