Node Power Limitations
Nodes and hub nodes must be configured in a manner that prevents potential
thermal overloads. Heat generated by the node can reduce the life of the equipment.
CAUTION:
The life of the equipment may be reduced if configured to draw more than the
recommended level of power from the power supplies.
Two power supplies can provide a maximum power level of 150 watts to the node or
hub node. The RF amplifier uses the majority of the available power. Maintain the
total power consumption of all modules in the housing within these guidelines to
minimize the heat generated. Find the optimal configuration by summing the power
consumption of the RF amplifier plus the other individual modules in the housing
using the following table.
Important: Do not populate the housing with any combination of modules that
would draw more than the available power of 150 watts.
The following table lists the modules and their respective power consumption.
