4.4.2 Positioning and Attaching Front- and Rear-Mount 19-in. EIA Rails
Front- and rear-mount, 19-in., EIA rails are installed in 600-mm wide racks at the factory at 29.13 in.
(740 mm). They attach to the cabinet frame at the top and bottom, in the center to the support member
using M6x12 Torx-head screw into a rail-adjustment bracket.
In 800-mm wide racks, 19-in. EIA rails are attached using node brackets. The node brackets attach to the
top and bottom of the DCF frame and in the center to the support member. The EIA rails move as a unit if
they need to be repositioned.
To position the EIA rails on 600-mm cabinets:
1.
Determine the installation location of the EIA rails.
2. Loosen the M6x12 screws in the rail-adjustment brackets, securing the 19" EIA rails to the frame
member as shown in the following figure.
NOTE: Rails in both the 600- and 800-mm wide racks are attached at the top, center and bottom.
3. Slide the rail-adjustment brackets up or down, depending on their orientation in the rack.
4. Slide the EIA rail to the desired position, making sure to keep it square. The frame member and
support have small holes spaced on 6.35-mm centers to help properly position the rails.
NOTE: The front and rear 19-in. EIA rails must be kept at a 90-degree angle to the upper and lower
frame members. The left- and right-front vertical rails must be the same distance from the front of the
rack. The left- and right-rear vertical rails must be the same distance from the rear of the rack. If these
conditions are not met, equipment and optional features will be difficult to install.
