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.
