Connect the power cable to the PSU and plug the cable into a power outlet.
CAUTION: When connecting the power cable, secure the cable with the strap.

system to recognize the PSU and determine its status. The PSU redundancy may not occur until
discovery is complete. Wait until the new PSU is discovered and enabled before you remove the
other PSU. The PSU status indicator turns green to signify that the PSU is functioning properly.

System board
A system board (also known as the motherboard) is the main printed circuit board found in systems. The
system board allows communication between many of the crucial electronic components of the system,
such as the central processing unit (CPU) and memory, and also provides connectors for other
peripherals. Unlike a backplane, a system board contains significant number of sub-systems such as the
processor expansion cards, and other components.
