2 Remove the inner rails from the mounting rails.
Note: The rack mount kit contains a pack of screws, two sets of
side handles, rack brackets and mounting rails. The side handles
are attached to the sides of the server. The rack brackets attach
the mounting rails to the server. The mounting rails allow the
server to slide in and out of the rackmount for maintenance
purposes. Each mounting rail consists of: an inner rail, a middle
slide, and a fixed outer rail. The fixed outer piece is screwed onto
the rack bracket with a M4 x L8 metal screw and nut, the inner rail
is attached to the sides of the server with the #8-32 screws and the
middle sliding piece controlled by a steel ball gearing movement.
(1) Extend the inner rail from the mounting rail until the rail
release latch clicks.
(2) Depress the release latch (1) and slip the inner rail out (2).
(3) Do the same thing to the other mounting rail.
