SPECIFICATIONS

The Q7751A Router is a two-piece design allowing prewiring and cable testing prior to installing the electronic component. The front panel includes a printed circuit board (PCB) with active electronics. The front panel also has a service switch, a power/wink LED, an activity LED, and two network connectors. Network and power are connected to screw terminals located on a type 2 base plate where the router is plugged. Wiring is never directly connected to a router.
