3.4.2. Ethernet
The Ethernet ports are on the front of the unit and are marked LAN 1 and LAN 2. Each
port has a LED indicating the connection speed and a LED indicating activity. Both ports
are capable of auto-negotiation, meaning cross-over cables are not required. The Ethernet
ports are switched, allowing more than one Ethernet device to be connected to the unit at
one time.
