MODEL 5345
CABLE MODEM
QUICK START
This Quick Start describes how to connect your Zoom Model 5345 cable modem to a
cable modem service. This lets your cable modem provide Internet access to a computer
or other device connected to the cable modem’s Ethernet LAN Jack. If that device is a
wireless router, wireless devices can connect through the router and Zoom cable modem
to the Internet.

Before installing your cable modem, please read this.
You need to connect the cable modem to a cable modem service that uses any of the
popular DOCSIS standards – 3.0, 2.0, or 1.1. If you need to get cable modem service,
please speak with your cable service provider.
Your cable service provider will need to know your modem's MAC ADDRESS and may
need the account number of your cable service. Your MAC Address is printed on a
label on the bottom of your modem and is called CM MAC. Your account number can
be found on your bill, or you can call your service provider to get your account number.
You need to provide this information when you order cable modem service, or when
calling the cable company after installing your modem, or by filling out the account setup
web page that may appear when you first connect your cable modem to your provider’s
network. You may also be asked for your cable modem's model name and number, which
is ZOOM 5345. If you need the modem's serial number, you can find it near the MAC
address on the label.
If you are replacing an “old” cable modem, do this:
1 Disconnect the coaxial cable from the old cable modem and connect it to your
Zoom modem. If the coaxial cable has a screw-on connector, turn the connector
clockwise when tightening the cable onto the Zoom cable modem.
2 If there’s an Ethernet cable plugged into the old cable modem, unplug the
Ethernet cable from the old cable modem and plug it into the Zoom cable
modem’s LAN (yellow) jack.
3 Connect the Zoom power cube between the Zoom cable modem and a live
power jack. DO NOT use your old cable modem’s power cube on your Zoom
cable modem. If your cable modem’s Power Button is not already pressed in,
press the button in to turn on your cable modem.
4 Go to “Now that your cable modem is connected, do this.” below.
If this is a first-time cable modem installation (that is, you are NOT
replacing an “old” cable modem), do this:
1 Connect a “live” coaxial cable from your cable service provider to your cable
modem First check that the wire in the center of the cable’s connector is
centered, straight, and clean. If the coaxial cable has a screw-on connector, turn
the connector clockwise when tightening the cable onto the Zoom cable modem.
(If you’re not sure a cable is live, you can see whether you get a good TV signal
when that cable is used with a working TV set-top box.) Here are some ways
you can get the live cable:
Coaxial Cable Cable TV Jack
¾ You have a cable TV cable (“coaxial cable”) with a male connector on the end
that isn’t connected to anything. This cable may be coming out of a wall or
connected to a cable TV jack.
¾ There’s a cable TV jack in your wall. You can connect a cable TV “coaxial
cable” between that jack and your cable modem. You may have a coaxial
cable, possibly one that came with a cable modem starter kit from your cable
service provider. If you don’t have a coaxial cable, you can get one at most
electronics stores. You want one with a screw-in male F connector at each
end, with a length that works for your installation.
¾ If you don’t have an available cable TV cable or wall jack, use a coaxial “T
adapter” or “splitter” available from most electronics retailers (see example at
right). Make sure you get one designed for cable modems and/or cable TV.
These typically have one female IN jack and two female OUT jacks. You can
disconnect a live cable from your TV set-top box and screw it into the IN jack of
the splitter. Then connect one coaxial cable from an OUT jack to your TV settop box and another coaxial cable from the other OUT jack to your cable
modem. You can see that this approach uses one splitter and 2 additional
coaxial cables, each of which has male connectors on each end. Some
electronics retailers carry the Zoom Cable Modem Connection Kit which has an
excellent splitter and 2 coaxial cables packaged together at a reasonable price.
You can also purchase splitters and coaxial cable separately if you prefer to do
that, perhaps because you need a special length of coaxial cable.
2 Connect the supplied Ethernet cable between the cable modem’s yellow LA N
jack and a computer’s Ethernet jack. We recommend that you do this even if you
later plan to connect the cable modem to a router.
3 Connect the Zoom power cube between the Zoom cable modem and a live
power jack. If your cable modem’s Power Button is not already pressed in, press
the button in to turn on your cable modem.
4 Go to “Now that your cable modem is connected, do this.” below.
Now that your cable modem is connected, do this.
It normally takes 5 to 30 minutes to establish an Internet link the first time a cable modem
connects to a cable service provider. This allows the cable modem to connect to the
appropriate channels for communication. You’ll see the DS, US, and Online modem lights
on your cable modem flashing until the Online light stays steady green to signal success.
After the cable modem connects to your cable service provider, open your Web browse r
on the computer that’s connected to your cable modem. Then refresh the screen or try to
go to a Web site. Many service providers, including Comcast, typically bring your
browser to a registration page. In that case, follow the instructions on this registration
page to register your modem.
If no web page appears after opening your browser, you need to call your cable company
to register your modem. Below is a list of some major cable service providers’ phone
numbers to call to activate your cable modem. Note that this list is subject to change.
Comcast 1 (855) 652-3446 Time Warner 1 (855) 704 4503
Cox 1 (888) 556-1193 Cable One 1 (877) 692 2253
RCN 1 (866) 832-4726
Once your cable modem is registered either online or through a conversation with
someone at your cable service provider, your service provider will provision your cable
