angle.

a. Facing the front of the enclosure, carefully exert even pressure on both sides of the storage enclosure
front, inserting the storage enclosure until the rack ear flanges are flush with the front rack posts.
b. Carefully lower the mechanical lift.
c. Thoroughly examine the rack rails for issues such as bowing, scraping, resistance, or indicators of
misalignment.
6. Complete the following actions to secure the 5U chassis:
a. Remove and set aside the operator's (ops) panel.
b. Thread a lock washer and then a washer onto each of 2 Panhead 10-32 screws.
c. Facing the front of the enclosure, insert a Panhead 10-32 screw with washers into the top and bottom
holes in the ops panel, then hand tighten firmly against front rack post with a Phillips screwdriver.
