About the Power Bridge
The Power Bridge is a 6/12 Ethernet channel power-feeding device.
This device is designed for use with a 10BaseT/100BaseTx standard
Ethernet network over a standard TIA/EIA-568 Category 5, 6, or 6e
cabling plant. The DC operating power for the data terminal units is fed
through the unused pairs (7/8 and 4/5).
The Power Bridge normally powers devices that are Power over LAN
Enabled or are equipped to receive power over Ethernet. Devices that
are not equipped to receive power over Ethernet require an external
splitter to be powered.
