Allow up to four devices to be connected to the network.
A green LED indicates connection status when a device is
using a particular port.
Port number 1 is also a power-forwarding port; it can be
used with any standard networking device as well as to
power a VoIP telephone on a network that uses IEEE
802.3af-compatible Power Over Ethernet. An additional
LED indicates when the port is forwarding power to a
device connected to that port.
Can be fitted with an adapter plate, which can be installed
with up to two pass-through ports.
Can be used for voice or other networking applications.
The port bypasses the functionality of the switch, allowing
you to set up a connection to a separate network segment
or to connect to an analog or digital PBX telephone.
The adapter plates are available from 3Com. However, you
must purchase the connectors from the manufacturer. See
"Installing the Adapter Plate and Pass-Through Ports" on
page 8 for more information.

Ethernet.
