2.3.18 IDE Setting Jumper on the RTM

A CompactFlash (CF) socket is available on the RTM as a Secondary IDE

port. A 3-pin jumper (CN12) is used to set the CF card as either master or

slave device of the IDE channel.

2.3.19 GbE Connection Selection

The cPCI-6820 supports dual Ethernet connection for PICMG2.16 compliant

backplanes and the RTM. While using the PICMG 2.16 compliant backplane,

it is recommended that none of the GbE ports on the rear panel be used.

There are four mini switches that control the GbE routing located on the

bottom side (solder side) of the RTM. Refer to the following information to

choose either PICMG 2.16 or rear panel Ethernet connections.
