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 RF MAC. Your service provider
may refer to this as a CM MAC address or as a Cable Modem MAC address. Your
account number can be found on your bill, or you can call your service provider and ask
them for you 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 appears 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 5341J. If you need the modem's serial
number, you can find it near the MAC address on the label.
