•Leave enough space at the rear of the cable access router to allow sufficient space for the connected
cables without crimping.
Powering the Computer ON
Step 1 Power ON your computer and wait until it boots to the Windows desktop.
Connecting Power to the Cisco uBR925 Router
This procedure connects the Cisco uBR925 Cable Access Router to its power supply and to the
grounded wall outlet supplying power to the unit. The cable access router is meant to be left on at all
times, and therefore, has no power switch.
Note Always use the power supply unit that is supplied with the Cisco uBR925 Cable
Access Router.
Step 1 Connect the eight-pin connector on the power supply cable into the socket labeled “Power”
on the rear panel of Cisco uBR925 Cable Access Router. Push the plug into the connector
until it locks securely.
Step 2 Connect the plug end of the power cord into the other end of the power supply.
Step 3 Plug the prong end of the power cord into a grounded electrical wall outlet. Power is
immediately supplied to the cable access router.
Warning
Never defeat the ground conductor or operate the equipment in the absence of a
suitablyinstalledgroundconductor.Contacttheappropriateelectricalinspectionauthority
or an electrician if you are uncertain that suitable grounding is available.

Step 4 Verify that the OK LED on the front panel of the Cisco uBR925 Cable Access Router starts
blinking a few moments after power is applied. If this LED does not light or blink, check that
the power supply cable is plugged into the cable access router and into a working wall outlet.
Tip After a few moments, the OK LED should stop blinking and come on solid, indicating
that the router has loaded the Cisco IOS software and is ready for operations with the cable
network.
Connecting the Cisco uBR925 Cable Access Router to the
Cable System
This procedure connects the Cisco uBR925 Cable Access Router to the cable network. This is required
for all installations.
Step 1 If you are using the same outlet for both cable TV and cable network service, install a cable
splitter/directional coupler to provide separate signals for the TV and cable network signals.
(Contact your service provider for details on how to properly connect a cable splitter or
directional coupler.)
Step 2 Plug one end of the coaxial cable into the cable TV wall outlet.
Step 3 Connect the other end of the coaxial cable to the connector on the rear panel of the
Cisco uBR925 Cable Access Router that is labeled Cable TV In.
Step 4 Hand-tighten each connector, making sure that each is finger-tight.
Step 5 The CATV Link LED should turn on solid after connecting the Cisco uBR925 Cable Access
Router to the cable TV wall outlet. If the CATV Link LED does not come on solid within a
few minutes, check that the coaxial cable is properly plugged into the correct cable TV outlet
and in to the cable access router’s Cable TV In connector.
Connecting to Telephones, Modems, or Fax Devices (optional)
If you have purchased voice services from your service provider, use the following procedure to
connect the Cisco uBR925 Cable Access Router to telephone, modem, or fax devices. If you have not
purchased voice services, skip to the “Connecting to the Computer (Ethernet, optional)” section on
page 8.

Step 1 Obtain the telephone number assignments for each voice port from your service provider, and
label each telephone, modem, or fax device with its assigned number.
Step 2 Connect the RJ-11 end of this cable to the appropriate voice port (labeled “V1+V2” or “V2”)
on the rear panel of the Cisco uBR925 Cable Access Router. Press the cable firmly into the
receptacle.
Step 3 Connect the other end of the cable to the telephone, modem, or fax device that has been given
the number assigned for that voice port. Press the cable firmly into the receptacle.
Step 4 Repeat Steps 2 and 3 to connect a second telephone, modem, or fax device to the other voice
port.
Note The V1+V2 connector supports either a single-line or a two-line analog telephone that
uses a four-wire connection. If using a two-line telephone, the second line behaves as if it
were a single-line telephone plugged into the V2 voice port; you can then plug a second
device in to the V2 port and use it as an extension to the second line telephone.
Caution Do not plug the Cisco uBR925 Cable Access Router into any RJ-11 jack in your
home, unless otherwise instructed by your service provider. The cable access router must not
be plugged in to the Public Telephone Switched Network (PTSN) or in to any jack that is
connected to the PTSN—doing so will damage the cable access router.
Connecting to the Computer (Ethernet, optional)
These steps connect the Ethernet port on the Cisco uBR925 Cable Access Router to a computer using
an Ethernet network adapter card. This is required only when you are using the Ethernet port to
connect the cable access router to a computer; if you are using the USB port, see the next section.
Note Do not proceed with these steps if your computer does not have a working Ethernet
interface. If necessary, install an Ethernet network adapter card according to the
manufacturer’s instructions before proceeding.
Step 1 Plug one end of the supplied straight-through Ethernet cable to any of the four RJ-45
connectors labeled Ethernet on the rear panel of the Cisco uBR925 Cable Access Router.
Step 2 Plug the other end of the Ethernet cable into the RJ-45 connector on your computer’s Ethernet
network adapter.
Step 3 Verify that the appropriate Ethernet Link LED (numbered 1 to 4) on the front panel of the
Cisco uBR925 Cable Access Router is on. If this LED does not come on, check that the
Ethernet cable is plugged into the correct RJ-45 connector on your computer and that the

9
computer is turned on. Also verify that the other end of the cable is plugged into the correct
Ethernet connector on the Cisco uBR925 Cable Access Router. Finally, verify that the
Ethernet cable is a straight-through cable and not a crossover cable.
If the steps above do not correct the problem, check that the Ethernet adapter is configured for TCP/IP
operation, as described in the “Configuring the Computer for Ethernet Network Access” section on
page 17.
Connecting to the Computer (USB, optional)
These steps connect the Cisco uBR925 Cable Access Router to a computer using the USB port. This is
required only when you are making a USB connection to a computer; if you are using an Ethernet port,
see the previous section.
Step 1 Before making any connection, verify the following requirements for a USB connection:
– The computer is running Windows 98, Windows 98 Second Edition, Windows Millennium,
or Windows 2000. Windows 95 and Windows NT do not support USB networking
connections.
– Both the Cisco uBR925 Cable Access Router and the computer must be powered on.
– If using a USB hub, verify that it is already installed and working before connecting the
Cisco uBR925 Cable Access Router. (A USB hub allows multiple devices to be connected to
one PC, but it does not allow multiple computers to be connected to the Cisco uBR925 Cable
Access Router.)
Step 2 Plug the broad, flat plug (the type “A” or host-end, shown in the figure on the next page) of
the USB cable into the USB port on your computer (or USB hub).
Step 3 Plug the other, rectangular end of the USB cable (the type “B” or device-end, shown in
Figure 3) into the USB port on the rear panel of the Cisco uBR925 Cable Access Router.
