Perform the following steps based on the desired connectivity.
Ethernet/PoE
If you are using a wired Ethernet connection, connect the Ethernet cable to the 0PoE port on the router. To use power over Ethernet (PoE), connect the cable's other end to a PoE-enabled network source or an IEEE 802.3af compatible PoE injector. All Ethernet ports default to LAN except in the case of a USB-to-Ethernet Adapter, which defaults to WAN.
Note
When using PoE to power the router, both data and power are sent over the same Ethernet cable.
When using PoE, the router will automatically power up. Allow a short time for the router to run through the bootup sequence. Once powered up, you can activate the router using NetCloud Manager.
If you have installed the Ethernet Expansion Module (MC20-ETH), connect Ethernet cables as needed:
DC Power and GPIO Port
If you are not using PoE power, connect the power supply plug to the DC power port on the router and then plug the other end into an electrical outlet.
The router will automatically power up. Allow a short time for the router to run through the bootup sequence. Once powered up, you can activate the router using NetCloud Manager.
The 4-pin DC power/GPIO cable socket is configured to allow for using a 4-wire power/GPIO cable to hardwire power for DC connections, or for using GPIO. Refer to the following for pin configuration when making a custom cable. The recommended connector is a 4-pin 2x2 Molex micro-fit.

Note
The diagram shows the view looking into the socket on the router. Be sure to take this into account when building a custom cable.
GPIO Expansion Module (MC20-GPO)
Requires the GPIO Expansion Module (MC20-GPO) to be installed. The 3.3 VDC and 9-33 VDC current-limited outputs may be used to power application logic or sensors.
Note
When using the optional GPIO Cable†, carefully identify the bi-color wires.

When building a custom cable for use with this expansion module, the following Molex parts are recommended for electrical and mechanical compatibility:
Micro-Fit connector housing: Molex 43025-2000
Micro-Fit Reduced Mating Force (RMF) crimp terminals: Molex 46235-0001
For compatible GPIO cables, see below.
†Optional Accessories: GPIO Cables
Mating 2x10 and 2x2 GPIO cables are available for order separately.
