How to Connect to Twisted-Pair Copper Ports
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.
Table 5: Maximum Twisted-Pair Copper Cable Lengths
Cable Type
1000BASE-T
Category 5, 5e, or 6 100-ohm UTP or STP
100BASE-TX
Category 5 or better 100-ohm UTP or STP
10BASE-T
Category 3 or better 100-ohm UTP
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.
Note:
If the switch receives its DC input power using PoE then IEEE 802.3at-2009
PoE specifications require Category 5 or better cabling.
