Router Clearance Requirements
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. You must allow sufficient clearance around the installed chassis for cooling
and maintenance. See Figure 2 on page 5.
If you are mounting an MX10003 in a rack with other equipment, ensure that the exhaust
from the other equipment does not blow into the intake vents of the MX10003 chassis.

Router Cooling and Airflow Requirements
•
The router has front-to-back or airflow out (AFO) cooling system. Air is pulled through
the front of the chassis toward the fan tray, from where it is exhausted out of the
system. The power supplies are self-cooling and are located in the rear of the router.
See Figure 3 on page 6.
•
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 routers.
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.
