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: 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.

•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
