AC Power Director:
1.
AC HFC power can be sent to remote locations via the output ports depending on the configuration of the
power port jumpers.
2.
Each RF output port has a plug-in AC Power Director/Jumper.
3.
Check the system maps to determine which power directors should be inserted in a power passing
position. Install each power director as required. Refer to Figure 5.
General Set-up:
1.
Test the optical input power on the system downstream cable with an optical power meter to verify
that it is within the optical input range specification.
2.
Clean the optical connectors on the node and on the service cable then connect them together,
matching the system downstream cable to the node receiver and the system upstream cable to the
laser transmitter.
3.
Verify that the total upstream RF signal level (from all ports) is within the node’s specified input range,
then connect the coaxial cable to the node’s RF In/Out F-port.
4.
The LBON4000 must be grounded, Use a split-bolt grounding stud or your system preferred ground
attachment to ground the Node housing to earth ground. Install the split-bolt grounding stud on the
base housing. Refer to Figure 6.
• For a strand-mounted, install the grounding stud in the threaded hole on the base.
• For a pedestal or surface mounted Node, remove one of the two strand mount brackets,
and install the grounding stud in the threaded hole.
Loosen the top nut and insert the grounding cable. (You may need to remove the nut to insert cable.
With the grounding cable installed, tighten the top nut to secure the cable.
5.
Apply HFC power to the node through power port (40
– 90VAC). Verify that the Return Transmitter
“Normal”
LED and the
“Opt. RX TP”
LEDs illuminate.
