The items in this image are described by entries in Routed Ethernet, Switched Ethernet, and Other Ports.

Routed Ethernet

Interface Name	Port Name	Port Type
WAN	mvneta2	RJ-45
OPT1	mvneta0	RJ-45

RJ-45 LEDs Configuration

LED Pattern	Description
Left LED only green	Flashes with 1Gb traffic, solid with link.
Both LEDs green	Both flash with 100Mb traffic, solid with link.
Right LED only green	Flashes with 10Mb traffic, solid with link.

Switched Ethernet

Interface Name	Port Name	Port Type
LAN1	mvneta1	RJ-45
LAN2	mvneta1	RJ-45
LAN3	mvneta1	RJ-45
LAN4	mvneta1	RJ-45

The four LAN Ethernet ports are switched ports. By default all of these ports act as a single switch uplinked to the LAN interface on the firewall.

Note

For more details on how the switch operates, see Switch Overview.

For instructions on how to configure the switch see Configuring the Switch Ports.

RJ-45 LEDs Configuration

Both LEDs green	Left Flashes with 1 Gb traffic, solid with link.
Left LED only green	Left flashes with 100 Mb traffic, solid with link.
Right LED only green	Left Flashes with 10 Mb traffic, solid with link.

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

1. Power

   • 12VDC 3.33A with threaded locking connector

   • Power Consumption 5W (idle)

2. Recessed Reset Button (performs a hard reset, immediately turning the system off)

3. USB 3.0 Port

4. Micro SIM

5. Mini-USB Serial Console

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 GUI to avoid data corruption.

USB Ports

USB ports on the device can be used for a variety of purposes.

The primary use for the USB ports is to install or reinstall the operating system on the device. Beyond that, there are numerous USB devices which can expand the base functionality of the hardware, including some supported by add-on packages. For example, UPS/Battery Backups, Cellular modems, GPS units, and storage devices. Though the operating system also supports wired and wireless network devices, these are not ideal and should be avoided.
