mounting the rails is a complex procedure. to install the rack rails correctly, you must read, and then perform each procedure step in the order given. failure to perform each step in the order given may cause rail failure.
to install the rack-mounting hardware into the rack, do the following:
1. locate the rack-mounting hardware kit, rack-mounting template, and the system rails that were shipped with your system.
a. the system rails are front-to-back and left-to-right side dependent when you are standing in the front of and facing the rack. the rails can be identified by the two large latch assemblies on the rear of each rail. see the following illustration to orient yourself to the left and right rail assemblies.
2. remove the front and rear rack doors if necessary. for 7014 model t00 and t42 racks, refer to 7014 model t00 and t42 rack installation and service guide, order number sa38-0577, for information about removing the rack doors.
3. locate the rack-mounting template. if you do not have a rack-mounting template, go to substep 6. 4. using the rack-mounting template, determine where in the rack to place the system. make note of the electronics industries association (eia) location number.
the rack-mounting template has printed illustrations located on the front of the template. each illustration is designed to aid in identifying the eia location holes used when planning to populate your rack. do not use the rack-mounting template without reading and understanding the following substeps. each step must be completed in its entirety.
5. note the following when using the rack-mounting template:
1 each black or white unit on the template is equal to 1 eia unit.
2 each eia unit consists of three holes.
3 the eia units illustrated on the template must be aligned with the eia units located on the rack.
4 it is not necessary to align like-colored eia units. for example, a black eia unit illustrated on the rack-mounting template does not have to be aligned with a black eia unit located on the rack. a black eia unit on the rack-mounting template can be aligned with a white eia unit located on the rack. see the following illustration.
to use the rack-mounting template, do the following:
a. remove the protective coating from each adhesive strip located on the back of the rack-mounting template. lightly press the template into position on the rack. ensure that both the left and right sides are at the corresponding eia locations.
the tabs on each side of the template show a notch to indicate the proper spacing between the front flanges.
b. locate the four dots, two printed on each side of the template. place a self-adhesive dot directly across from the template’s printed dots on or near the rack’s eia numbering strip. you will be using these dots to aid in correctly positioning the rail-alignment pins located on the front of each rail. see the illustration below.
c. remove the rack-mounting template from the front of the rack. the front of your rack should now contain four self-adhesive dots.
d. mount the rack-mounting template to the rack’s rear eia flange. place the rack-mounting template at the same eia-numbered location that was used on the front of the rack.
e. wrap a self-adhesive dot directly across from the template’s printed dots. ensure that a portion of the self-adhesive dot wraps around the rack’s flange so that it can be seen from the front of the rack.
f. remove the rack-mounting template from the rear of the rack. the rear of your rack should now contain four self-adhesive dots that have been partially wrapped around the rack’s rear flanges.
the following illustration shows one eia unit and four eia units. depending on the rack manufacturer, the eia units may be separated either by color or by a line. note the holes along the rail are not evenly spaced. if your rack has no color or line separation between eia units, assume that each eia unit begins where the hole spacing is closest together.
6. if you do not have a rack-mounting template, do the following:
a. determine where in the rack to place the system. the system you are about to install measures 4 eia units high. make note of the eia location number.
an eia unit on your rack consists of a grouping of three holes. see the figure above.
b. facing the front of the rack and working from the right side, place a supplied self-adhesive dot next to the top hole of the bottom eia unit.
the self-adhesive dots are used to aid in identifying locations on the rack. if you no longer have any of the dots, use some other form of marking tool to aid you in identifying hole locations (for example, tape, a marker, or pencil).
c. place another self-adhesive dot next to the top hole of the above eia unit.
if you are counting the holes, begin with the hole identified by the first dot and count up four holes. place the second dot next to the fourth hole.
d. repeat substeps 6a through 6d for the corresponding holes located on the left side of the rack.
7. before installing the system rail assemblies into your rack, you must first preset the rails to allow correct assembly with the rack and system unit. do the following:
a. unpack the system rail assemblies.
b. fully extend each rail assembly.
c. lock the rear latch assemblies to the open position using the latch release tab.
8. position yourself at the front of the rack.
9. facing the rack, insert the rail’s rear-alignment pins into the rack’s rear flange holes identified by the self-adhesive placement dots previously installed.
10. press the release tab. this action will cause the rear latch assembly to close on the flange. ensure that the pins have passed through the proper holes in the rear flange to verify proper alignment.
11. insert the rail’s front-alignment pin into the rack front flange hole identified by the self-adhesive placement dot previously installed. ensure that the eia location is the same from front to back and the rails are level from front to rear.
12. loosely thread one of the rail-retaining screws into the rail’s front screw hole. the screw hole is located one position above the front-alignment pin.
13. position yourself at the rear of the rack. loosely thread one of the rail-retaining screws into the rail’s rear screw hole. the screw hole is located between the two rear alignment pins. return to the front of the rack.
14. attach the drawer latch bracket by doing the following:
a. locate a drawer latch bracket and its screw.
b. align the square peg on the back of the bracket with the square hole in the front rail assembly.
c. place the hole in the bracket over the screw hole and loosely thread the screw into place. the screw hole is located one position above the front rail-retaining screw.
15. before continuing to the next step, be sure to read and understand the following caution notices:
mounting the rails is a complex procedure. to install the rack rails correctly, you must read, and then perform each procedure step in the order given. failure to perform each step in the order given may cause rail failure.
the stabilizer must be firmly attached to the bottom rear of the rack to prevent the rack from turning over when the drawers are pulled out of the rack. do not pull out or install any drawer or feature if the stabilizer is not attached to the rack.
