A method of monitoring connection status of wiring within a marshalling cabinet includes generating, by a switch including a first portion and a second portion, a socket connection signal when the switch is closed. The switch closes when a wire harness including the second switch portion is inserted within a socket of a terminal block including the first switch portion by a predetermined amount. The wire harness includes wire harness pins in communication with factory wiring of an industrial control system and the terminal block includes terminal block pins in communication with field wiring of the control system. The method also includes receiving the socket connection signal and determining a socket connection status. The status is determined to be connected when the socket connection signal is received by the processor and determined to be disconnected status absent receipt of the connection signal. The determined connection status is also output.

This disclosure relates to a structure that conveniently and easily releases computer components from a supporting structure. A typical computer component would be a PCIe card within a GPU tray. The disclosed structure does not require the use of tools to release computer components, and can be used where computer components ordinarily cannot be released due to limitations of space. The structure lifts the computer component to a height where the computer component can be easily grasped by human fingers for removal of the component.
