Appendix B: SGI 1400 Server Rackmount Installation
Attach the Bracket and Rail Assemblies to the Equipment Rack
Note:
Mounting holes in the verticalrails ofequipment racks are commonly spaced in a
5/8 x 5/8 x 1/2-inch sequence. Perform the following steps carefully; brackets must be
mounted with precision to allow room for the next server you install in a rack. You may
want to mark the appropriate top and bottom holes with a pen or pencil.
1. Remove two screws, and a bar nut from the kit.
2. Select one of the right-angle bracket and rail assemblies that you put together using
the information in “Attach the Center and Large Outer Bar Assemblies” on
page 140.
3. While facing the front or back of the rack, orient the right-angle extension bracket
and rail assembly so that the short side with the four mounting holes is facing
toward the outside edge of the vertical rail.
4. Position the bracket behindthe mountingholes in thevertical rail,see Figure B-4 for
an example.
5. With apencil, mark the topand bottomhole locations ofthe bracketon both sidesof
the vertical rail; no hole numbers are printed on the rail.
6. Insert a screw through the marked top hole in the rail and through the top hole in
the bracket. Place a bar nut on the screw and loosely tighten it. Repeat for the
marked bottom hole.
7. Go to the rear of the system and make sure the bracket and slide-rail assembly is in
horizontal alignment with the front. Repeat the connection procedure from step 6.
8. Install the other right-angle extension brackets and slide rail assembly on the other
side by repeating steps 1–7.
9. Ensure that the brackets and bars are positioned correctly in the rack. Then tighten
all bracket and rail screws firmly (6.0 inch-pounds).
