C.4 Powering the PolaRx5e
The receiver can be powered through either:
•
the PWR connector (9-30 VDC)
•
the Ethernet connector (Power over Ethernet - PoE, 37-57 VDC). Please note that only
mode A, as speci
fi
ed in the 802.3af standard, is supported.
•
the internal 6400 mAh, Li-ion battery. When the battery is fully charged, the PolaRx5e
can operate autonomously for up to 24h.
I
f power is provided through both the Ethernet and the PWR connectors, Ethernet power
takes precedence. The current power source (PWR or Ethernet connector), and the voltage
at the PWR connector are reported in the
PowerStatus
SBF bock.
C.4.1 Power Button
I
n case the receiver is powered through the PWR connector or through both PWR and PoE,
pressing the power button turns the receiver o
ff
. Pressing the button again switches the
receiver back on.
I
n case the receiver is
only powered through PoE
, pressing the power button resets the
receiver. After a few seconds, the receiver will restart.
I
n contrast to the PolaRx5, the behavior of the power button of the PolaRx5e remains the
same after a power outage. After a power outage, the receiver will only start up without
pressing the power button in case the battery is fully depleted, just like when the power is
initially applied via the PWR or Ethernet connector.
I
n case the receiver was turned o
ff
before
the power outage, it will remain o
ff
once power is restored.
