2. Position the chassis with the lift such that the inner rails are lined up perfectly with the middle rails. The end of
both inner rails should be equidistant from the rack face. To make adjustments to the alignment, shift the
chassis on the left until alignment of both sides is adequate.

3. Keeping the chassis stationary, pull the middle rails forward onto the inner rails, ensuring full engagement of
the inner rails onto the middle slide track. Middle slides should slide freely and smoothly onto inner rails.
Difficult middle slide movement during this step typically indicates misalignment.
4. Middle rails will eventually "click" into place as the service position locks engage. Ensure both sides engage at
the same time, and both inner rails are fully engaged on their respective middle slide tracks.
5. Carefully and slowly lower the mechanical lift 2"– 3" so that the weight of the chassis now fully rests on the rail
kit. Keep the lift elevation 2"– 3" below the chassis elevation until the enclosure is fully installed in the rack.
This is a safety measure in case the rails are not seated properly, or another mechanical/integration failure
occurs.
6. Locate the inner slide lock springs on both the left and right rail kits, and depress both to disengage the service
protection lock. Continue depressing springs while inserting the chassis far enough to bypass the locks on both
sides.

7. Continue inserting the chassis all the way into the rack, ensuring the chassis ears are coincident with the rack
mounting flanges.
