The fixed front panel ports of the 6H302-48 are 10/100 RJ45 ports with internal crossovers. When
connecting a workstation to these ports, use a straight-through cable. When connecting networking
devices to these ports, such as a bridge, repeater, or router, use a crossover cable.

Connect a twisted pair segment to the 6H302-48 as follows:

1. Ensure that the device connected to the other end of the segment is powered ON.

2. Connect the twisted pair segment to the 6H302-48 by inserting the RJ45 connector on the

twisted pair segment into the desired RJ45 port as shown in

Figure 3-3

NOTE: If the module is being installed in a network using SmartTrunking, there are
rules concerning the network cable and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the cables, refer to the
appropriate Local Management User’s Guide for the configuration information.

NOTE: All RJ45 front panel ports on the 6H302-48 support Category 5 Unshielded
Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. Category 3
cable may be used if the connection is going to be used only for 10 Mbps.
