3COM ETHERNET POWER SOURCE

1 OVERVIEW

The 3Com Ethernet Power Source (EPS) provides power, over existing Ethernet wiring, to devices such as NBX telephones and 3Com wireless access points. The EPS can determine whether an Ethernet device can accept power over the Ethernet cable, and supply power only to those devices capable of accepting it.

The EPS:

Eliminates the need for AC outlets, Uninterrupted Power Supplies (UPS), and AC/DC adapters

Can be used with the 3Com NBX 100 Communications System business telephones and with 3Com’s wireless access points.

Is easy to add to your network
