Only use the power adapter that is supplied with this Gateway. Do not use any
other adapter.
6 Ethernet Cable/DSL port
Use the supplied patch cable to connect the Gateway to the 10BASE-T port on
your cable or DSL modem. This port will only operate at 10Mbps in half-duplex
mode.

Use suitable cable with RJ-45 connectors. You can connect your Gateway to a
computer, or to any other piece of equipment that has an Ethernet connection
(for example, a hub or a switch). All ports will automatically detect the correct
speed (10Mbps or 100Mbps) and duplex mode. Additionally, all ports will be
automatically configured for MDI or MDI-X (straight-through or crossover)
operation.
