Connecting to the Network
This section provides the procedures for connecting unshielded twisted pair (UTP) segments from
the network or other devices to the 2G4082‐25 (“
Connecting UTP Cables ” on page 3‐6).
Connecting UTP Cables
The fixed RJ45 front panel connections of the 2G4082‐25 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.

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-Diamond/
Platinum Series Configuration Guide for the configuration information. For details on how to obtain
manuals, refer to the
“ Related Documents ” on page xii .
Note: All RJ45 front panel ports on the 2G4082-25 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.
