in the near future. In a basic stand-alone configuration, it can provide direct full-
duplex connections for up to 10 workstations or servers. You can easily build on
this basic configuration, adding direct full-duplex connections to workstations or
servers. When the time comes for further expansion, just connect to another
hub or switch using one of the Gigabit Ethernet ports built into the front panel,
or a Gigabit Ethernet port on a plug-in SFP transceiver.
In the figure below, the switch is operating as a collapsed backbone for a small
LAN. It is providing dedicated 100 Mbps full-duplex connections to workstations
and 1000 Mbps full-duplex connections to power users, and 1000 Mbps full-
duplex connections to servers.

POE CONNECTIONS
The switch is an excellent choice for supplying power to connected PoE devices
such as web cameras, IP telephones, or access points.
The eight RJ-45 ports on the switch can provide up to 30 W of power to a
connected device. The switch can supply 9.37 W simultaneously to eight PoE
devices among the eight Gigabit Ethernet ports, or 30 W simultanesously to two
connected PoE devices. The total power cannot exceed the 75 W PoE power
budget.
