the system board (

Caution – The power supplies contain pinch points. Be very careful when opening
and closing the levers on the power supplies. Keep your hands and fingers away
from the base and sides of the levers. For more information about these pinch points,
refer to the power supply labels.
5. Insert the two power supply units in the power supply unit bays.
6. Slide each power supply unit into the server until you feel it engage with the
power distribution board.
Ensure that the lever does not return to a vertical position until the power supply
unit engages with the power distribution board. If the lever returns to vertical, the
power supply unit does not engage correctly.

Returning the lever to a vertical position engages the power supply unit with the
power distribution board inside the server.
