7. Insert the equipment, with inner members attached in 5, into the bracket assemblies by inserting the top and
bottom edges of the inner members into the top and bottom curved tracks of the front members and sliding
the equipment into the rack (see figure at right). Ends of inner members are tapered to allow the rear of the
equipment to be angled upward before insertion, if space allows.
Then the rear, bottom edges of the inner members can be placed into the front edge of the bottom tracks and
the front of the equipment can be tipped up so they are level to insert the top edges of the inner members
before sliding the equipment into the rack (see figure above right). The equipment should move smoothly into
the bracket assemblies. If it does not, recheck the alignment of the front and rear members from 23. on page26.
8. Secure the front of the equipment to the rack mounting rails to prevent the equipment from sliding out of
position. If securing holes are provided on the front of the equipment that align with the center holes on the
return flange of the front members, you can use the four extra M5 screws provided in the kit to secure the
equipment. Otherwise, the equipment should be secured to the front of the rack with four customer-supplied
fasteners.
