Connecting to the Network

3.5.1Connecting 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.

3.Tighten the two screws on the RJ21 straight cable connector to secure it to the device.

NOTE

The cable pinouts for a 25-pair cable (RJ21) can be found in the Cabletron Systems Cabling Guide. Refer to Section 1.7 for details on how to obtain this document.
