The SG-4860 has built-in onboard eMMC storage. Optionally, a mSATA drive could be installed as an upgrade or to bypass the onboard eMMC flash memory.
Backup your configuration file, if possible.
Unplug the system for at least 60 seconds to ensure all phantom power has dissipated.
Anti-static protection must be used throughout this procedure.
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 pfSense® software. pfSense must be reinstalled on the mSATA drive.
The mSATA slot is located on the top of the SG-4860 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 electically compatible with mPCIe connectors.
Remove the four (4) case screws, two (2) on each side of the case.
Many of our desktop systems use tri-lobe self-threading screws. Only use a hand screwdriver and be very careful when screwing them back in. They are very easy to crossthread and will strip the threads of the case.
Remove the lid from the base of the chassis.
Remove the screws from the mSATA standoffs.
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.
Push the mSATA drive down until it is parallel with the system board and replace the screws to secure the mSATA drive in place.
Replace the lid and case screws. Use a hand screwdriver and be careful not to crossthread the screws.
Reinstall the pfSense software on the new mSATA drive.
Restore your configuration backup if you have one.
