Power Supply
Two pin terminal connector with 3.5 mm pitch is used to power the router. Corresponding
connector is supplied with the router as a standard accessories.
Pin
Signal mark
Description
1
VCC(+)
Positive pole of DC supply voltage (+9 to +48 V DC)
2
GND(-)
Negative pole of DC supply voltage
Table 7: Power connector pinout
Figure 16: 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 router is grounded, using the grounding screw, there is no protection against the
reversed polarity. The negative pole of the DC power supply must be at the same voltage
reference as the grounding screw. If not, a voltage difference between these two points
might damage the router, and only an authorized service center can fix it.
The power voltage for the PoE router version must be 48 V DC to work as the PoE PSE
device.
