Chapter 2 Preparing for Installation
Safety Recommendations
•
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.
Warning
See the installation instructions before you connect the system to its power source.
Warning
Before working on a chassis or working near power supplies, unplug the power cord on AC units or
disconnect the power at the circuit breaker on DC units.
Warning
Do not touch the power supply when the power cord is connected. For systems with a power switch,
line voltages are present within the power supply even when the power switch is off and the power
cord is connected. For systems without a power switch, line voltages are present within the power
supply when the power cord is connected.
•
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.
In addition, use the guidelines that follow when working with any equipment that is disconnected from
a power source, but still connected to telephone or network wiring:
•
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.
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
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
Figure 2-1
.) Grasp the chassis underneath the lower edge and lift with both
hands. To prevent injury, keep your back straight and lift with your legs, not your back.
