The rack must be strong enough to support the weight of the fully configured router, up to 163.5 lb
(74.2 kg). If you stack five fully configured routers in one rack, it must be capable of supporting up to 818 lb
(371.0 kg).

Spacing of Mounting Bracket Holes

The router can be mounted in any rack that provides holes or hole patterns spaced at 1 U (1.75 in.)
increments. The mounting brackets used to attach the chassis to a rack are designed to fasten to holes
spaced at those distances.

Connection to 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.
