5.2 Power Supply of Reader
The reader has two power supply modes, namely, power by power adapter or
power over Ethernet (PoE).
If the network switch is used as PoE switch, the reader will automatically power
on when it is connected to the network. If a standard power adapter is used, the
AC power plug shall be connected to a suitable 100-240VAC, 50-60Hz power
socket.
In both cases, the starting sequence starts from supplying power to the reader. At
this time, the reader is in power-on state, and the “Status” indicator lamp on the
LED panel is always on. 15s later, the indicator lamp flashes regularly. After the
buzzer makes “di-di” sound twice, the system initialization is completed, and the
reader can be operated at this time.
If the reader is being powered through the PoE and the reader detects that
an external power supply has been connected, the reader will restart and switch
to power supply by power adapter. However, if the reader is powered by the
power adapter at the beginning and detects the connection to the PoE network
switch, there is no change and the reader will continue to be powered by the
power adapter. The power adapter has priority over PoE power supply because it
can provide higher power when both power supplies are connected.
