The CGR's chassis hardware features Door Sensor located inside the door, see the highlighted
red item. The Door Sensor is a pressure-sensitive alarm switch that detects the opening and
closing of the CGR's door and alerts the Field Network Director (FND)/ Cisco Grid Network
Management System (CGNMS) FND/CGNMS operator to a potential security breach. When
the switch detects the door has been opened or closed, it sends an event message to the CGR,
which is stored in the router log file.
