3.7.2 Connecting UTP Cables to the 7H4383-49 or 7H4203-72
The 7H4383-49 and 7H4203-72 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 7H4383-49
or 7H4203-72, 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
➀, refer to Figure 3-12 and proceed as follows.
a. Plug the RJ21 straight connector
➀ into the appropriate RJ21 port connector ➁.
b. Tighten the two screws
➂ to secure the RJ21 straight connector ➀ to the RJ21 port
connector
➁.
c. Proceed to step 4.
Note: The cable pinouts for a 25-pair cable (RJ21) can be found in the Cabling Guide.
