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
