Installing a Switch

Before the Installation

Before installing a switch, users must acertain that a proper operating environ- ment is provided for the network. A right operating environment for a network fea- tures these factors:

-Power : The switch must be provided with a power voltage ranging from 90 to 264 VAC (with an error margin of 10%) at 50 to 60Hz (+/- 3Hz). The switch's power supply will automatically adjust itself to the power available.

-Humidity : The switch and the entire network should be located in the driest area possible. Humid places should be avoided, as humidity can damage the equipment. The non-condensed degree of humidity in which the switch oper- ates ranges from 10 to 90 percent.

-Temperature : While the switch is stored in places with temperatures ranging from -25˚C to 70˚C (-13˚F to 158˚F), it should be operated only in areas with temperatures ranging from 0˚C to 40˚C (32˚F to 158˚F). Be sure that the switch is not located near a heat source.

Physical installation

The physical location of the switch must be carefully planned. Users should be aware of the following factors:

-Ventilation : When installing the switch, make sure there are open spaces of at least 10 centimeters in length, both in front and behind the switch to provide proper ventilation.

-Light : Like any other electronic devices, keep the switch away from direct sun- light or strong light sources.

-Interference : A Fast Ethernet switch should be kept away from any heat source or electromagnetic interference to avoid malfunctions.

-Power source : The switch should be installed near a power outlet, preferably one located in a position that centersl to all network end nodes.

-Hardware : The availability of all connectors and cables required to install the switch and network should be checked.

-Distance from wall adapter : Direct connection between the wall adapters and the switch are preferable.

-Airflow : Nothing should be pressed against the switch's left or right sides. Also, the square ventilation holes located on the switch's sides must not be blocked in any way. Constant cool air is needed to ensure top performance.

Network diameter of an uplinked Fast Ethernet network must not exceed 200

meters. For this reason, the path of cables and the switch's location have to be con- sidered carefully.
