The following information can help you plan your equipment rack configuration:
• Allow clearance around the rack for maintenance.
• Allow at least one rack unit of vertical space between routers; more clearance is required when stacking

Note
• 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 it.
• 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 in the rack.
Router Environmental Requirements
Cisco 1100 Series ISRs can be placed on a desktop, installed in a rack, or mounted on a wall. The location of
your router and the layout of your equipment rack or wiring room are extremely important considerations for
proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can
cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear
panels of the router.
Only C111x Series support rack installation and DIN Rail mounting.
Note
When planning your site layout and equipment locations, refer to the General Site Requirements , section. If
you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment,
these precautions and recommendations may help you isolate the cause of failure and prevent future problems.
• Ensure that the room where your router operates has adequate air circulation. Electrical equipment
generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to
acceptable operating temperatures.
• Always follow ESD-prevention procedures described in the Preventing Electrostatic Discharge Damage
to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent
equipment failure.
• 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.
