• 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.
Always follow these electrostatic discharge (ESD) prevention procedures when removing and replacing
modules:
• Ensure that the router chassis 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 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
Site Requirements
Follow the general precautions listed below when installing or working with your device:
• Do not block cooling vents.
• Route system cables, and the power supply cable and plug so that they cannot be stepped on or tripped
over. Be sure that nothing else rests on your system component cables or power cable.
• If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component
damage.
