Systems and methods for maintaining and servicing a data processing system or “computer system,” including rack enclosures housing multiple servers, desktop computers, and controllers for industrial automation. According to one aspect, touch-activated circuitry is configured with a computer system to control power and data flow to a component port and facilitate hot-swapping of components, such as PCI cards, fans, and hard drives. The component port, such as a PCI slot, electronically interfaces with a removable electronic component, such as a PCI card. A user activates the touch-activated circuitry by touching one or more contact points. Touching the contact points thereby initiate a shut-down sequence of a component driver or other software and then powers down the electronic port so that the electronic component may be safely removed.
