Connecting and Terminating
To remove the DB15 connector from the port once it is locked in, examine the
connector for a sliding latch or other locking method. If one is present, slide it to
the unlocked position. Grasp the connector firmly between your thumb and
forefinger. Pull the connector straight out of the port. The spring clips at the side
of the connector should disengage under light strain and allow the connector to
pull free. Do not rock the connector or attempt to jerk it out of the port by the
cable.
RJ45
The RJ45 connector is used to make connections to UTP and some STP cabling.
The instructions which follow detail the process used to connect an RJ45
connector to a station port.
1. Align the RJ45 connector with the socket of the RJ45 port. The connector will
only insert and lock if the raised locking clip of the RJ45 connector is inserted
into the correct location.
Figure 14-2. RJ45 Connector Insertion
2. Press the RJ45 connector into the port until the click of the locking clip is felt.
The pressure required to perform this should be minimal. If you encounter
resistance or excessive friction, remove the connector and check the port for
obstruction. Also, verify that the connector and the port are of the same type.
Once the locking clip snaps into place, the RJ45 connector will remain in the port.
If a link indicator is present for the port, check that it is on. If the indicator is not
on, the port does not have a valid link. Perform each of the following actions until
you reach a resolution of the problem and achieve a link.
• Check that the 10BASE-T device at the other end of the twisted pair segment
is on.
• Verify that the RJ45 connectors on the twisted pair segment have the proper
pinouts.
• Verify the proper crossover of the cable link between the two devices.
• Check the cable for continuity.
