position of the rack unit, or have another drawer unit in the position immediately
above it to prevent the drawer from tipping out of the rack unit while in the service
position.

The stabilizer must be firmly attached to the bottom rear of the rack to prevent
the rack from turning over when the drawers are pulled out of the rack. Do not
pull out or install any drawer or feature if the stabilizer is not attached to the
rack.

1. Do the steps in the power off procedure as detailed in "Stopping the System
