3.5.1 Connecting Cables to CONN 1 Through 4
The device uses RJ21 connectors for the cables connected to CONN 1
through CONN 4 (2H23-50R) or CONN 1 through CONN 3 (2H33-37R).
Each of the 12 repeater ports associated with each RJ21 connector have
internal crossovers.
To connect an RJ21, 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 3-6 .

it to the device.
NOTE
The cable pinouts for a 25-pair cable (RJ21) can be found in
