Applying Power to the Hub

Overview

The Model GS7000 Optical Hub requires input power of 45 to 90 VAC from and
external power source. This power is supplied through the RF cables connected to
port 3 and/or port 6 on the housing. The incoming AC power is feed to one or two
power supply modules which in turn supply four well-regulated DC output
voltages to the hub's internal modules, as shown in the following illustration. Refer
to Power Supply Module (on page 80) for a complete description of the power
supplies.
The powering configuration is flexible and can be changed to meet most network
requirements. Power direction is configured by installing AC shunts for the ports
through which you want to pass AC power. An AC segmentable shunt is provided
to configure power direction between the two sides of the node.

Hub Powering Procedure

Follow these steps to apply power.
1 Determine which of the RF cables, connected to port 3 or port 6 or both, will
carry the 45 to 90 VAC input power.
2 Install shunts in the locations that correspond to the AC-powered RF ports.
Each port's shunt is located on the RF amplifier module near the port as shown
in the following illustration.
