Chapter 
  •
If an electrical accident occurs, proceed as follows:
  –
Use caution; do not become a victim yourself.
  –
Disconnect power from the system.
  –
If possible, send another person to get medical aid. Otherwise, assess the condition of the 
victim, and then call for help.
  –
Determine whether or not the person needs rescue breathing or external cardiac compressions; 
then take appropriate action. 
  •
Use the Cisco 170 series appliance within its marked electrical ratings and product usage 
instructions.
  •
Install the Cisco 170 series appliance in compliance with local and national electrical codes as listed 
in the Safety and Compliance Guide for the Cisco Content Security Appliances document.
  •
The Cisco 170 series appliance is equipped with AC-input power supplies and is shipped with a 
3-wire electrical cord with a grounding-type plug that fits into a grounding-type power outlet only. 
Do not circumvent this safety feature. Equipment grounding should comply with local and national 
electrical codes.
Preventing Electrostatic Discharge Damage
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 removing and replacing components. Ensure that 
the appliance is electrically connected to an 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 
appliance frame to safely ground ESD voltages. To properly guard against ESD damage and shocks, 
the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by 
touching the metal part of the appliance.
  •
For safety, periodically check the resistance value of the antistatic strap, which should be between 
1 and 10 megohms (Mohms).
Working in an ESD Environment
  •
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 appliance 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 appliance 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 appliance.
