Cisco Model GS7000 4-Port Node 1 GHz with 42 54 Split Installation Guide
Power Supply Module

The power supply module plugs directly into the optical interface board, no external
cables are required.
A 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.
