Copper Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration,
which enables you to use standard straight-through twisted-pair cables to connect
to any other network device (PCs, servers, switches, routers, or hubs).
The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable with RJ-45 connectors at both ends.
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 5, 5e or better cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections..
◆
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
