Chapter 3 Preparing Your Site for Installation
Electrical Safety
Caution Always tighten the captive installation screws on all the system components when you are installing
them. These screws prevent accidental removal of the module, provide proper grounding for the system,
and help ensure that the bus connectors are properly seated in the backplane.
Electrical Safety
All the system components are hot-swappable. They are designed to be removed and replaced while the
system is operating, without presenting an electrical hazard or damage to the system.
Follow these basic guidelines when you are working with any electrical equipment:
• 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.
• 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, use the following 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 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.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1006
Chassis-Lifting Guidelines
The chassis is not intended to be moved frequently. Before you install the system, ensure that your site
is properly prepared so that you can avoid having to move the chassis later to accommodate power
sources and network connections.
Each time you lift the chassis or any heavy object, follow these guidelines:
• 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 back muscles.
