Connecting the Router to Your Local Network
Connecting the Router to Your Local Network
The router is connected to your local Ethernet network through the yellow 10/100
Ethernet port. You must provide the following items for this connection:
• A straight-through, RJ-45-to-RJ-45 Ethernet cable
• A 10/100-Mbps Ethernet hub or switch
Warning The ports labeled 10/100-Mbps Ethernet port and Console port are safety
extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits. Because BRI circuits are treated like telephone-network
voltage, avoid connecting the SELV circuits to the telephone network voltage
(TNV) circuits. (To see translated versions of this warning, refer to the
Regulatory Compliance and Safety Information for Cisco 1700 Routers document
that came with the router.)
Caution Always connect the Ethernet cable to the yellow ports on the router. Do not
connect the cable to an ISDN S/T or U port on a WIC or to an NT1 that is
connected to a WIC. Accidently connecting the cable to the wrong port can
damage your router.
Follow these steps to connect the router to your local network:
Step 1 Connect one end of the cable to the yellow Ethernet port (labeled 10/100-Mbps
Ethernet port).
Step 2 Connect the other end of the cable to a network port on the hub or switch.
