Rack-Mounting Guidelines
The router can be mounted in most 2-post, 4-post, or telco-type 19-inch
equipment racks that comply with the Electronics Industries Association (EIA)
standard for equipment racks (EIA-310-D). The rack must have at least two posts
with mounting flanges to mount the router chassis. The distance between the
center lines of the mounting holes on the two mounting posts must be 18.31 inches
± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the
router is suitable for most 19-inch equipment racks or telco-style frames.
Figure 2-2 shows examples of typical 2-post, 4-post, and telco-type equipment
racks.
