Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001 Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 General Safety Practices Follow these guidelines to ensure personal safety and protect the equipment: Warning • Keep the chassis area clear and dust-free during and after installation. • Put the removed chassis cover in a safe place. • Keep tools away from walk areas where you and others could fall over them. • Do not wear loose clothing that could get caught in the chassis. • Wear safety glasses if you are working under any conditions that might be hazardous to your eyes. This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both. Statement 1043 Safety Tips Use these tips as safety guidelines when installing or working around this equipment. • Locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power. • Disconnect all power before installing or removing a chassis. • Do not work alone if potentially hazardous conditions exist. • Never assume that power is disconnected from a circuit. Always check. Cisco VG224 Voice Gateway Hardware Installation Guide 3-2 OL-5006-04 Chapter 3 Installing the Cisco VG224 Voice Gateway Site Log • Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds. • If an electrical accident occurs, proceed as follows: – Use caution; do not become a victim yourself. – Turn off power to the system. – 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. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic components are improperly handled; it can result in complete or intermittent failures. Always follow ESD-prevention procedures when removing and replacing components. Caution • Ensure that the chassis is electrically connected to earth ground. • Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. • Connect the clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis) or to an unpainted chassis frame surface. For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm). Site Log We recommend that you maintain a Site Log to record all actions relevant to the system.
