9. Tighten all eight M3 screws, securing the inner rail to the system drawer side.
10. Push the system drawer about halfway back into the rack. Use a screwdriver or similar tool to tighten
the front four M7 16-mm screws that secure the system rail assemblies to the rack's front flange.
11. Push the system drawer completely into the rack. Use a screwdriver or similar tool to tighten the rear
four M7 16-mm screws that secure the system rail assemblies to the rack's rear flange.
Note: After the system rail assemblies are installed, do not extend each rail section past its safety
release latch. The safety release latches stop the rails from overextending and separating. This
action prevents the system drawer from being accidentally pulled out too far and dropped.
12. Tighten the two M3 screws that secure each rail-length adjusting plate.
13. Slowly slide the system drawer back and forth on the rails, watching for any signs of binding.
14. For additional stability needed when transporting the rack, fasten the system drawer to the rack
enclosure by inserting an M8 16-mm thumbscrew through the bezel and chassis bracket, and
screwing it to the rack flange with a screw clip nut.
