5. Lift the two green levers on the top of the expansion card
cage to their upright position to electrically disconnect it
from the system board. This is service position 1.
6. Raise the expansion card cage to engage the built-in catch
that holds the cage up and away from the system board.
This secures the cage and prevents it from damaging
components on the system board. This is service position 2.
Raising the Expansion Card Cage
To reconnect the expansion card cage to the system
board, first ensure that the system board is completely
installed in the chassis. Slightly lift the expansion card
cage and release the built-in catch to lower it into service
position 1; then, rotate the levers to their original
positions to lock the assembly in place.
