Chassis Lifting Guidelines

The Cisco 7500 series chassis are not intended to be moved frequently. Before you install the router,
ensure that your site is properly prepared so you can avoid having to move the chassis later to
accommodate power sources and network connections.
In general, two people are required to lift a Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX,
or Cisco 7576 chassis. (See
hands. To prevent injury, keep your back straight and lift with your legs, not your back.
OL-5008-03 B0
Before beginning any procedures requiring access to the chassis interior, 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 chassis.
Never assume that power has been disconnected from a circuit; always check.
Do not work alone when potentially hazardous conditions exist.
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.
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.
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check.
