Installation Preparations
Mounting the Cable Modem on a Wall
1 Using a drill with a 3/16-inch bit, drill two holes at the same height and 3 inches
apart.
Note: The preceding graphic illustrates the location of the mounting holes on the
back of the cable modem.
2 Are you mounting the cable modem into a drywall or concrete surface where a
wooden stud is available?
If yes, go to Step 3.
If no, drive the anchor bolts into the wall, and install the mounting screws
into the anchor bolts; leave a gap of about 1/4-inch between the screw head
and the wall. Then, go to Step 4.
3 Install the mounting screws into the wall; leave a gap of about 1/4-inch between
the screw head and the wall. Then, go to Step 4.
4 Verify that no cables or wires are connected to the cable modem.
5 Lift the cable modem into position. Slip the large end of both mounting slots
(located in the side of the cable modem) over the mounting screws, and then
slide the cable modem down until the narrow end of the keyhole slot contacts the
screw shaft.
Important: Verify that the mounting screws securely support the cable modem
before you release the unit.
