Managed electrical connectivity systems

A patch panel comprising:

• a frame arrangement defining a plurality of openings;
• a plurality of jack modules disposed at the openings, each jack module defining a port in which a plurality of electrical contacts are disposed, each port defining an insertion axis along which a plug connector can be inserted into the port;
• a circuit board coupled to the frame arrangement, the circuit board extending generally orthogonal to the insertion axes defined by the ports, the circuit board being coupled to a network port;
• a plurality of presence sensors coupled to the circuit board adjacent a corresponding one of the jack modules, each presence sensor including a portion that extends into the corresponding jack module so that the presence sensor is accessible through the port of the corresponding jack module, each presence sensor being configured to detect a presence of a plug connector at the port of the corresponding jack module, each presence sensor being electrically separate from the plurality of electrical contacts of the corresponding jack module, the presence sensors being electrically coupled to the network port;
• and
• a plurality of light indicators visible through the frame arrangement so that each port of the jack modules is associated with one of the light indicators, each light indicator being coupled to the circuit board.
