Rack-Mounting Considerations

The Cisco uBR10012 router should be rack-mounted for proper operation and maintenance. The rack-mounting hardware included with chassis is suitable for standard 19-inch equipment racks and telco-type racks. Optional hardware is available from third-party vendors for mounting in a 23-inch equipment rack.

Mounting Guidelines

Warning The chassis should be mounted on a rack that is permanently affixed to the building. Statement 1049

When planning your rack installation, consider the following guidelines:

•Install the Cisco uBR10012 router in an open rack whenever possible.

Caution To prevent overheating, never install the chassis in an enclosed rack or room that is not properly ventilated or air conditioned.

•Allow sufficient clearance around the rack for maintenance. You need 24 in. (61 cm) of clearance to remove and replace system components.

Caution To prevent the rack from tipping when installing the router in telco racks, ensure that the rack is bolted to the floor and, if necessary, anchored with appropriate fixtures.

•If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

•Always install heavier equipment in the lower half of a rack to maintain a low center of gravity and prevent the rack from falling over.

•When mounting this unit in a partially filled rack, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.

Note This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

•If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis. Use the rack-mount kit designed for the Cisco uBR10012 router.

•To mount the chassis between two 19-inch posts or rails, the inner clearance (the width between the inner sides of the two posts or rails) must be at least 17.3 in. (44 cm).

Note The height of the chassis is 31.25 in. (79.4 cm).

•When mounting the chassis in 4-post or telco racks, be sure to use all the screws and brackets provided to secure the chassis to the rack posts.

•Install the forward rack-mount brackets before you install the chassis in the rack; and then install the rear brackets.
