Installing the Surge-Gap DropAmplifier
General Installation Notes
The installer should review EN 50083-1/A1:1997 and install this product per EN
50083-1/A1:1997. 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.
•Terminate any unused RF ports by attaching 75 ohm terminators.
Local Powering
Follow the steps below to install the drop amplifier inside the customer premises.
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.
2. •Connect the drop amplifier as shown in the following diagram.
•Plug the AC adapter into the AC outlet.

Remote Powering
Follow the steps below to install the drop amplifier outside the customer premises.
Note: Outdoor installations require the optional power inserter and water sealing F-
connector boots or shrink tubing.
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.
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. Connect the power inserter to the customer equipment drop, locating it near
an AC outlet.
3. Attach the power inserter to the AC adapter, as shown in the diagram in step
4.
WARNING:
Avoid possible electrical shock and damage to customer equipment.
Make sure the power inserter is oriented as shown in the diagram in step
