• If an electrical accident occurs to another person, proceed as follows:
• Use caution; do not become a victim yourself
• Turn off power to the device
• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
and then call for help
• Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate
action
In addition, use the following guidelines when working with any equipment that is disconnected from a power
source but has telephone wiring or other network cabling connections:
• 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
• Remove power cables from all installed power supplies before opening the chassis
Prevent Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic
printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow
these ESD prevention procedures when removing and replacing modules:
• Ensure that the router chassis is electrically connected to the ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an
unpainted surface of the chassis frame 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 chassis.
For the safety of your equipment, periodically check the resistance value of the anti-static strap. It should
be between 1 and 10 megohms (Mohm).
Caution
General Site Requirements
This section describes the requirements your site must meet for the safe installation and operation of your
router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns
or unusually high errors with your existing equipment, the guidelines provided in this section can also help
you isolate the cause of failures and prevent future problems.
