MatrixBus™ connection

Jumpers
Ports 17 and 18 must be configured through jumpers to determine the duplex mode, the rate and autonegotiation. The settings depend upon whether the ports are used as 10Mbps or 100Mbps conncetions.
Jumpers 1 -3 control Port 18, which is an external connection. Jumpers 4-6 control Port 17, which is a
backplane connection.
The default configuration at Power Up is: J1 is closed, all the other jumpers are open. In order to
make changes, remove the XM542 card from the GigaHUB chassis, reconfigure and then reinstall.
