Chapter 8 Cisco ASR 1002 Router Overview and Installation General Rack Installation Guidelines Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071 Warning Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information for Cisco ASR 1000 Series Aggregation Services Routers publication. This document provides important safety information you should know before working with the system. Statement 200 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.
