Warnings and Cautions Chapter 2 Preparing for Installation • When installing an uplink or access card, confirm that the card is fully seated in the midplane and tighten the spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the system, and help ensure that the connectors are seated in the midplane. See the "Removing and Installing an Uplink Card" section on page 5-49 and "Removing and Installing an Access Card" section on page 5-58. • When removing an uplink or access card, use the spring-loaded screws to unseat the card connector from the midplane. See the "Removing and Installing an Uplink Card" section on page 5-49 and "Removing and Installing an Access Card" section on page 5-58. • Handle cards by the spring-loaded screws only; avoid touching the board or connector pins. • Place a removed card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag. • Avoid contact between the card and clothing. The wrist strap protects the board only from ESD voltages on the body; ESD voltages on clothing can still cause damage. Laser Safety The uplink card is equipped with a Class 1 laser that emits invisible radiation. Do not stare into open line card ports. The following laser warnings apply to the Cisco 10720 Internet Router: Class 1 Laser Product Warning Warning Class 1 laser product. Statement 1008 General Laser Warning Warning Avoid exposure to laser radiation. Do not stare into an open aperture, because invisible laser radiation may be emitted from the aperture when a cable is not inserted in the port. Statement 125 For translated Class 1 laser warnings, refer to the Regulatory Compliance and Safety Information for the Cisco 10720 Internet Router publication. Class 1 LED Product Warning Warning Class 1 LED product. Statement 1027 Cisco 10720 Internet Router Installation and Configuration Guide 2-4 78-13062-10
