drives into the available drive
bays until they are firmly
connected to the SATA slot on
the server.
Note: The upper HDD bay is the primary HDD bay, the bottom HDD bay is the secondary HDD bay.
If you want to install only 1 HDD, use the upper HDD bay.
The hard disk in the upper HDD bay is initialized as Volume_1 (/mnt/HD_a2).
The hard disk in the lower HDD bay is initialized as Volume_2 (/mnt/HD_b2).
You can secure the HDD’s by fastening
them to the CH3MNAS with the
included HDD screws.
