3 CONNECTIONS
3.1 Ethernet LAN 1A – D
The Ethernet interfaces LAN 1A – D offer each a green LED. It is on when there is a LAN
link established and blinks when there is traffic. The yellow LED is not connected.
The Ethernet interfaces LAN 1A – D are equal. They are connected over an integrated 4-port
switch.
The Ethernet interfaces LAN 1A – D support Auto MDI/MDIX.

CAUTION!
Providing the Remote Access Gateway IGW/925-W with a higher voltage than the regular
11 .. 28 VDC ±10 % could cause damaged board components!
CAUTION!
Do NOT turn on the power supply while connecting the power adapter cable with the
Remote Access Gateway IGW/925-W. This could cause damaged board components! First
connect the power adapter cable and THEN turn the power supply on.
