Connecting to the Network
The following procedures cover the cable connections from the network or other devices to the switch RJ45 ports or any installed optional Mini‐GBIC.

Connecting UTP Cables
The fixed RJ45 front panel ports are 10/100/1000 Mbps ports and have internal crossovers. When connecting a workstation to these ports, use a straight‐through cable. When connecting networking devices to these ports, such as a bridge, repeater, or router, use a crossover cable.
Note: All fixed RJ45 front panel ports 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.
To connect twisted pair segments to the switch, refer to Figure 3‐13 and proceed as follows:
1.Ensure that the device to be connected at the other end of the segment is powered ON.
2.Connect the twisted pair segment to the switch by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port (for example, Port 8).
