Installation Safety, ESD Precautions, and Required Tools Safety Guidelines Observe the following guidelines to ensure your safety and protect the equipment. This list does not identify all of the potentially hazardous situations that you may encounter in the workplace, so be alert and exercise care when working with any of the switch router s electrical or electronic components. Always disconnect all power cords and line card interface cables before moving the Cisco 12008. Keep tools and switch router components away from walkway areas. Do not work alone if potentially hazardous conditions exist in the work area. Do not take any action that poses a potential hazard to yourself, other personnel, or the equipment. Carefully examine your work area for potential hazards, such as damp floors, ungrounded power extension cables, and missing safety grounds. Safety with Electricity Observe the following basic safety guidelines when working with the switch router s electrical and electronic equipment: Before beginning any procedure requiring access to the card cages or other interior switch router components, locate the emergency power-off switch for the room in which you will be working. Do not work alone if potentially hazardous conditions exist in your work area. Never assume that power has been disconnected from a circuit; always verify that power has been removed before working on the switch router. Do not perform any action that poses a potential hazard to yourself, other personnel, or the equipment. Carefully examine your work area for possible hazards, such as damp floors, ungrounded power extension cables, and missing safety grounds. In addition, observe the following guidelines when you are working with equipment connected to telephone wiring or other network cabling. Warning Do not work on the system or connect or disconnect cables during lightning storms. Never install telephone jacks in wet or damp locations unless the jack is specifically designed for use in such areas. Never touch uninsulated telephone wires or terminals unless telephone lines are disconnected at the network interface. Use caution when installing or modifying telephone lines. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage to circuit boards can occur if they are handled improperly. Such mishandling can result in intermittent or complete failures of the board. When handling circuit boards, observe the following guidelines to prevent ESD damage: Always use an ESD-preventive wrist strap and ensure that the strap makes adequate contact with your skin. 2 Cisco 12008 Gigabit Switch Router Cable-Management System Replacement Instructions
Tools and Parts Required When removing or installing any switch router circuit board or assembly, insert the equipment end of the wrist strap (the banana jack) into the ESD socket on the lower left edge of the upper card cage. If you intend to return a faulty circuit board to the factory for repair or replacement, immediately place the board in an antistatic bag to prevent ESD damage to the board. The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing can still cause damage to electronic components. Caution For safety, periodically check the resistance value of the antistatic wrist strap. The resistance measurement should be between 1 and 10 megohms. Tools and Parts Required You will need the following tools to install or replace a cable-management tray or a cable-management bracket: 1/4-inch flat-blade screwdriver Number 1 Phillips screwdriver ESD-preventive wrist strap ACS-GSR8-CCBLM(=) Cable-management tray ACS-GSR-LCCBLM(=) Cable-management bracket Replacing the Cable-Management System This section presents the procedures for removing and installing a cable-management tray or a cable-management bracket for the Cisco 12008.
