Chapter 4 Removal and Replacement Procedures
Step 6 Grasp the power supply handle with one hand. Place your other hand underneath as you slowly pull the
power supply out of the chassis power supply bay (see
Figure 4-14
Step 7 If the chassis power supply bay is to remain empty, install a blank power supply filler plate
(WS-C4KE-PS-CVR) over the opening and secure it with the mounting screws. The blank power supply
filler plate protects the inner chassis from dust and prevents accidental contact with the live voltage at
the rear of the bay.
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
