Rack-Mounting Requirements
•
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: 14.0 in. (35.6 cm) high, 24.5 in. (62.2 cm) deep, and
17.45 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 163.5 lb (74.2 kg). If you stack five fully configured routers in one rack, it must be
capable of supporting about 818 lb (371.0 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 30 in. (76.2 cm) in
front of the router and 24 in. (61 cm) behind the router.
•
The rack or cabinet must have an adequate supply of cooling air.
•
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the router.
•
The router must be installed into a rack that is secured to the building structure.
•
Mount the router 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.
