DIP Function

VLAN、Default、Extend、Reset

VLAN

1-8 ports are isolated from each other, and the PoE Watchdog function is open (hardware takes precedence over software)

Default

All ports can communicate with each other, PoE Watchdog is closed

Extend

7-8 Port: Supports 250m link extension at a rate of 10M, other ports normal, PoE Watchdog open (hardware takes precedence over software)

Reset

Short press restart, long press 5 seconds to restore factory Settings
