About the Power Bridge
The Power Bridge is a single Ethernet channel power-feeding
device. It is designed for use with a 10BaseT/100BaseTx standard
Ethernet network over a standard TIA/EIA-568 Category 5 (or
higher) 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
Ethernet Enabled; that is, they are equipped to receive power over
Ethernet. Devices that are not equipped to receive power over
Ethernet can be powered by the Power Bridge, but they require an
external splitter.
The Power Bridge has the following features:
•
Remote power feeding of Ethernet terminals
•
A single 10BaseT/100BaseTx data + power combined channel
•
Universal 90 to 264 VAC, 50 to 60 Hz power input
•
Port overload and short-circuit protection
•
Port status LEDs
•
15.4W minimum allowable output power
•
Free-standing or wall-hanging mounting
The Power Bridge also eliminates the need for terminal’s AC
outlets, UPS, and AC/DC adapters.
