Node Power Limitations - Cisco GS7000 Installation And Operation Manual

Theory of Operation
• +24.5 VDC @ 6.2 Amps
• +8.5 VDC @ 1.0 Amps
• +5.5 VDC @ 1.3 Amps
• -6.0 VDC @ 0.8 Amps
Test points are provided on top of the power supply module for AC input and all output DC voltage rails.
The power supply module plugs directly into the optical interface board, no external cables are required.
A 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.

Node Power Limitations

The node must be configured in a manner that prevents potential thermal overloads. Heat generated by the
node can reduce the life of the equipment.
