Panel system with managed connectivity
A panel system includes a chassis holding one or more tray arrangements, which are each configured to receive one or more cassettes at two or more bays. The tray arrangements and cassettes cooperate to define a cassette sensor arrangement and a port occupancy sensor arrangement having separate interface points. The cassette sensor arrangement may include electronic memory storing physical layer information about the cassette. All active components of the port occupancy sensor arrangement are disposed on the tray while the electronic memories of the cassette sensor arrangement are stored on the cassettes.

7 . The panel system of claim 6 , wherein the aperture is one of a plurality of apertures defined by the tray base and the portion of the circuit board is one of a plurality of portions that overhang the apertures; and wherein all active components mounted to the circuit board are mounted to the portions that overhang the apertures so that the active components extend into the apertures.
8 . The panel system of claim 6 , wherein the tray base and the circuit board including all components mounted to the circuit board have a total thickness of no more than 2 mm.
9 . The panel system of claim 1 , further comprising:
a first tactile interface member coupled to the circuit board at a first side of the tray arrangement; and
a second tactile interface member coupled to the circuit board at a second side of the tray arrangement, the second side being opposite the first side, the first and second tactile interface members cooperating to enable a user to indicate a selected one of the front ports.
10 . The panel system of claim 9 , further comprising:
a plurality of light indicators disposed at respective ones of the front ports; and
a communications unit mounted at the chassis, the communications unit being communicatively coupled to the circuit board to receive signals from the port occupancy sensor arrangement and the cassette sensor and to send control signals to the light indicators based on input received from the first and second tactile interface members.
11 . The panel of claim 9 , wherein the tray arrangement is movable relative to the chassis between a retracted position and an extended position, wherein the tray arrangement includes a first latching arrangement at the first side of the tray arrangement and a second latching arrangement at the second side of the tray arrangement, the first and second latching arrangements releasably retaining the tray arrangement relative to the chassis in one of the retracted and extended positions, wherein the first tactile interface member is disposed at the first latching arrangement and the second tactile interface member is disposed at the second latching arrangement.
12 . The panel system of claim 1 , further comprising:
