RackPlumber is Patch cable remote extension
Pair of RackPlumber connected via ethernet cables to allow for simple connections between large or spread-out cases.
2 connectors are available - On the front panel to connect between 2 racks and on the back of the module to create "shortcuts" inside big rack.
It is possible to chain few RackPlumbers to achieve passive mult.
Jack LEDs monitor if there is signal in each input, those leds bypassed when patch plugged in to prevent voltage drop.
These merchants probably sell this module. Huh?
