Connections
Your SR400ac's exterior ports are shown in the following cabling diagram.
LAN
The four yellow RJ45 Ethernet ports located on the back of your gateway (labeled LAN1, LAN2, LAN3, LAN4) are used to connect
client devices such as computers and printers to your gateway.
WAN
The red RJ45 port labeled WAN is used to hard-wire your SR400ac gateway to another network device using a RJ45/Ethernet cable.
USB
The two USB ports on your 400AC gateway (2.0 port on the back and 3.0 on the left side) are used to connect USB storage devices to
your gateway for transferring data. They also provide +5 VDC for charging other devices.
POWER
Use only the power supply supplied with your gateway.
l Do NOT open the device. Opening or removing covers can expose you todangerous high voltage points or other risks. ONLY
qualified service personnel can service the device. Please contact your vendor for further information.
l Use ONLY the dedicated power supply for your device. Use only the power adapter provided with your gateway (3 amp 12 v).

External Buttons
Your SR400ac gateway provides push-button controls on its exterior for critical features. These buttons provide a convenient means
to trigger WPS mode, toggle the Wi-Fi radio on and off, or reset the gateway. The button functions are described below.
WPS Button (5 GHz Band)
Wi-Fi Protected Setup™ (WPS) is a standard means for creating secure connections between your gateway and various wireless client
devices. It is designed to simplify the pairing process between devices. This button is located on the left side of your SR400ac
gateway.
When you press this button for 1-3 seconds, the WPS LED starts to flash. If no client pairs with your gateway after 2 minutes, the WPS
LED turns off.
When the gateway pairs successfully with a client, the WPS LED glows solid for 5 minutes and then turns off.
WiFi Button (2.4 GHz Band)
The WiFi button toggles the Wi-Fi radio on and off. This button is located on the left side of your SR400ac gateway. Look at the WLAN
LED indicator to determine the current state of the Wi-Fi radio.
To activate the radio, press and hold the WiFi button for 3-5 seconds then release. Expect a 1-3 second delay before the WLAN LED
turns on. The Wi-Fi radio is now on.
To deactivate the radio, press and hold the WiFi button for 3-5 seconds then release. Expect a 1-3 second delay before the WLAN
LED turns off. The Wi-Fi radio is now off.
On/Off Button
The On/Off button turns the device on and off. This button is located on the left side of your gateway.
Reset Button
The Reset button returns your gateway to its default settings.
This button is in a small circular hole in the back of the gateway case with the actual button mounted behind the surface. This
style of push button prevents the gateway from being inadvertently reset during handling.
Warning: Do not press the Reset button unless you want to clear the current settings.
If you want to restore the default settings, insert a thin wire (such as a paper clip) into the hole, press the Reset button for 1
second, and then release the button. The gateway reboots and returns to the current defaults.
To return the gateway to factory default settings, press the Reset button until the LEDs flash red and orange. The gateway reboots
and returns to the default settings applied in the factory. This process may take a few minutes.

Installing your SR400ac Gateway
1. Connect a LAN port on the SmartRG gateway to your PC using an Ethernet cable.
2. To connect a broadband device (such as a cable modem):
a. Connect one end of an Ethernet cable to the WAN port on the SmartRG gateway and connect the other end of the
cable to the broadbandmodem.
b. Connect one end of the cable supplied by your provider to the broadband modem and connect the other end of the
cable to the wall jack installed by your provider.
3. Plug the power adapter to the wall outlet and then connect the other end of it to the Power port of the gateway.
4. Turn on the unit by pressing the Power button on the side of the gateway.
Your gateway is now automatically being set up to connect to the Internet. This process may take a few minutes to complete before
you can begin using your Internet applications (browser, email, etc.).
If you are unable to connect to the Internet, verify that all cable connections are in place and the gateway’s power is turned on.
