Replacing an AC Power Supply Unit During Operations
Step 8 Either replace the power supply unit or cover the empty power supply bay as follows:
• If you are ready to replace the power supply unit, see the “Installing an AC Power Supply Unit
During Operations” section on page 9-6.
• If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco part
number 800-28658-01) over the opening, and secure it with the captive screws.
Installing an AC Power Supply Unit During Operations
After you remove an AC power supply, you can replace it with another power supply or replace it with
a blank plate until another power supply is available. If you need to install a DC power supply unit, see
the “Installing a DC Power Supply Unit During Operations” section on page 9-10.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034
