Removing and Installing AC Shunt Power Directors
Removing and Installing AC Shunt Power
Directors
The amplifiers draw AC power from the coaxial cable. This AC power comes from
an external AC power supply.
WARNING:
When AC is applied from RF ports to units downstream, the
downstream equipment shall also be located in a restricted access
location (access restricted to service personnel).
Power can come from the input or output ports, and each amplifier can pass or block
AC power flow on any port without affecting RF continuity. However, at least one
port must pass AC power to bring power into the amplifier.
To set the power direction, install AC shunt power directors for the ports through
To set the power direction, install AC shunt power directors for the ports through
which you wish to pass AC.

Note: A red AC shunt power director is included with the unit. The red shunt is
used to activate the port that supplies power. The red shunt should be removed
before installing or removing the amplifier module from the housing.
CAUTION:
RF connectors and housing seizure assemblies can be damaged if AC
RF connectors and housing seizure assemblies can be damaged if AC
shunt power directors are not removed from the amplifier before
installing or removing the amplifier module from the housing.
To Remove and Insert AC Shunt Power Directors
Complete the following steps to remove and insert AC shunt power directors.
1 Open the node housing. Refer to
1 Open the node housing. Refer to
To Open the Node Housing (on page 15).
2 To remove a power director, pull it straight out from the amplifier module.
3 To insert a power director, refer to the systems design print to determine AC
power routing and install the AC shunt power directors in the required
locations.
