6. Complete the following actions to begin insertion of the storage enclosure into the rack cabinet:
a. Facing the front of the enclosure, carefully exert even pressure on both sides of the storage enclosure front, inserting
the storage enclosure until it locks into the service position with an audible click.
b. Carefully lower the mechanical lift just enough so that the weight of the storage enclosure fully rests on the rails.
c. Thoroughly examine the rack rails for issues such as bowing, scraping, resistance, or indicators of misalignment.
d. Locate and depress both safety lock latches to release the rails.

e. Continue depressing the safety lock latch springs while inserting the storage enclosure into the rack just far enough to
bypass the service position locks.
f. Carefully exert even pressure on both sides of the storage enclosure front.
g. Continue insertion all the way into the rack until the rack mounting flange is flush with the rack ears, locking the
storage enclosure into the storage position. Do not force insertion, because this action could damage the rails.
7. Complete the following actions to
confirm the proper installation of the storage enclosure into the rack cabinet:
a. Gently pull the storage enclosure outward to make sure the storage enclosure slides smoothly on its rails out to service
position and returns smoothly to the storage position.
b. Feel for the smooth, even function of the ball bearings in the ball bearing retainer. Any grinding indicates misalignment
and requires correction, up to obtaining a new rail kit if you identify damaged bearings.
8. Secure the storage enclosure flanges to the rack, fastening the top captive thumbscrew on each side until tight.
Install the CMA and crossbar
The cable management arm (CMA) is essential to the storage enclosure and allows for full extension to the service position. It
also ensures efficient and effective storage enclosure connectivity. The crossbar stabilizes the rear rails, keeps them parallel to
each other, and protects them from inadvertent sideways forces that could damage their function.
