2.2 Installing the Switch
The switch is designed for office use, where it can be free standing, desktop-mounted, or
mounted in most standard 19-inch equipment racks. If you prefer, you can rack-mount the
switch in a wiring closet or equipment room using two mounting brackets and six screws.
When choosing a location for the switch, observe the following guidelines:
z
Make sure the switch is accessible and that the cables can be connected easily.
z
Keep cabling away from sources of electrical noise such as radios, transmitters, and
broadband amplifiers as well as power lines and fluorescent lighting fixtures.
z
Prevent water or moisture from entering the switch case.
z
Make sure there are no obstructions to restrict airflow around the switch. We
recommend that you provide a minimum of 50 millimeter (2-inch) clearance.
z
Do not place liquids or other objects on top of the switch.
z
If the switches are freestanding, do not stack more than four switches on top of one
another.
2.2.1 Pre-Installation Considerations
Fast Ethernet Topology Considerations
If you will be using the switch for Fast Ethernet (100 Mbps) operation, observe the
following guidelines:
z
The maximum unshielded twisted-pair (UTP) cable length is 100 meters (328 feet) over
Category 5 cable.
z
Single-repeater topologies permit a total network span of 325 meters (1066 feet).
Full-Duplex Considerations
The switch provides full-duplex support for its Fast Ethernet ports. Full-duplex operation
allows frames to be sent and received simultaneously, doubling a link’s potential data
throughput. If you will be using the switch in full-duplex mode, the maximum UTP cable
length is 100 meters (328 feet) over Category 5 cable.
2.2.2 Desktop or Shelf Mounting
To install the switch on a desktop or shelf, simply complete the following steps:
Step 1
Place the switch on a desktop or shelf near an AC power source.
Step 2
Keep enough ventilation space between the switch and the surrounding objects.
Step 3
Connect the switch to network devices.
A.
Connect one end of a standard network cable to the 10/100 RJ-45 ports
on the front of the switch.
B.
Connect the other end of the cable to the network devices such as printer
servers, workstations or routers.
Note:
It is strongly recommended to use the UTP Category 5 network cabling with RJ-45
tips for the network connection.
