Power Requirements
A Cresnet network system must be designed to handle the total power that will be required by
all Cresnet clients on the network. Power requirements vary based on the number of Cresnet
clients in a system, the power draw for each Cresnet client, wire run lengths from a power
source, and the wire gauge used. Insufficient power is a common cause of Cresnet network
issues, so it is important to ensure your network design addresses all power requirements.
The following sections explain how to calculate and troubleshoot power requirements for your
Cresnet network system.
Cresnet Power Calculator
The Cresnet Power Calculator is a tool that allows integrators to easily calculate the total power
draw for all Cresnet clients connected to a given leg of the Cresnet network. The Cresnet Power
Calculator also calculates the total power available from Cresnet servers and power supplies,
allowing integrators to determine whether the provided device combination will result in a power
surplus or deficit.
