Specifications
Twisted-pair Cable
Caution: DO-NOT plug a phone jack connector into any RJ-45
port. Use only twisted-pair cables with RJ-45 connectors
that conform with FCC standards.
For 10BASE-T/100BASE-TX connections, a twisted-pair cable
must have two pairs of wires. Each wire pair is identified by two
different colors. For example, one wire might be red and the other,
red with white stripes. Also, an RJ-45 connector must be attached
to both ends of the cable. All RJ-45 ports on the SMC7004FW,
except for the WAN port, support automatic MDI/MDI-X
configuration. This means that you can use straight-through cable
to attach the LAN ports to any network device. However, when
connecting the WAN port to a broadband modem, you will need to
use either straight-through or crossover cable, depending on the
port type used on the modem.
