Chapter 2 Installing Cisco Network Modules in Cisco Access Routers Recommended Practices for Cisco Network Modules General Maintenance Guidelines for Cisco Network Modules The following maintenance guidelines apply to Cisco network modules: • Keep the router chassis area clear and dust-free during and after installation. • If you remove the chassis cover for any reason, store it in a safe place. • Do not perform any action that creates a hazard to people or makes equipment unsafe. • Keep walk areas clear to prevent falls or damage to equipment. • Follow installation and maintenance procedures as documented by Cisco Systems, Inc. Safety Warnings for Cisco Network Modules The following safety warning statements apply to all hardware procedures involving Cisco network modules for Cisco access routers. Translations of these warnings are available in the Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information document, which ships with all individual Cisco network module orders, and is also available online. Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12 Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. Statement 194 Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Statement 1030 Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 The following warnings apply in Australia: Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. Statement 4 Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.
