◼ If you want to mount your SBV2402 on a wall, does the location provide a solid surface
for a secure attachment?
For best results when mounting your SBV2402 on drywall, position it so that at least one
of the screws are fastened to a stud. This should prevent your SBV2402 from possibly
pulling out of the wall in the future.
◼ If you want to install your SBV2402 on a desk, is there enough space on either side to
keep the vents clear? Blocking the vents may cause your SBV2402 to overheat.
Connect the SBV2402 to your client device
WARNING
Risk of injury or equipment damage
Connecting your SBV2402 to the home’s existing telephone wiring should only be
performed by a professional installer. Physical connections to the previous telephone
provider must be removed and the wiring must be checked; there must not be any
voltage. Cancellation of telephone service is not adequate. Failure to do so may result in
loss of service and/or permanent damage to your SBV2402.
Before installing your SBV2402:
◼ Check with your service provider (or local cable company) to ensure broadband cable
service is available in your area.
Note: When contacting your service provider, you may need your SBV2402
information listed on the telephony modem label on the bottom of your SBV2402
(see Telephony modem label (page 15).
◼ Check that you have all the items you need to install your SBV2402, see Additional items
needed (not included) (page 10).
◼ Choose a location in your home where your computer and SBV2402 are preferably near
existing cable, phone, and electrical wall outlets.
If a cable outlet is not conveniently located, your service provider can install one.
CAUTION
Risk of equipment damage
Only qualified installation technicians should connect your SBV2402 to house
wiring. Incumbent telephone service must be physically disconnected at the outside
interface box before making any connections.
◼ You have the option to mount your SBV2402 on the wall or place it on a desk, table, or
any other flat surface; see Wall mount the telephony modem (page 19) for more
information.
