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 SFP or XFP.

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.
To connect twisted pair segments to the switch, refer to Figure
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).

3. Verify that a link exists by checking that the Link/Activity LED is ON (solid green or blinking
green). If the Link/Activity LED is OFF, perform the following steps until it is on:

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.
