Basic Connections

  1.  Insert one end of an Ethernet cable into the LAN/PoE port on the device.
  2.  Insert the other end of the Ethernet cable into the PoE LAN port on your FortiGate appliance. Ensure that FortiGate and FortiExtender are on the same subnet.
  3.  Optionally, if you are not using PoE, connect the device to a power outlet using a power adapter.

You must provide adequate grounding to the PoE injector of the FortiExtender unit, if required, in compliance with your local electrical code or regulations. This device complies with IEEE 802.3af/at PoE specification. Do not use a PoE injector that is not IEEE 802.3af/at compliant as it might damage your device.


  1.  Remove the dust cover that protects the SIM sockets and fits over the antenna posts.
  2.  Insert your MicroSIM (3FF) SIM card(s) into the SIM socket(s).
  3.  Observe the following guidelines:
    •  If installing one SIM card, you can insert the card into either SIM socket.
    •  If installing two SIM cards, use SIM1 as the primary socket and SIM2 as the secondary.
  4.  Insert the SIM card(s) into the SIM socket(s), making sure that the card is facing down with the cut corner on the right. (If necessary, press the card again to remove it.)
  5.  Replace the cover, and then attach the antennas.

IP Configuration

After you have connected the FortiExtender network interfaces, the device automatically attempts to obtain an IP address from a DHCP server. If you do not use DHCP, you can configure a static IP address.
To configure a static IP address:

  1. Use an Ethernet cable to connect one of the LAN ports in the back of the
    FortiExtender to the Ethernet port of your computer.
  2. Set the computer Ethernet port to DHCP mode, and connect it to port1, port2, or port3.
  3. Open your web browser and point to the default FortiExtender web GUI address:
  4. In both the username and password fields, type admin and press the Enter key on your keyboard.
  5.  Go to Networking>Interface, where you’ll see all the system interfaces.
  6. Select a desired interface, set it to “static” mode, configure the static IP address, and click Save.


The FortiExtender device is designed for placement near a window (desk or wall mount) to achieve the best LTE signal strength. Refer to the diagram below for proper placement and mounting.

Install SIM card(s)

  1. Unscrew the SIM card sockets cover on the bottom of the unit.
  2. Push the screw tab outwards, and unlock the cover from one end to remove it.
  3. Insert your MicroSIM (3FF) SIM card(s) into the SIM socket(s).
  4. Replace the SIM card sockets cover, and fasten it onto the unit housing with the screw.

Place on top of a desk or flat surface

  1. Attach the rubber feet to the four corners on the bottom of the unit.
  2. Place the unit on the desk or flat surface.
  3. Secure the unit in place with a Kensington lock.
  4.  Attach the antennas.

Hang on a wall

  1. Peel off the drill template sticker, and stick it onto the wall in a desired location.
  2. Use the template to mark and drill the pilot holes.
  3.  Insert the anchors into the holes.
  4. Insert the screws into the anchors and tighten, leaving around a 5-mm gap between the screw head and the wall.
  5.  Position the device so that the mounting holes line up with the screws.
  6. Place the mounting slots over the screws and slide the device down until the screws fit into the slots.

Tip: Use bear claw screws. The screw heads of bear claw screws have a built-in gap that fits well with the hanging holes. You can purchase bear claw screws from a local or online hardware store.

Fasten onto a wall

  1. Peel off the drill template sticker, and stick it onto the wall in a desired location.
  2.  Use the template to mark and drill the pilot holes.
  3.  Insert the anchors into the holes.
  4. Snap off the plastic cover over the LEDs on the front to reveal the long screw holes.
  5.  Insert the long screws through the device from front to back.
  6.  Insert the long screws into the anchors on the wall and tighten.
  7.  Replace the cosmetic cover over the LEDs on the front. Refer to the illustrations on the next page.
