3. After you connect the PoE, the system follows the principles listed below to map a
channel.
a) If this is the first time the PoE has been connected, the system can map it to the first
idle channel. After the mapping, the channel can memorize the MAC address of the
IPC. It is a <Channel>---<IPC mac> map. If current channel does not connect to the
other device, system can memorise the current MAC address, otherwise it can
refresh to the newly added device and memorise the <PoE port>---<Channel>.
b) If it is your second time the PoE has been connected, the system can check the
saved MAC address according to <Channel>---<IPC mac> map to make sure current
IPC has connected correctly or not. If system finds the previous information and the
channel is idle, system can map it to the previously used channel. Otherwise system
goes to the next step.
c) Thirdly, according to the <PoE port>---<Channel> map, the system may know the
previous mapping channel of current PoE port. System can select the current
channel if it is free. Otherwise, it goes to the next step:
d) The system goes to find the first idle channel it finds.
Generally speaking, once you connect the PoE, the system will follow the steps listed above to
find the channel available.
System can pop up a dialogue box for you to select a channel to overwrite. The title of the pop-up
interface is the name of the current operational PoE port. In this interface, All PoE channels will
become grey and you will not be able to select them.
