The copper port is 10/100/1000Base-TX and will auto
negotiate a connection starting at gigabit speed.
High quality Category 5e cable or better should be used.
1000BASE-T requires all four pairs to be present and is far
less tolerant of poorly installed wiring than 100BASE-TX
systems. A 1000Base-SX/LX SFP module socket for Gigabit
optic expansion is located above DIP switch.
This device is plug_and_play; however, the following DIP
switch selections are available.
There are four pins on the DIP switch for port settings as
shown in the table below.

Link-Fault-Pass-Through (DIP Switch 1)
The default setting is link-fault-pass-through OFF. If not
enabled and one side of the link fails, the other side continues
transmitting packets, and waits for a response that never
comes. When ON, LFPT will force the link to shut down as
soon as it notices that the other link has failed. This gives the
application software a chance to react to the situation.
Link Down Alarm (DIP Switch 2 & 3) By default, the link
down alarms are disabled for both copper and fiber.
Duplex Mode (DIP Switch 4) The default setting is auto-
negotiation ON. You may force full duplex mode when set in
OFF position.
