When you remove or install a fixed power supply, observe the following
precautions.
Statement 8
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. There are no serviceable parts inside these
components. If you suspect a problem with one of these parts, contact a service
technician.
To remove a fixed power supply, complete the following steps:
Note:
v If one fixed power supply is installed in the server, you must turn off the server
before removing the power supply.
v You must install the fan assembly before removing or installing the power
supply.
1. Read the safety information that begins in Safety and “Installation guidelines”
on page 36.
Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which might
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when you work
inside the server with the power on.
2. If only one power supply is installed, turn off the server and peripheral devices
and disconnect all power cords.
3. Loosen 4 screws from the rear side of the server and pull the fixed power
supply out of the server as the illustration showed.
