Chapter 4: Installing the Switch

4. Installing the Switch

4.1 Selecting a Site

NOTE: The switch can be mounted in a standard 19-inch equipment rack (via the included rackmount kit). Follow the guidelines below when choosing a location.

The site should:

•Be located at the center of all the devices you want to link and near a power outlet.

•Be able to maintain its temperature within 32 to 140° F (0 to 60° C) and its humidity within 10% to 90%, non-condensing.

•Be accessible for installing cabling and maintaining the devices.

•Allow the status LEDs to be clearly visible.

NOTES:

Make sure the twisted-pair Ethernet cable is always routed away from power lines, radios, transmitters, or any other electrical interference.

Make sure that the switch is connected to a separate grounded power outlet.

4.2 Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable for 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) cable with RJ-45 connectors. We recommend Category 5 or Category 5e with a maximum length of 328 feet (100 meters) for 100BASE-TX, and Category 5e or 6 with a maximum length of 328 feet (100 meters) for 1000BASE-T.

•Protection from radio frequency interference emissions.

•Electrical surge suppression.

•Separation of electrical wires and data based network wiring.

•Safe connections with no damaged cables, connectors, or shields.
