Cabling and Startup for a Single User
Allow 5 to 30 minutes to power up the first time because the SURFboard cable modem
must find and lock on the appropriate channels for communications.
1
Be sure your computer is on and the cable modem is unplugged.
2
Connect one end of the coaxial cable to the cable outlet or splitter. Connect the
other end of the coaxial cable to the CABLE connector on the cable modem.
Hand-tighten the connectors to avoid damaging them.
3
Insert the SURFboard Cable Modem CD-ROM into your CD-ROM drive.
4
Plug the power cord into the
POWER
connector on the cable modem and the
electrical outlet. This turns your SURFboard cable modem on. You do not need to
unplug it when not in use.
5
Check that the lights on the front of the cable modem cycle through this sequence:
■
Power flashes during the self-test and changes to solid green when the self-test
is successfully complete.
■
Receive flashes while scanning for the receive channel and changes to solid
green when the receive channel is locked.
■
Send flashes while scanning for the send channel and changes to solid green
when the send channel is locked.
■
Online flashes while the cable modem downloads configuration data and
changes to solid green when the download is complete.
