Side Bracket With Alignment Marks
b. On one side, insert the first two screws through the side bracket slots above and
below the alignment mark into the rear-most threaded holes in the enclosure.
For example, to mount the enclosure in a 27-inch deep rack, position the side
bracket so that the 27-inch alignment mark is aligned with the rear-most threaded
holes in the enclosure.
c. Insert up to six more screws through the side bracket slots into the other threaded
holes in the side of the enclosure.
d. Repeat Step b and Step c to attach the other side bracket to the enclosure.
6. Attach the rear brackets to the rear vertical posts of the rack. Use two screws and
two washers, if required, to attach each bracket to a post.
Use the appropriate fasteners for the posts; either:
■
Four #10-32 x 1 panhead screws with #10 washers
■
Four #10 x 5/8 truss screws
■
Four 5-mm panhead screws with #10 washers
■
Four 6-mm panhead screws (no washers required)
7. Lift the enclosure and slide the side brackets into the rear brackets, which are
attached to the rear posts.
Adjust the depth of the side brackets so that the slots nearest the ends of the
side
brackets
align with the four PEM nuts in the
rear brackets
.
8. Attach each side bracket to a rear bracket using #8-32 x 1/4 screws (four per
bracket).
9. Make sure that the enclosure is level and then secure the mounting ears on the front
of the enclosure to the rack face. Use two screws for each ear.
Use the appropriate screws for the rack; either:
■
Four #10-32 x 1 panhead screws
■
Four #10 x 5/8 truss screws
■
Four 5-mm panhead screws
■
Four 6-mm socket cap screws
10. Tighten the screws in the side brackets.
11. If you removed modules from the enclosure, reinsert them.
