Spacing of Mounting Bracket Holes

The router can be mounted in any four-post rack or cabinet that provides holes or hole patterns spaced
at 1 U (1.75 in.) increments. The front-mount flanges used to attach the chassis to a rack are designed to
fasten to holes spaced at those distances.

Connection to the Building Structure

Always secure the rack to the structure of the building. If your geographical area is subject to earthquakes,
bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.
