Do not touch the power supply when the power cord is connected. Line voltages are present within
the power supply even when the power switch is off and the power cord is connected.
Use caution when installing or modifying telephone lines to prevent electric shock.
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Do not touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
Hazardous network voltages are present in WAN ports regardless of whether power to the system is

Do not use a telephone to report a gas leak in the vicinity of the leak.
Do not install telephone jacks in wet locations unless the jack is specifically designed for wet

Fiber-optic ports (for example, FDDI, OC-3, OC-12, OC-48, ATM, GBIC, and 100BaseFX) are
considered Class 1 laser or Class 1 LED ports.
These products have been tested and found to comply with Class 1 limits of IEC 60825-1, IEC
60825-2, EN 60825-1, EN 60825-2, and 21CFR1040.
To avoid exposure to radiation, do not stare into the aperture of a fiber-optic port. Invisible radiation
might be emitted from the aperture of the port when no fiber cable is connected.
