6. Connect the Network Cables
Connect the network cables, described under “Cabling Infrastructure” (page
2-4), from the network devices or your patch panels to the fixed RJ-45 ports
on the switch or the ports on any transceivers you have installed in the switch.
Using the RJ-45 Connectors (10/100Base-TX ports)
To connect:
Push the RJ-45 plug into the RJ-45
jack until the tab on the plug clicks
into place. When power is on for the
switch and for the connected device,
the Link LED for the port should light
to confirm a powered-on device (for
example, an end node) is at the other
end of the cable.
If the Link LED does
not
go on when
the network cable is connected to the
port, see “Diagnosing With the LEDs”
in chapter 3, “Troubleshooting”.
To disconnect:
Press the small tab on the plug and
pull the plug out of the jack
.
Connecting Cables to the Transceivers
If you have any transceivers installed in the switch, the type of network
connections you will need to use depends on the type of transceivers you have
installed. See the documentation accompanying the transceivers for cabling
configurations and procedures for those transceivers.
The transceiver documentation will also cover troubleshooting procedures
for connections to the transceivers, but, in general for all the switch ports,
when a network cable from an active network device is connected to the port,
the Link LED for that port should go on. If the Link LED does
not
go on when
the network cable is connected to the port, see “Diagnosing With the LEDs”
in chapter 3, “Troubleshooting”.
