Connecting UTP Cables to 4H4282-49 or 4H4202-72

The fixed RJ45 front panel connections of the 4H4282‐49 and 4H4202‐72 are 10/100 Mbps ports. The ports have internal crossovers, and also support automatic‐polarity sensing when configured for automatic‐negotiation.

If automatic‐negotiation is not activated on a port, use a straight‐through cable when connecting a workstation to the port. When connecting a networking device to the port, such as a bridge, repeater, or router, use a crossover cable.

If a port is set for auto‐negotiation, automatic‐polarity sensing is also activated. Automatic‐polarity sensing eliminates the need for a crossover cable, regardless if the connection is to another network device or a workstation.

Note: All RJ45 front panel ports on the 4H4282-49 and 4H4202-72 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.

In this procedure, the 4H4282‐49 is used as the example to connect a twisted pair segment with RJ45 connectors to the DFE‐Gold module. Refer to Figure 3‐4 and proceed 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 module by inserting the RJ45 connector on the twisted pair segment into the appropriate RJ45 port connector.
