CAUTION: The system requires one power supply for normal operation. On power-redundant
systems, remove and replace only one power supply at a time in a system that is powered on.
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.
Steps
1.
Disconnect the power cable from the power source and from the power supply unit you intend to
remove and remove the cables from the strap.
2.
Press the release latch and slide the power supply unit out of the chassis.
