2 ALARM A ALARM B EJECT EJECT LINK COLL MII LINK RJ-45 COLL MII RJ-45 Chassis Front Covers Overview Chassis Front Covers Overview Cisco, Cisco 4, and Cisco 8 Routers are equipped with front covers, or bezels, over the blower module, the line card and route processor (RP) card cage, and the switch fabric and alarm card cage. (See Figure.) The front covers protect cables from being disconnected or damaged by accidental contact and present a consistent product appearance. As shown in Figure, the front covers over the blower module and over the line card and RP card cage use snap-on fasteners. The front cover over the switch fabric and alarm card cage is fastened to the air filter door with standard screws. Note Recently released routers have bezel extenders installed on the front cover (bezel) for the line card and route processor (RP) card cage to bring the cover out an additional inches (5.8 mm) to allow more room for cables. If your chassis does not have these extenders and you want to purchase them, contact Cisco sales. (See the Installing the Bezel Extenders on the Front Cover section on page if you are self-installing the bezel extenders.)

3 Bezel Extenders Overview Bezel Extenders Overview Recent releases of the Cisco, Cisco 4, and Cisco 8 Router include a pair of bezel extenders on the front cover for the line card and RP card cage. (See Figure.) These bezel extenders (Figure, items 4 and 5) provide an additional inches (5.8 mm) between the inside of the bezel and the front of the chassis to prevent the possibility of compromising the bend radius of your cables. If you have obtained the optional bezel extenders separately from the router, review this section and the Installing the Bezel Extenders on the Front Cover section on page. Note The bezel extenders are designed for installation on the line card and RP card cage bezel only.

5 Preparing for Installation Safety Guidelines Safety with Equipment Safety with Electricity Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. In addition, review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco Series Router publication that accompanied your router before installing, configuring, or maintaining the router. The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert. Always disconnect all power cords and interface cables before moving the system. Never assume that power is disconnected from a circuit; always check. Keep tools and assembly components away from walk areas. Do not work alone if potentially hazardous conditions exist. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds. Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working. Disconnect all power and external cables before installing or removing a router. Never assume that power has been disconnected from a circuit; always check. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Never install equipment that appears damaged. Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds. If an electrical accident does occur, proceed as follows: Use caution; do not become a victim yourself. Disconnect power to the router. If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help. Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action. In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring: Never install telephone wiring during a lightning storm. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Use caution when installing or modifying telephone lines. 5

6 Preparing for Installation Preventing Electrostatic Discharge Damage Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as V, while static voltages as high as 5,V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines: Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact. Caution You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between and megohms. When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 4.) Avoid contact between the component and your clothing. The ESD-preventive wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage. Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag. When installing a line card or route processor (RP), use the ejector levers to seat the card connectors in the backplane, then tighten both captive screws on the faceplate of the card. These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the card connector is seated in the backplane. When removing line cards, clock and scheduler cards, switch fabric cards, or an RP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot. Handle line cards, clock and scheduler cards, switch fabric cards, or an RP by the metal card carrier edges only; avoid touching the board or any connector pins. 6
