Note

Prior to pfSense® software version 2.4.3, the switched Ethernet ports on the SG-3100 did not support auto MDI-X and required crossover cable unless the client-side connection supported auto MDI-X. This was resolved with 2.4.3 and later versions and a crossover cable is no longer required.

Warning

The LAN ports do not support the Spanning Tree Protocol (STP). Two or more ports connected to another Layer 2 switch, or connected to 2 or more different interconnected switches, could create a flooding loop between the switches. This can cause the router to stop functioning until the loop is resolved.

Other Ports¶

Power (12 VDC with threaded locking connector)
Recessed Reset Button (performs a hard reset, immediately turning the system off)
USB 3.0
Micro SIM
Console (Mini-USB)

Warning

A hard reset of the system could cause data corruption and should be avoided. Halt or reboot the system through the console menu or the web configurator to avoid data corruption.
