Installing the Switch
Selecting a Site
Switch units 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 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 that 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 2.44 m (8 feet) of each device
 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 switch into a network, make sure that the current cables
are suitable for 10BASE-T or 100BASE-TX 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 and Category 5 or better for 100BASE-TX.
 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
