Removing and Installing AC Shunt Power Directors
Removing and Installing AC Shunt Power
Directors
The amplifiers module 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 module 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 shunt
RF connectors and housing seizure assemblies can be damaged if AC shunt
power directors are not removed from the amplifier module 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 17).
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
