Connecting to the Network
This section provides the procedures for connecting unshielded twisted pair (UTP) segments from the network or other devices to the 2S4082‐25 (“Connecting UTP Cables to the 2S4082‐25” on page 4‐7) and connecting fiber optic cables to the Mini‐GBICs of the 7S4280‐19 and 2S4082‐25 (“Connecting Fiber‐Optic Cables to Mini‐GBICs” on page 4‐11).
Note: If the NAC Controller PEP 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
Connecting UTP Cables to the 2S4082-25
The fixed RJ45 front panel connections of the 2S4082‐25 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.
