mSATA Installation

The SG-4860/8860 1U have built-in onboard eMMC storage. Optionally, a mSATA drive could be installed as an upgrade or to bypass the onboard eMMC flash memory.


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 mSATA drive will be the first drive recognized by the Netgate® device. pfSense® Plus software must be reinstalled on the mSATA drive.

The mSATA slot is located on the top of the SG-4860/8860 1U system board. The mSATA slot is directly behind the Ethernet ports. There are two other similar ports on the top of the board, but they are mPCIe ports. The mSATA drives are not electrically compatible with mPCIe connectors.

  5. Insert the gold leads of the mSATA drive into the slot at the angle shown.


    Be sure the drive label is facing up and can be seen. The drive slot is keyed and the drive can only go in one way. Do not force the drive into the slot.
