Router Placement

You can mount the Cisco MWR 1941-DC router in a 19-inch rack that conforms to EIA-310-D
specification (the inside width of the rack should be 17.72 to 17.80 inches per the EIA-310-D
specification). The MWR 1941-DC router requires this minimum width and occupies 1U (1.75 inches)
of vertical space.

The following information will help you plan your equipment rack configuration:

• Allow clearance around the rack for maintenance.

• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each

router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports
of the equipment above.

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or

exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated
into the rack.

• Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through

the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can
be found by experimenting with different configurations.

• When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the

equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to
allow the router under test a maximum of cooling air and clean power.

Rack Mounting the Chassis

You can mount the Cisco MWR 1941-DC router in a 19-inch rack that conforms to EIA-310-D
specification (the inside width of the rack should be 17.72 to 17.80 inches per the EIA-310-D

of vertical space.

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:

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

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.

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