Performance characteristics:
Provide 1 UTP ports, which can be connected to a network card or HUB. (positive and negative line adaptive)
The 10000MAC address LAN table supports transparent transmission of ultra long data frames.
The flow rate is optional. The rate of filtering and forwarding is 15000 frames per second.
Built in power can be supplied with AC 220V or DC -48V, default 220V
-E1/10Base-T front panel
The meaning of the front panel indicator is as follows:
POW---- power indicator, the device lights up after power on.
This light is on when the signal of ALM---- E1 line is lost.
The light flashes when the DATE---- equipment works well.
LINK (netting indicator) - when the wire is inserted, the light is shining, and the lamp flashes when data is transmitted.
This light is on at 10/100M----100M.

Power connection
This device can provide DC -48V or AC 220V power supply mode. It is clear when the order is required.
DC -48V connection mode:
Installation hole -48V protectorate power site installation hole
Note: the protectorate is connected to the power supply separately.
AC 220V connection mode:
The standard 220V connection mode is connected with a random power supply line.
