Step 1: Prepare the Site for MX104 Router Installation
Prepare your site for MX104 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: 6.125 in. or (15.55 cm) high, 9.5 in. (24.13 cm) deep, and 17.5 in. (44.5 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 32 lb (14.5 kg).
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. Allow at least 6 in. (15.2 cm) of clearance between side-cooled devices.
Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing
surface such as a wall.
•
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.
•
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.
