M.2 SATA Installation

The SG-2220 has built-in onboard eMMC storage. Optionally, a M.2 SATA drive could be installed as an upgrade or to bypass the onboard eMMC flash memory. The SG-2220 can support a 2230 (22mm x 30mm), 2242 (22mm x 42mm), or 2260 (22mm x 60mm) M.2 SATA drive. For this document, the 2242 M.2 SATA was used.


Before proceeding:

  1. Backup the configuration file, if possible.

  2. Unplug the system for at least 60 seconds to ensure all phantom power has dissipated.

  3. Anti-static protection must be used throughout this procedure.

  4. Any hardware damage incurred during this procedure is not covered by the hardware warranty.


By default, the M.2 SATA drive will be the first drive recognized by the Netgate® device. pfSense® Plus software must be reinstalled on the M.2 SATA drive.


The SG-2220 does not support NVMe drives.

The M.2 SATA slot is located underneath the SG-2220 system board, so the entire board must be removed.

  1. Remove the four (4) case screws, two (2) on each side of the case.

  2. Remove the four (4) system board screws.

  3. Gently slide system board away from the front faceplate until the board is free, then raise the back to pull it free.


    Do not force the system board out. Gently remove it.

  4. Once the board is removed, turn it over to identify the M.2 SATA drive location.


    The SG-2220 supports a 2230, 2242, or 2260 M.2 SATA drive form factor.

  5. Remove the screw and spacer from the system board.


    Do not lose the spacer. The spacer is required to go between the system board and M.2 SATA drive for proper installation.

  6. Insert the M.2 SATA drive into the slot at about a 30° angle.


    The M.2 SATA card is keyed. It is possible to incorrectly place put the card in upside down, but it will not go in easily. Do not force the card into the slot.

  7. Carefully align the spacer between the system board standoff and the M.2 SATA drive.

  8. Press the M.2 SATA drive down and secure it with the screw.


    Ensure the spacer is between the system board and the card.

  9. Gently slide the system board back into the base of the chassis.


    Ensure the Status LED Pipe is protruding correctly through the chassis.

  10. Replace the lid on the chassis.


    The lid should be oriented so the processor heat sink and lid vent are aligned properly.

  11. Replace the case screws. Use a hand screwdriver and be careful not to crossthread the screws.

  12. Reinstall the pfSense® Plus software on the new M.2 SATA drive.

  1. Restore the configuration backup if one is available.
