Removing a power supply

About this task
Caution:
To remove all electrical current from the server, ensure that all power cords are disconnected
from the power source. The power control button on the server does not turn off the electrical
current supplied to the server. The server also might have more than one power cord.
Caution:
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this
label attached. These components do not contain any serviceable parts. If you suspect a
problem with one of these parts, replace the power supply.
Important:
During normal operation, each power supply bay must contain either a power supply or power
supply filler for proper cooling.
Important:
Always use an electrostatic-discharge wrist strap or other grounding system when you work
inside the server. For more information, see
