Description
Recovery has failed. This typically happens so quickly
after recovery is initiated that it sounds like a 2-4
beep code.
CPU1 socket is empty, or sockets are populated
incorrectly – CPU1 must be populated before CPU2.
MSID mismatch occurs if a processor is installed into
a system board that has incompatible power
capabilities.
DC power unexpectedly lost (power good dropout) –
Power unit sensors report power unit failure offset.
Power good assertion timeout – Power unit sensors
report soft power control failure offset.
VR controller DC power on sequence not completed
in time.
The system does not power on or unexpectedly
powers off and a Power Supply Unit (PSU) is present
that is an incompatible model with one or more other
PSUs in the system.
