The FUPP is designed to be "plug and play," meaning that if it is damaged or dysfunctional, it is pulled out in its entirety and replaced with a new one.
On the battlefield, this is thought to be a more efficient way of repairing systems. In a case like this, the defective FUPP will usually be taken away to a maintenance area. In combat zones, replacement FUPPs are carried around by heavy trucks, or possibly delivered by aircraft.
