Chapter 3: Installing the Switch

Selecting a Site

Switches can be mounted in a standard 19-inch equipment rack or on a flat surface.

Be sure to follow the guidelines below when choosing a location.

• The site should:

- be at the center of all the devices you want to link and near a power outlet.

- be able to maintain its temperature within 0 to 50 °C (32 to 122 °F) and its

humidity within 5% to 95%, non-condensing

- provide adequate space (approximately five centimeters or two inches) on all

sides for proper air flow

- be accessible for installing, cabling and maintaining the devices

- allow the status LEDs to be clearly visible

• Make sure twisted-pair cable is always routed away from power lines, fluorescent

lighting fixtures and other sources of electrical interference, such as radios and

transmitters.

• Make sure that the unit is connected to a separate grounded power outlet that

provides 100 to 240 VAC, 50 to 60 Hz, is within 2 m (6.6 feet) of each device and

is powered from an independent circuit breaker. As with any equipment, using a

filter or surge suppressor is recommended.

Ethernet Cabling

To ensure proper operation when installing the switches into a network, make sure

that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T

operation. Check the following criteria against the current installation of your

network:

• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables

with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better

for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.

• Protection from radio frequency interference emissions

• Electrical surge suppression

• Separation of electrical wires (switch related or other) and electromagnetic fields

from data based network wiring

• Safe connections with no damaged cables, connectors or shields
