Chapter 2 Safety and Compliance
Moving the Chassis
Moving the Chassis
Review the following warnings before attempting installation of the MGX 8260.
Warning Make sure that your rack is bolted to the floor before beginning installation of the MGX 8260 into the rack.
Warning Never attempt to lift a chassis by yourself. The size and weight of a chassis requires two people to lift and move it safely without causing injury or damaging the equipment. Ensure that your footing is solid, and balance the weight of the chassis between your feet. Lift the chassis slowly; never move suddenly or twist your body as you lift. Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles. Always disconnect all external cables before lifting or moving the chassis.
Warning To prevent bodily injury when mounting or servicing this unit in a rack, mount the MGX 8260 at the bottom of the rack if the rack will include only one MGX 8260 node. If mounting the MGX 8260 in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the MGX 8260 in the rack.
Electrical Safety Warnings
Follow these basic guidelines when working with any electrical equipment:
•Disconnect all power and external cables before installing or removing a chassis, or before beginning any procedure that requires access to the chassis interior.
•Do not work alone when potentially hazardous conditions exist.
•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.
In addition, follow these guidelines when working with any equipment that is disconnected from a power source, but is still connected to telephone wiring or other network cabling.
•Never install telephone wiring during a lightning storm.
•Never touch noninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Warning Only a DC power source that complies with the safety extra low voltage (SELV) requirements of UL 1950, CSA C22.2 No.
