Safety Warnings296-1011-202 Rel. 5.0, Doc. Rev. 02.01 viiRegulatory and SafetySafety WarningsGeneral WarningsThe following safety warnings apply:• Mechanical hazards and electrical shock hazards are possible if you remove one or more of the modules. There areno operator-serviceable modules. Only qualified personnel should service this equipment.• This equipment must be connected to a protective ground according to the instructions in this manual. Impropergrounding may result in electrical shock.• This equipment does not provide safety isolation between any port that is connected to a digital networktermination point or any port to which terminal equipment is connected.• The wall circuit breaker provides the main protection for this equipment. For -48 VDC operation, the equipmentmust reside on its own circuit with a breaker rated for 20 A.• Ensure that rack installation does not result in airflow blockage to power supply vents or chassis vents.• Before installing the CVX 600 switch, ensure that the rack is sturdy and well-secured.DC Power Supply WarningsThe DC power supply must be installed in a restricted area, such as an equipment closet or room, in compliance withArticles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70. The DC power source must beisolated from the AC power source and must have a proper ground.The grounded conductor of the DC supply circuit can be connected to the frame grounding conductor of the CVX 600switch. In this case, the following conditions apply:• The CVX 600 switch must be connected to the DC power supply grounded conductor or bonding jumper from thegrounding terminal bar or bus to which the DC power supply grounded conductor is connected.• The CVX 600 switch must be located in the same area as other equipment having a connection between thegrounded conductor of the same DC supply circuit and the grounding conductor, and also the point of grounding ofthe DC system. The DC system must not be grounded elsewhere.• You must not switch or disconnect devices in the grounded conductor between the DC power supply and the pointof connection of the grounding electrode conductor.• A readily accessible disconnect device may be provided in the fixed wiring for a DC power supply. The device mustbe rated for the voltage and current specified.• Before installing equipment in a rack, consider the overall loading of the branch circuit.For safety purposes, the DC power supply requires connection to a grounded outlet. To prevent possible injury fromvoltages on the telecommunications network, disconnect all telecommunications network lines before disconnectingthe DC power supply from the grounded outlet.
