default OFF. Can support 100m power supply and communication; when dial E is set to ON, the switch
can support 10M/250m long-distance power supply and communication, however, 4 PoE ports are isolated
from each other. There will be no communication between PoE ports.

default OFF. After communication between ports is interrupted, the connection won’t be reestablished
automatically. The user needs to manually enter IP addresses to connect devices again; when dial D is set to
ON, communication can be resumed automatically once the interrupted connection is reestablished.
