Installing the Slide Assembly in the Rack 15
Procedure (continued)
2If the rack retma rail holes are not threaded, attach the appropriate
threaded clips to the holes that correspond to:
‡the mounting bracket tabs (front and back)
‡the locking bracket tabs (front only)
‡the temporary support screws (front and back)
3Insert a temporary support screw into each retma rail, just below
the desired position of the slide assembly bracket.
Use four of the 10-32 x 3/4 in. slide mounting screws as temporary
support screws.
4Make sure the support screws are level with one another.
Leave the screws extended out of the retma rails at least 0.625 in.
(16 mm) so they will support the slide assembly mounting brackets
during installation.
Installing the Slide
Assembly in the Rack 9
To install the slide assembly in the rack (see figure 10 on page 16):
Procedure
1Loosen (but do not remove) the nuts holding the rear mounting
brackets to the slide assembly.
2Measure the depth of the rack, from the outside edge of the front
retma rail to the outside edge of the rear retma rail.
3Adjust the rear mounting brackets so that the distance from the
front mounting brackets to the rear mounting brackets is slightly
greater than the depth of the rack.
4Insert the slide assembly into the rack:
aLift the slide assembly and tilt it sideways.
bInsert the back end of the slide assembly into the front of the
rack, keeping the slide assembly above the temporary support
screws.
cWhen the rear brackets clear the rear retma rails, turn the slide
assembly right side up.
dPlace the slide assembly in the rack so that each bracket rests
on a temporary support screw.
5Secure the front mounting brackets to the front retma rails, using
four 10-32 x 3/4 in. screws from the accessories kit.
6Adjust the rear mounting brackets so they are flush with the
outside of the rear retma rails.
