Setting Jumper Switches
Setting jumper switches is easiest with the SBP-205 removed from the system. While
the jumper switches are accessible with the SBP-205 installed, it might be necessary
to remove one or more adapter cards if they restrict access to the jumpers.
To access the jumper switches:
1.
Power down the system and remove the power cord and any other
external connectors.
2.
Open the system case.
Follow the instructions in the MaxPro or ProRack User Guide that
accompanied your system.
3.
Locate the jumper switches you wish to set.
4.
Temporarily remove any adapters or connectors that restrict your
access to the jumper switches.
5.
If necessary, temporarily remove the SBP-205 from the system.
For SBP-205 removal and installation procedures, see

To temporarily clear the CMOS:
CMOS contains the system BIOS configurations. Temporarily placing a jumper cap
on JP17 pins 2-3 clears the contents of the CMOS chip.
