Installing the Surge-Gap Drop Amplifier
General Installation Notes
Keep the following in mind when installing the drop amplifier.
•The drop amplifier has no power switch. Power is on when the AC adapter is
plugged into an outlet and the power cable is connected to the drop amplifier.
•The power “on” state is indicated by the LED lighting.
•Terminate any unused RF ports by attaching 75 ohm terminators (provided).
•A standard length of RG6 coaxial cable is required for installation (3-feet
provided).
Parts Included in the Kit
The following table shows the contents of the kit.
Part Illustration Function
Surge-Gap Drop
Amplifier
A: Power Port – for powering by a
coaxial cable connected to the AC
adapter.
B: Input Cable Port
C: Power Inserter/ Output Port
(Labeled “In PWR + Out RF”)
D: Output Port Only
AC Adapter
The AC adapter is connected to the
drop amplifier at port A by the
coaxial cable (provided). The AC
adapter is then plugged into an AC
outlet.
Power Inserter
The power inserter is used with
outdoor installations.
75 ohm Terminators
Terminators must be installed on
any unused output ports to reduce
noise getting into the cable network.

3-foot Coaxial Cable The coaxial cable connects the AC adapter to the drop amplifier.
Installation Screws (2) The screws are used to attach the drop amplifier to the wall.
Indoor Installation
Follow the steps below to install the drop amplifier inside the home.
Note: The power inserter is not used for indoor installations.
CAUTION:
Avoid possible shorting of the AC adapter. Make all connections to the drop
amplifier before the AC adapter is plugged into an electrical source.
1. Locate the drop amplifier near the drop cable and a 120 V AC or 240 V AC
outlet. Look for the areas where the cable enters the home or is split for
devices. This is typically in the basement or the attic. You may also find a
termination within a network interface box (gray box) on the outside of your
home.
2. Mount the drop amplifier to a stud or wall using the installation screws.
3. Make all connections to the drop amplifier as shown in the diagram below.
4. Plug the AC adapter into the AC outlet.

Follow the steps below to install the drop amplifier outside the home.
Note: Outdoor installations require the optional power inserter and water sealing F-
connector boots or shrink tubing (not provided).
CAUTION:
Avoid possible shorting of the AC adapter. Make all connections to the drop
amplifier before the AC adapter is plugged into an AC outlet.
1. Locate the drop amplifier near the drop cable.
Note: Cisco recommends that you install the drop amplifier inside a network
interface box. However, you can install the drop amplifier in an exposed area
if necessary.
2. Mount the drop amplifier to a stud or wall using the installation screws.
3. Connect the power inserter to the customer equipment drop, locating it near
an AC outlet.
4. Attach the power inserter to the AC adapter exactly as shown in step 5.
WARNING:
Avoid possible electrical shock and damage to customer equipment.
Make sure the power inserter is oriented as shown in the diagram in step
5.
5. Place water sealing F-connector boots or shrink tubing (not provided) on the
cable connections of the drop amplifier as shown in the diagram below.
