Installing the Catalyst 3920 3-5
Surface Mounting the Catalyst 3920
Follow these steps to mount the Catalyst 3920 as a standalone unit:
Step 1
Obtain the chassis feet from the accessory kit.
Step 2
Remove the protective paper from the adhesive surface of the feet and place the four feet
in each of the four embossed, recessed areas located in the corners of the bottom of the
Catalyst 3920.
Step 3
Place the Catalyst 3920 on the surface where it is to be used.
Step 4
Continue with the instructions in the “Cabling the Catalyst 3920” section.
Cabling the Catalyst 3920
This section provides instructions for connecting devices (such as hubs, servers, personal computers,
and workstations) to a Catalyst 3920. Remember the following tips when connecting cables:
•
Avoid excessively stretching or bending the cables. Support the cables to avoid excessive strain.
•
Avoid routing the cables near sources of electromagnetic interference, such as motors and
fluorescent lights.
•
Avoid routing the cables through aisles and other areas where people walk. If routing through
aisles is unavoidable, use floor cable covers or similar material to secure and protect the cables.
Connecting Devices to Token Ring Ports Using Loose Cables
Use this procedure if you will not use in-the-wall cables to connect devices to Token Ring ports on
the Catalyst 3920.
If you will use in-the-wall cables (building wiring), go to the “Connecting Devices to the Token Ring
Ports Using Building Wiring” section.
Step 1
Using the Cabling Chart provided by your network administrator as a guide, connect the
cables between the Catalyst 3920 and the other devices. Depending on the cable type you
use, the device end of the cable may also have a 9-pin D-shell or 150-ohm data connector.
Step 2
Label both ends of each cable so that it will be easy to find the device if you have to
troubleshoot a network problem.
The label should indicate: the room location of the device at the other end, a unique cable
identification number, the MAC address of the connected device, and the number of the
port to which the cable is attached.
Step 3
Continue with the instructions in the “Powering On the Catalyst 3920” section.
Connecting Devices to the Token Ring Ports Using Building Wiring
Use this procedure if you will use in-the-wall cables to connect devices to the Catalyst 3920.
Step 1
Using the Cabling Chart provided by your administrator as a guide, connect the cables
between the devices and the faceplates.
Step 2
Label the faceplate, so that it will be easier to find the device if you have to troubleshoot
a network problem.
Step 3
In the wiring closet, connect a cable to the Token Ring connector on the patch panel or
other equipment where the building wiring terminates.
