Guidelines for Rack Installation
• The Cisco ASR 1001-HX Router requires a minimum of 1.75 inches or 4.45 cm rack units of vertical
rack space. The Cisco ASR 1002-HX 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; the heated exhaust air from other equipment can enter the inlet air vents
and cause an overtemperature condition inside the router.
Caution
• 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 1001-HX Router and Cisco
ASR 1002-HX 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.
• Provide an adequate chassis ground (earth) connection for your router chassis.
In addition to the preceding guidelines, review the precautions for avoiding excessive temperature conditions
