LAN connector — Plug an RJ-45 network cable into this
connector to connect the unit to a network (via a switch,
hub, or router) or to a single computer.
Activity LED
— This LED blinks to indicate network
activity.
Link LED
— This LED lights to indicate a good network
connection.
Use a straight-through cable to connect to a network, or a crossover cable to
connect directly to a computer.
•
For 10BaseT (10 Mbps) networks, use a CAT 3 or better cable.
•
For 100BaseT (max. 155 Mbps) networks, use a CAT 5 cable.
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.
