Power supply capacity
The total system network cable length and connected devices determine the required power
supply capacity. The power within the DCN multimedia conference system is supplied by:
– The Audio Powering Switch (DCNM‑APS) and the Powering Switch (DCNM‑PS), or
– Off‑the‑shelf PoE Ethernet switches.
Calculation tool
The calculation tool can be used to calculate the total power capacity of the system. This
makes the design and planning of the DCN multimedia conference system easier. The
calculation tool uses the power consumption of devices and the system network cable lengths
to calculate the needed system power supply capacity. The calculation tool is on the DVD
supplied with the DCNM‑APS, and on the Bosch website: www.boschsecurity.com.
