System Board Components 15
I

C Connector
This connector is part of the system monitoring. It carries the signals of the
I
2
C bus which include identifying information and status for major system
components.
RAID Cage Connector
The RAID cage connector connects the SCSI backplane to the system
board to allow status and monitoring of backplane and SCSI drive.
System Jumpers
These jumpers allow you to set certain characteristics of the system. Some
jumpers are reserved and are not described in this section. Do not change
any jumper unless it is necessary to configure the system. In some cases,
changing the settings of reserved jumpers can cause damage to the system
board.
Clear CMOS Jumper
This jumper allows you to clear the CMOS memory. You should only do
this if you cannot access the normal methods of modifying the CMOS and
modifications to the CMOS are necessary. Clearing CMOS memory
returns all BIOS Setup settings to the default values.
CPU Speed Setting Jumper
This jumper allows you to set the speed of the processor. Both processors,
in dual processor configurations, must have the same speed rating. If
processors of different speeds are used in the same system, the processors
must run at the speed of the slower processor.
Battery
Provides the power to maintain the CMOS memory when the system is
turned off or unplugged.
