Jumpers and connectors

This topic provides specific information about the jumpers. It also provides some basic information about jumpers and switches
and describes the connectors on the various boards in the system. Jumpers on the system board help to disable the system and
setup passwords. You must know the connectors on the system board to install components and cables correctly.

Topics:

•

System board jumper settings

•
