The connection requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use
Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections,
and Category 3 or better for 10BASE-T connections.

Copper Cabling Guidelines
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
10/100BASE-TX Pin Assignments
All 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can use straight-through or
crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3,
and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.

• Do not plug a phone jack connector in the RJ-45 port. This may damage this device.
• Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.
