3.3.2 Connecting UTP Cables to the 5H103-48

When facing the front panel of the 5H103-48, the RJ21 connectors from top to bottom represent

Ethernet/Fast Ethernet segments 1 through 12, segments 13 through 24, 25 through 36, and 37

through 48, respectively.

To connect a UTP segment to the 5H103-48, proceed as follows:

1. Ensure that the device connected to the other end of the segment is powered ON.

2. If using an RJ21 straight connector, plug it into the appropriate RJ21 port as shown in

Figure 3-5. If using an RJ21 angle adapter supplied with the switch, inse rt th e angle ada pter a s

shown in Figure3-6. The RJ21 angle adapter allows the cables to be positioned along the front

of the device when using a right angle RJ21 connector. See example in Figure3-7.
