Add maximum device power draw and retain suitable headroom for startup and expansion.
Before you start
Work on a copy or a controlled test when the change can affect production. Keep timestamps, screenshots and the previous configuration so the result can be compared.
Step by step
- List each PoE device with its maximum draw or PoE class.
- Add maximum power values rather than average consumption.
- Add headroom for startup, temperature, replacement, and growth.
- Compare the result with the switch total PoE budget and per-port limits.
- Also verify power-supply redundancy for critical services.
Validation
Repeat the original test after the change and confirm that the expected service works without creating a new regression. Document the final state.
