5-4 How to Connect to Twisted-Pair Copper Ports
The RJ-45 management port on the switch supports automatic MDI/MDI-X pinout
configuration, so you can 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, 1000BASE-T, or 10GBASE-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 5e, 6, 6a, or 7 cable for 10GBASE-T connections,
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
