NOTE: If only one power supply is installed, it must be installed in the PS1 power
supply bay.
Removing a Power Supply
CAUTION: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
CAUTION: The system requires one power supply to operate the system normally.
Remove and replace only one power supply at a time in a system that is powered
on.
1
Disconnect the power cable from the power source.
2
Disconnect the power cable from the power supply and remove the system
cables from the Velcro straps.
NOTE: You may have to unlatch and lift the optional cable management arm if
it interferes with power-supply removal. For information about the cable
management arm, see the system’s rack documentation.
3
Press the lever release latch and slide the power supply out of the chassis.
See Figure 3-11.
NOTE: Install a power supply blank if you are not replacing the power supply.
See "Installing the Power Supply Blank" on page 80.
