2-8 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Site Requirement Guidelines
•
Maintain at least a 6-inch (15.25-cm) clearance at the front and back of the router frame
for cooling air intake and warm air exhaust. Avoid placing the router in an overly
congested rack because the heated exhaust air from other equipment can enter the inlet
air vents and cause an overtemperature condition inside the router.
•
Allow at least 19 inches (48-cm) of clearance at the front of the rack for maintenance.
•
Install and use the cable-management bracket included with the router to keep cables
organized and out of the way of line cards, power supplies, and the blower modules.
Consider the equipment and cabling that is already installed in the rack. Ensure that
cables from other equipment will not impair access to the upper or lower card cage, or
require you to disconnect cables unnecessarily to perform equipment maintenance or
upgrades.
•
When mounting the router in a four-post or telco-style rack, be sure to use all of the
screws provided to secure the frame to the rack posts.
