Clearance Requirements for Airflow and Hardware Maintenance for the
MX2010 Router
When planning the installation site, you need to allow sufficient clearance around the rack for airflow and
hardware maintenance. The clearance requirements vary, depending on whether the MX2010 uses AC or
DC power and whether the MX2010 has a standard or extended cable manager.
NOTE: There are no additional clearance requirements to accommodate the depth of the MX2010
power distribution modules (PDMs) and power supply modules (PSMs); they are within
specification.
When planning for adequate clearance for airflow and hardware maintenance, keep the following in mind:
For the cooling system to function properly, the airflow around the chassis must be unrestricted.
Airflow must always be from front to back with respect to the rack. This ensures that fresh air from the
front of the rack is supplied to the inlets, and the exhaust exits the rear of the rack.
Check the cables to ensure there is no air leakage.
There must be a minimum of 34-U of usable rack space when you install the MX2010.
For service personnel to remove and install hardware components, there must be adequate space at the
front and back of the router. At least 36 in. (91.44 cm) is required both in front of and behind the router.

Clearance Requirements for MX2010 Routers with Standard Cable Managers

The clearance requirements for the MX2010 with standard cable managers differ depending on whether
the MX2010 is using AC or DC power.
and clearance requirements for AC- and DC-powered MX2010 routers with standard cable managers.
