How to Connect to Twisted-Pair Copper Ports
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.
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 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
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.
