Abstract
A tamper detection system utilizes a barrier that includes a bar sized to extend across a rack in an arrangement in which the bar blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the bar being pulled away from the rack enough to decouple a magnet that when magnetically coupled to the rack maintains a switch in a first state against a biasing force of a biasing mechanism urging the switch toward a second state, or such as in response to the bar becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.
