Installing Blank Faceplates over Empty HWIC Slots
All interface card slots must be covered by interface cards or blank faceplates for cooling, electromagnetic interference (EMI) reduction, and safety.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
