Power supply capacity calculation plan
How to start
First decide how to supply power to the devices:
– Using DCNM‑APS and DCNM‑PS
– Using PoE Ethernet switch
If you want to use PoE Ethernet switches, continue with chapter Calculation using PoE
switches, page 15.

Calculation using DCNM-APS or DCNM-PS
Notice!
If you want to use customized cables, or a more accurate power supply capacity calculation
plan is needed, you should use the power calculation tool.
To calculate the total power supply capacity:
1. Count all multimedia devices.
2. Know the exact location where the devices are installed.
3. Count each system network cable of the same length.
