Description
1
VCC(+)
Positive pole of DC supply voltage (+9 to +48 V DC)
2
GND(-)
Negative pole of DC supply voltage

Figure 8: Power Connector Pinout
Required power supply voltage for the router is b9 V and +48 V DC, see the
connection scheme on Figure
. Protection against reversed polarity without signaling is built
into the router. For correct operation it is necessary that the power source is able to supply
power of 18 W (non-PoE version).
If the negative pole of the router is grounded, there is no protection against reversed
polarity! The only protection left is the fuse inside the device. Only the service center can
restore the router’s functionality.
The power voltage for the PoE router version must be 48 V DC to work as the PoE PSE
device.
In applications requiring low power consumption (such as solar power - not 7/24 mode)
is strictly recommended to use the Low Power Mode (LPM) mode prior to powering down
the entire router.
