Safety Guidelines
Ethernet Connections
There are two 10BaseT/100BaseTX Fast Ethernet ports on the rear panel of the router. Both ports use
unshielded twisted-pair (UTP) cable. We recommend Category 5 UTP cable. The maximum segment
distance is 328 feet (100 meters). UTP cables look like the cables used for ordinary telephones; however,
UTP cables meet certain electrical standards that telephone cables do not. Cables are not included.
WAN Connections
Cisco 7100 series routers support a wide range of WAN ports on the rear panel of the router. For more
information on the cables used with the WAN ports, see Appendix C, “Cable Specifications.”
Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260.
Incorrectly connecting this equipment to a general purpose outlet could be hazardous. The
telecommunications lines must be disconnected 1) before unplugging the main power connector
and/or 2) while the housing is open.
Warning Incorrect connection of this or connected equipment to the general purpose outlet could result in a
hazardous situation.
Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first.
Laser and LED Safety Guidelines
The single-mode transmitter in the ATM port uses a small laser to transmit the light signal to the network
ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode
transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and
avoid staring into open ports or apertures.
The Cisco 7120-SMI and Cisco 7140-MM3 ATM port contains a Class 1 laser warning label.
Warning Class 1 laser product.
Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is
connected, avoid exposure to laser radiation and do not stare into open apertures.
