Connecting To The Network; Connecting Utp Cables To 7G4202-60 Or 7G4282-41 - Enterasys Matrix 7G4282-41 Hardware Installation Manual

CONNECTING TO THE NETWORK

This section provides the procedures for connecting unshielded twisted pair (UTP)
segments from the network or other devices to the 7G4282‐41 ("Connecting UTP Cables to
7G4202‐60 or 7G4282‐41" on page 3‐11).
Connecting UTP Cables to 7G4202-60
The fixed RJ45 front panel connections of the 7G4202‐60 and 7G4282‐41 are 10/100/
1000 Mbps ports. These 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.
In this procedure, the 7G4202‐60 is used as the example to connect a twisted pair segment
to the module. It is also assumed that the chassis power is turned on to provide power to
the module. Refer to Figure
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
the twisted pair segment into the appropriate RJ45 port connector
Note: If the DFE-Platinum module is being installed in a network using Link Aggregation,
there are rules concerning network cables 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

Note: All RJ45 front panel ports on the 7G4202-60
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.
