Physical Characteristics
Be familiar with the physical characteristics of the Cisco Catalyst 8300 Series Edge Platforms to assist you
in placing the system in the proper location.
For more information on the physical characteristics of Cisco Catalyst 8300 Series Edge Platforms, refer to
the datasheet for the Cisco Catalyst 8300 Series Edge Platforms.
Rack Requirements
The Cisco Catalyst 8300 Series Edge Platforms include brackets for use with a 19-inch rack or, if specified
in your order, optional larger brackets for use with a 23-inch rack.
The following information can 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 device
generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat
generated by equipment at the bottom of the rack can be drawn upward into the intake ports of the
equipment above it.
• If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
Router Environmental Requirements
Cisco Catalyst 8300 Series Edge Platforms can be placed on a desktop or installed 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 front and rear
panels of the router.
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 to 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 the ESD-prevention procedures to avoid damage to equipment. Damage from static
discharge can cause immediate or intermittent equipment failure.
