Prepare The Rack Enclosure - Sun Microsystems Fire 280R Setup And Rackmounting Manual

Prepare the Rack Enclosure

1. Open, and remove if applicable, the front and back doors of the rack enclosure.
See the instructions provided with your rack enclosure.
2. Stabilize the rack enclosure by extending its anti-tip legs or bolting the rack
enclosure securely to the floor.
See the instructions provided with your rack enclosure and read Appendix A.
3. Remove the side panels from the rack enclosure, if applicable.
See the instructions provided with your rack enclosure. Removing the side panels
can improve access to the nuts and screws that you install when securing the system
in the rack enclosure.
4. Measure the depth of the rack enclosure.
See "Vertical Mounting Rail Requirements" in Appendix A for more information
about the range of depths in EIA-compliant industry-standard rack enclosures.
5. Using a felt tip marker and the Rack Buddy, locate and mark the rack rail holes to
use to attach each slide assembly.
The Rack Buddy template can help you locate the rack rail holes to use for each slide
assembly. The Rack Buddy is four rack units (7.0 inches/17.78 cm) or 12 holes tall.
Because the rail holes on a standard rack enclosure are arranged in sets of three
holes spaced 5/8ths, 5/8ths, and 4/8ths of an inch apart, which two holes of the three
you use for attaching a slide assembly varies depending on exactly where in the rack
the system is located.
a. Examine the Rack Buddy. See the next figure.
Two of the middle three pairs of holes are for mounting the slide bracket (you
only use two screws in two of these three holes to attach each slide to the rack).
The top and bottom openings in the template locate the system retainer screws
that hold the system in the rack after it is installed.
