PoE Budget & Switch Margin Analyzer

Part of a Design Flow

This tool starts the Network Design Flow

Use this first to verify switch power headroom before continuing into bandwidth, uplink pressure, and latency checks.

This flow includes both Free and Pro tools. Unlock Pro to complete the full sequence.

Best for: validating switch PoE capacity before installation and preventing overload from IR, heaters, and peak draw conditions.
