M.2 SATA Installation

The XG-5100 Desktop has 8 GB of onboard eMMC storage. Optionally, a M.2 SATA drive can be installed as an upgrade or to bypass the onboard eMMC flash memory.


The SG-5100 does not support NVMe drives.


Before proceeding:

  1. Backup your 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.


The standoff for the M.2 SATA drive is not populated with a screw. A screw is provided in the original packaging the SG-5100 came in. If the original packaging is not available, a Standard M3 x 0.5 4mm Long Pan Head Screw can be used to secure the M.2 SATA drive in place.


M.2 SATA Location


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

The M.2 SATA slot is located underneath the a large heatsink/drive carrier, so the entire heatsink must be removed. The standoff is for the 2242 (22mm x 42mm) M.2 SATA drive.

  1. Remove 3 screws from both sides of the SG-5100 (6 screws total) as shown below.

  2. Turn the system over carefully to avoid scratching the top of the appliance. Remove the 2 screws as indicated below.


    Remove the Bottom Screws

  3. Remove the cover.

  4. Remove the 4 heatsink screws as indicated.

  5. Gently lift the heatsink away from the memory as shown and remove it. Be careful of the thermal transfer pad above the memory and connecting the heatsink to the chassis


    Note the Memory Thermal Transfer Pad


    Note the Chassis Thermal Transfer Pad


    Be sure to replace these thermal pads if they come off during the upgrade process.

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


    The M.2 SATA card is keyed. Do not force it into the slot.

  8. Locate the Thermal Pads that came with the SG-5100. There will be two in a plastic bag. This procedure will use the larger one.

  9. The Thermal Pad has film on both sides. One side is shiny and is sticky. The shiny side will stick the heatsink. The non-shiny side is “tacky”, but not sticky. The tacky side will go to the M.2 SATA drive.

  10. The Thermal Pad will attach to the large aluminum heatsink.

  11. Remove the shiny film from the Thermal Pad and stick it to the heatsink as shown. Try to center it on the cutout, but it doesn’t need to be exact.

  12. Remove the film from the non-sticky side of the Thermal Pad.
