Figure 4-8 Handling a DC-Input Power Supply
Step 8
If the power supply bay is to remain empty, install a power supply filler plate
over the opening and secure it with the mounting screws. This protects the inner
chassis from dust and prevents accidental contact with live voltage at the rear of
the bay.
Warning Voltage is present on the backplane when the system is operating. To
reduce risk of an electric shock, keep hands and fingers out of the power supply
bays and backplane areas.
