1
If you have unlatched the cable management arm, relatch it. For information about the cable management arm, see the system’s rack
documentation at

.
2
Connect the power cable to the PSU, and plug the cable into a power outlet.
CAUTION:
When connecting the power cable to the PSU, secure the cable to the PSU with the strap.
NOTE:
When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for the 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 in the system with different connectors used to connect
different components or peripherals of the system. A system board provides the electrical connections to the components in the system to
communicate.
Removing the system board
Prerequisites
CAUTION:
If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create a
recovery key during program or System Setup. Be sure to create and safely store this recovery key. If you replace this system
board, you must supply the recovery key when you restart your system or program before you can access the encrypted data on
your drives.
CAUTION:
Do not attempt to remove the TPM plug-in module from the system board. After the TPM plug-in module is installed,
it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in module breaks the
cryptographic binding, and it cannot be re-installed or installed on another system board.
