Bridge Power Injector LR
The bridge Power Injector LR delivers 48-VDC power to the bridge. It also
serves as an Ethernet repeater between the internal LAN and bridge and
provides surge protection for any charge that might build up on the Ethernet
cable inner conductor. Power and data are transmitted to the bridge through
two 75Ω coaxial cables. The Power Injector LR receives 48-VDC power from
the power module. It receives Ethernet data from the internal LAN via an
RJ-45 connector. The following illustration shows the bridge power injector
and identifies its interfaces.
