3.2. Electrical Specifications
Power Input
Dual Power Source
The device can be powered from 1 or 2 external power sources:
□
A +12 V DC power source attached to the POWER IN connector and/or ...
□
... through the LAN connector and the network cable from a PoE+ (IEEE 802.3at-2009)
capable network switch.
Having two power sources ensures power supply redundancy:
- If one source fails, the device automatically switches to the remaining source without any
impact on the device operation.
- When power is available at both connectors, the device is powered by POWER IN and it does
not draw any current from the PoE connector.
