Chapter 2 Theory of Operation
The power supply module plugs directly into the optical interface board, no external
cables are required.
A 1.2 GHz GS7000 Node can be configured with one or two power supplies. AC
input voltage can be routed to both power supplies commonly from any node
output port. In addition, AC input voltages can be routed in a split fashion to the
two power supplies. AC input voltages from the left half of the node (output ports 1
– 3) can be routed to power supply 1 independent of AC input voltages from the
right half of the node (output ports 4 – 6) being routed to power supply 2. Each of
the power supplies output voltage rails is diode OR'd within the supply. This creates
common DC powering circuits when multiple supplies are present in the node.
