Getting Started
This section describes how to boot the MPC8313E RDB. The on-board flash memory is preloaded with a
flash image from the factory. Before powering up the board, verify that all the on-board DIP switches and
jumpers are set to the factory defaults according to the settings listed in
Section 6.1, “Board Jumper
Settings,”
and make all external connections as described in
Section 6.2, “External Cable Connections.”
CAUTION
Avoid touching areas of integrated circuitry and connectors; static discharge
can damage circuits.
WARNING
Only the 3.3-V PCI Card is supported. Turn OFF power during insertion and
removal of a PCI card.
