Installation Preparations
4 Close the battery compartment door.
Important: After you install the cable modem and plug it into an AC electrical
outlet as described in Install the Cable Modem (on page 18), it can take as long as
24 hours for the battery to charge fully. However, you can begin using your
high-speed Internet and telephone service immediately after installation. See
Normal Operations (AC Power Applied) (on page 24) for information on how the
LEDs on the front of the cable modem indicate the state of the battery charge.
How Do I Mount the Cable Modem on a Wall? (Optional)
If you wish, you can mount the cable modem to a wall. This section describes how to
mount the cable modem to a wall, and includes a list of equipment you will need
along with suggestions for choosing an appropriate place to mount the cable
modem.
Important: If you have not already done so, insert the battery in the cable modem
before you mount the cable modem on a wall (if desired) or before you install the
cable modem in your home. For assistance inserting the battery in the cable modem,
see Install the Battery (on page 14).
Select an Appropriate Place to Mount the Cable Modem
You may mount the cable modem to a wall that is made of cement, wood, or
drywall. When choosing an appropriate mounting place, refer to the following
recommendations:
Ensure that the mounting location is free of obstructions on all sides, and the
cables should be able to easily reach the cable modem without strain.
Leave sufficient clearance between the bottom of the cable modem and any
flooring or shelving underneath to allow access to cabling.
Allow enough slack in all cables so that the cable modem can be removed for any
required maintenance without disconnecting the cables.
Choose a location that allows adequate ventilation around the cable modem.
Equipment Needed
Verify that you have the following items that you will need to mount the cable
modem:
Two wall anchors for #8 x 1-inch screws
Two #8 x 1-inch pan head sheet metal screws
Drill with a 3/16-in. wood or masonry bit, as appropriate for the wall
composition
