Connecting Network Devices
The SMC8748L2 switch is designed to interconnect multiple segments
(or collision domains). It can be connected to network cards in PCs and
servers, as well as to hubs, switches or routers. It may also be connected to
remote devices using the optional SFP tranceivers or optional 10GBASE
module with XFP transceivers.
Twisted-Pair Devices
Each device 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.
Cabling Guidelines
The RJ-45 ports on the switch support 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).
See Appendix B for further information on cabling.

Caution: Do not plug a phone jack connector into an RJ-45
port. This will damage the switch. Use only twisted-pair cables
with RJ-45 connectors that conform to FCC standards.
