• The site should:
- be at the center of all the devices you want to link and near a power
outlet.
- be out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference. The temperature should
be within 0 to 50 °C (32 to 122 °F) and its humidity within 5% to 95%,
non-condensing.
- be located in a cool dry place, and have adequate space (approximately
ten centimeters or four 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 (± 10%), 50 to 60 Hz (± 3Hz), 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.
Installing Ethernet Cabling
To ensure proper operation when installing 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 should be 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.
