Note
You have already unpacked your chassis and read all the site requirements for your new equipment.
Proceed with the installation.
General Rack Installation Guidelines
When planning your rack installation, consider the following guidelines:
•
The Cisco ASR 1002 Router requires a minimum of 3.5 inches or 8.9 cm rack units of vertical rack
space. Measure the proposed rack location before mounting the chassis in the rack.
•
Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rack-mount installation, remove the power
strip before installing the chassis, and then replace it after the chassis is installed.
•
Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it
back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving
cards, connecting cables, or replacing or upgrading components). Otherwise, allow 19 inches (48.3
cm) of clearance to remove field-replaceable units.
•
Maintain a minimum clearance of 3 inches on the front and back sides of the chassis for the cooling
air inlet and exhaust ports, respectively. Avoid placing the chassis in an overly congested rack or
directly next to another equipment rack; otherwise, the heated exhaust air from other equipment can
enter the inlet air vents and cause an overtemperature condition inside the router.
Caution
To prevent chassis overheating, never install a Cisco ASR 1002 Router in an enclosed room that is not
properly ventilated or air conditioned.
•
Always install heavier equipment in the lower half of a rack to maintain a low center of gravity to
prevent the rack from falling over.
•
Install and use the cable-management brackets included with the Cisco ASR 1002 Router to keep
cables organized and out of the way of the cards and processors. Ensure that cables from other
equipment already installed in the rack do not impair access to the cards or require you to disconnect
cables unnecessarily to perform equipment maintenance or upgrades.
•
Install rack stabilizers (if available) before you mount the chassis.
•
Provide an adequate chassis ground (earth) connection for your router chassis.
