Chapter 3: Installing the Switch

Selecting a Site

Matrix V-Series V2H124-24P 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
