Connecting to the Network

To connect twisted pair segments to the switch, refer to Figure 3‐12 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).

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:

a.Verify that the cabling being used is Category 5 or better with an impedance between 85 and 111 ohms with a maximum length of 100 meters (328 feet).

b.Verify that the device at the other end of the twisted pair segment is on and properly connected to the segment.

c.Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts and check the cable for continuity. Typically, a crossover cable is used between hub devices but this is not necessary. A straight‐through cable can be used to connect between the switch and any device. Refer to Figure 3‐13 and Figure 3‐14 for four‐wire RJ45 connections. Refer to Figure 3‐15 and Figure 3‐16 for eight‐wire RJ45 connections.
