Replacing Power Supplies and Redundant Power Supplies

The Cisco ISR 4451-Xs have replaceable power supply modules and some have an optional external redundant power supply (RPS). All of the internal power supplies for the Cisco ISR 4451-Xs are modular and do not have internal cabling. These modular power supplies can be removed or installed using only a screwdriver.

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
