Connecting UTP Cables to 4H4283-49 or 4H4203-72
The 4H4283-49 and 4H4203-72 have fixed RJ21 connectors. Each RJ21 connector can
support up to 12 segments. You can use either straight RJ21 cable connectors or right-
angle RJ21 connectors with optional RJ21 angle adapters.
To connect a UTP segment to the 4H4283-49
or 4H4203-72, proceed as follows:
1. Ensure that the device connected to the other end of the segment is powered ON. If
using RJ21 straight connectors, proceed to step 2. If using RJ21 connectors with
optional RJ21 angle adapters, proceed to step 3.
2. If using an RJ21 straight connector, refer to Figure 3-13 and proceed as follows. If
using RJ21 right-angle cable connectors, proceed to Step 3 on page 3-19.
a. Plug the RJ21 straight connector into the appropriate RJ21 port connector.
b. Tighten the two screws to secure the RJ21 straight connector to the RJ21 port
connector.
c. Proceed to step 4.
Note: The cable pinouts for a 25-pair cable (RJ21) can be found in the Cabling Guide.
