Jumper Setting for Rear I/O
Rear I/O interfaces are only available on Rear I/O versions of the board.
In order to implement the system Rear I/O feature, a system slot Rear I/O backplane is
necessary. This backplane must comply with the CompactPCI Specification PICMG 2.0
R3.0, October 1999.
Ethernet Interface
Ethernet signals are available on J2 when the board is ordered for Rear I/O configura-
tion. To configure the Ethernet port for Rear I/O requires the installation of zero ohm
resistors on the board to connect the signals to the J2 connector.
!
Warning:
If the board is ordered for 64-bit CompactPCI the Rear I/O
feature is not supported. The Rear I/O jumpers and resistors
must not be configured for Rear I/O. The setting of the Rear I/O
jumpers and resistors may result in damage to your board or
system.
