Connecting to the Network
3.4CONNECTING TO THE NETWORK
This section provides the procedures for connecting unshielded twisted pair (UTP) and fiber optic segments from the network or other devices to the 2H252-25R.
NOTE: If the 2H252-25R is being installed in a network using SmartTrunking, there are rules concerning the network cable and port configurations that must be followed for SmartTrunking to operate properly. Before connecting the cables, refer to the Enterasys Networks SmartTrunk User’s Guide for the configuration information.
3.4.1Connecting Twisted Pair Cables to Fixed Ports
NOTE: If a port is connected to a 10-Mbps segment, Category 3 Unshielded Twisted Pair (UTP) cable is sufficient to use. However, if the segment is to carry 10- or
100-Mbps transmissions, use only Category 5 UTP cabling that has an impedance between 85 and 111 ohms.
Ports 1 through 24 on the 2H252-25R are 10/100 ports with internal crossovers. When connecting a workstation, use a straight-through cable. When connecting networking devices, such as another bridge, repeater, or router, use a crossover cable.
To connect a twisted pair segment to the 2H252-25R, proceed as follows:
1.Ensure that the device connected to the other end of the segment is powered ON.
2.Connect the twisted pair segment to the 2H252-25R by inserting the RJ45 connector on the twisted pair segment into the appropriate RJ45 port on the device. Figure 3-6shows a twisted pair segment being plugged into port 7.
