Figure 1: Rack Clearance and Router Dimensions
- You can install the router in a four-post rack or cabinet
or an open-frame rack.
- The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 20.75 in. (52.71 cm) high, 24.3 in. (61.7 cm) deep, and 17.43 in. (44.3 cm) wide.
The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm).
- The rack must be strong enough to support the weight of the fully
configured router, up to 225 lb (102.1 kg). If you stack four fully
configured routers in one rack, it must be capable of supporting about 900 lb (408.4 kg).
- For service personnel to remove and install hardware components,
there must be adequate space at the front and back of the router. Allow
at least 24 in. (61.0 cm) both in front of and behind the router.

- The router must be installed into a rack that is secured to the
- The router should be mounted at the bottom of the rack if it is
the only unit in the rack.
- When mounting the router in a partially filled rack, load the
rack from the bottom to the top with the heaviest component at the bottom
of the rack.
