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 AC-IG1004, 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.
Note that if you are using the Uplink port on the AC-IG1008, you cannot use the
crossover port on Port 8.
