Electrostatic Discharge Prevention

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that
the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring
that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis
frame to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist
strap and cord must operate properly. If no wrist strap is available, ground yourself by touching the
metal part of the chassis.
Caution
between 1 and 10 megohms (Mohm).

Chassis Lifting Guidelines

A fully configured Cisco 7100 series router weighs approximately 32 pounds (14.5 kg). The chassis
is 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.
Whenever you lift the chassis or any heavy object, follow these guidelines:

using the handles on the port adapters; these types of handles are not designed to support the weight
of the unit. Lift the unit only by grasping the chassis underneath its lower edge.

Always disconnect all external cables before lifting or moving the chassis.
Ensure that your footing is solid, and balance the weight of the object 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.
Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis
