Power Distribution
Introduction
The 1.2 GHz GS7000 Node is powered by one or two power supplies.
Power Distribution
1.2 GHz GS7000 Node power distribution functions are described below.
Stage
Description
1
45 to 90 V AC is applied to one or two power supply modules in the 1.2 GHz
GS7000 Node.
2
The power supply module(s) convert(s) the AC input to +24.5, +8.5, -6.0, and
+5.5 V DC.
3
The +24.5, +8.5, -6.0, and +5.5 V DC lines are routed to 1.2 GHz GS7000 Node
internal modules.
4
If two power supplies are installed and both are active, the load is shared
equally between them.
5
An AC segmentable shunt is available to separate the AC connection to ports
1-3 from that of ports 4-6. This allows the node to be configured where one
power supply is powered from ports 1-3 and a second power supply is powered
from ports 4-6.
