Step 1: Prepare the Site for Installation
Prepare your site for installation by observing the following guidelines:
•
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 chassis's external dimensions: 1.7 in.
(4.4 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44 cm) wide. The outer edges of the mounting brackets
extend the width to 19.2 in. (48.7 cm).
•
One person must be available to lift the router while another secures the router to the rack.
•
The rack must be strong enough to support the weight of the fully configured router, up to 7 lb (3.2 kg).
•
For service personnel to remove and install hardware components, allow at least 2.16 in. (5.5 cm) in
front of 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.
•
When deploying the router in environments where the router may operate between 131° F (55° C) and
149° F (65° C), allow a 1 rack unit (U) gap above and below the router.
•
When installing the router in a cabinet, ensure that the bottom of the cabinet is closed and there is no
opening.
•
You must install the router 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.
•
Install the router only in restricted areas, such as dedicated equipment rooms and equipment closets, in
accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.
