Connecting to the Network
This section provides the procedures for connecting unshielded twisted pair (UTP)
segments from the network or other devices to the 2G4072‐52. For connections to Mini‐
GBIC ports, refer to
page 3‐9.
Connecting UTP Cables
The fixed RJ45 front panel connections of the 2G4072‐52 are 10/100/1000 Mbps ports. They
have internal crossovers and support automatic‐polarity sensing which eliminates the
need for a crossover cable, regardless if the connection is to another network device or a
workstation.
In this procedure, the 2G4072‐52 is used as the example to connect a twisted pair segment
to the device, as shown in
Figure 3‐4 .
1. Ensure that the device connected to the other end of the segment is powered ON.
2. Connect the twisted pair segment to the device by inserting the RJ45 connector on the
twisted pair segment into the appropriate RJ45 port connector.
Note: If the Enterasys Matrix N SA 2G4072-52 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 N Standalone Series Configuration Guide for the
configuration information. For details on how to obtain manuals, refer to
“Related
Documents” on page xvi .
Note: All RJ45 front panel ports on the 2G4072-52 support Category 5 Unshielded
Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. You can use
Category 3 cable only for 10 Mbps connections.
