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
