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

The high-speed WAN interface card (HWIC) hardware kit for Cisco 3800 series routers contains four
blank faceplates. Each blank faceplate covers one single-wide HWIC slot.
Figure 42 and Figure 43 show a blank faceplate for an interface card slot.
