Methods and apparatus for enabling internal circuitry associated with a device to be efficiently replaced in an operating environment for the device are disclosed. According to one aspect of the present invention, a device includes an enclosure that defines an interior of the device, and a circuit arrangement that is located in the interior. A data port interface is located in the interior, and the device also includes a receptacle and a protection circuitry arrangement. The receptacle is coupled to the circuit arrangement, and the protection circuitry arrangement provides protection to the circuit arrangement. The protection circuitry arrangement has an interface that is removably coupled to the receptacle such that at least a portion of the protection circuitry arrangement is contained in the interior of the device.
