Rack Requirements
The following information will 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.
• 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.
Router Environmental Requirements
Mount the Cisco IR8340 routers in a rack. 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 power supply side and cable side panels of the router.
Allow at least one rack unit of vertical space above the router.
Note
When planning your site layout and equipment locations, refer to
General Site Requirements, on page 16
. 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
Preventing Electrostatic Discharge Damage, on
to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent
equipment failure.
• Ensure that the chassis cover and module cable side panels are secure. All empty interface card slots and
power supply bays must have filler panels installed.
• 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.
Power Guidelines and Requirements
Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install
a power conditioner if necessary.
The AC power supply includes the autoselect feature for either 110 V or 220 V operation.
