Power Distribution

A Model GS7000 Optical Hub can be configured with one or two power supplies.
AC input voltage can be routed to both power supplies commonly from either port 3
or port 6 on the housing. In addition, AC input voltages can be routed in a split
fashion to the two power supplies. AC input voltages from port 3 can be routed to
power supply 1 independent of AC input voltages from port 6 being routed to
power supply 2. Each of the power supplies output voltage rails is diode ORed
within the supply. This creates common DC powering circuits when multiple
supplies are present in the node.
