Connecting to the Network

3.7 CONNECTING TO THE NETWORK
This section provides the procedures for connecting unshielded twisted pair (UTP) segments from
the network or other devices to the 7H4382-49
ports on the 7G4270-12 or the optional NEM, refer to
Note: If the DFE module is being installed in a network using Link Aggregation, there
are rules concerning the network cable and port configurations that must be followed for
Link Aggregation to operate properly. Before connecting the cables, refer to the
Enterasys Matrix DFE-Platinum Series Configuration Guide for the configuration
information. For details on how to obtain manuals, refer to the

Connecting UTP Cables to 7H4382-49 and 7G4202-30

The fixed RJ45 front panel connections of the 7H4382-49 are 10/100 Mbps ports. Those on the
7G4202-30 front panel are 10/100/1000 Mbps ports. In either case, 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 7H4382-49 and 7G4202-30 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

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 .
