Selecting a Site for the Switch
Be sure to observe the following requirements when choosing a site for your
switch:
G Make sure that the switch’s power is accessible and cables can be
easily connected.
G Air flow around the switch and through its vents on the side and rear
must not be restricted.
G If you are installing the switch on a desk, make sure it is placed on a
level, secure desktop.
G Do not place objects on top of the switch.
G Do not expose the switch to moisture or water.
G Make sure it is in a dust-free environment.
G Use dedicated power circuits or power conditioners to supply reliable
electrical power to the network devices.
Installing the Twisted Pair and Fiber Optic Cabling
When installing the twisted pair cable for your network, be sure to observe the
following guidelines:
G For 10Base-T operation (10 Mbps), use Category 3 100-ohm or better
shielded or unshielded twisted pair cabling.
G For 100Base-TX operation (100 Mbps), use Category 5 100-ohm or
better shielded or unshielded twisted pair cabling.
G The maximum length for a twisted pair cable is 100 meters (328 feet).
G Since the twisted pair ports automatically configure themselves as
either MDI or MDI-X, you can use either straight-through or crossover
twisted pair cabling, regardless of the type of end node that you are
connecting to each port.
G Cabling should be kept away from sources of electrical noise such as
radios, transmitters, broadband amplifiers, power lines, electric
motors, and fluorescent fixtures.
When installing the fiber optic cabling for your network, be sure to observe the
following guidelines:
G The fiber optic port on the switch requires either 54/125 or 60/125
micron core/cladding multimode fiber optic cable.
G The maximum operating distance of the fiber optic port on the switch
is 2 kilometers (1.25 miles).
