Failover power support (NWL-12-01 only)
The NWL-12 Series Router includes support for connection of two power sources at the same time. When a PoE Ethernet cable is
connected and DC power is also supplied to the DC input jack of the router, the router will source power exclusively from the PoE
source. In the event that power from the PoE cable is lost, the router will automatically switch to source power from the DC input
jack, without affecting the router’s operation. When PoE power is restored, the router automatically switches back to receive power
from the PoE input source.
Viewing power source information
You can view the current power input mode in the Advanced status section of the device’s web user interface. This is useful for
remotely monitoring the device. You can also use the Software Development Kit to access this information for advanced purposes
(e.g. configuring SMS alerts to inform you of the power status of the router).
To view the router’s power source information, log in to the router and expand the Advanced status box on the status page. See
the
Status section of this manual for more information on the status page.
Power consumption
To assist with power consumption planning, the following table summarises average power consumption during the various states
of the NWL-12 Series Router under normal usage conditions. It’s important to note that this table serves as an indication only as the
power consumed by the device is affected by many variables including signal strength, network type, and network activity.
