In addition, use the following guidelines when working with any equipment that is disconnected from a
power source but still connected to telephone wiring or network cabling:

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur
when electronic printed circuit cards are improperly handled and can cause complete or intermittent
failures. Always follow ESD-prevention procedures when removing and replacing modules:

Caution
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It
should be between 1 and 10 Mohm.
Lifting Guidelines
A Cisco NAC Appliance CAM/CAS weighs between 15 lb (9.071 kg) and 33 lb (14.96 kg) depending
on what hardware options are installed in the appliance. The appliance is not intended to be moved
frequently. Before you install the appliance, ensure that your site is properly prepared so you can avoid
having to move the appliance later to accommodate power sources and network connections.
Whenever you lift the appliance or any heavy object, follow these guidelines:
OL-20326-01
If an electrical accident occurs, proceed as follows:
Use caution, and do not become a victim yourself.
–
Turn off power to the appliance.
–
If possible, send another person to get medical aid. Otherwise, determine the condition of the
–
victim, and then call for help.
Determine whether the person needs rescue breathing, external cardiac compressions, or other
–
medical attention; then take appropriate action.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for it.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at
the network interface.
Use caution when installing or modifying telephone lines.
When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the component in your
appliance. Just before unwrapping the antistatic packaging, be sure to discharge static electricity
from your body.
When transporting a sensitive component, first place it in an antistatic container or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
Ensure that the Cisco NAC Appliance CAM/CAS is electrically connected to ground.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the appliance to channel unwanted ESD voltages safely to ground. To guard
against ESD damage and shocks, the wrist strap and cord must operate effectively.
If no wrist strap is available, ground yourself by touching a metal part of the appliance.
