Ethernet Cabling
To ensure proper operation when installing the switch 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
