Uplink port, including 10/100/1000 Mbps self-adaptive Ethernet port and 1000 Mbps
optical port.
DIP switch
● PD Alive (PoE Watchdog): When a terminal device crash is detected, power down
and restart the terminal device.
● Extend Mode: Extends the maximum transmission distance to 250 m, but reduces
average transmission speed to 10 Mbps.
In Extend Mode, the transmission distance of the PoE port is up to 250 m but the
transmission rate drops to 10 Mbps. The actual transmission distance might vary
3
due to power consumption of connected devices or the cable type and status.
● VIP Port: Enable the QoS mode through the DIP switch to achieve priority
transmission of corresponding Ethernet ports.
● Port Isolation: The port isolation mode can be enabled through the DIP switch.
When this function is enabled, the downlink ports are independent, the flow is not
interoperable, and the downlink port and uplink port can communicate with each
other.
Only supported by some models.
