Hardware Installation
2. Slide the faceplate up until it
unlatches from the device.
3. Once the faceplate is unlatched, pull
it off the device, exposing the drive
bays.
Install the Hard Drives:
1. Please install a SATA HDD before
turning on the NVR. Use the key to
unlock the faceplate from the bottom
of the NVR.

5. Attach the faceplate to the front of the
device.
4. Insert a 3.5” SATA hard drive into an
available drive bay. Make sure to
align the drive connector to the SATA
connector on the bottom edge inside
the drive bay of the NVR. Gently push
the drive in until it connects. When a
drive is inserted properly, you will feel
it “seat” into the connector. Some
hard drives that are thin or oddly
shaped may need to be guided
carefully into position. If a drive is not
properly seated, the LED will not
illuminate after powering on the device.
Optional: When installing an optional
second HDD, please repeat Step 4.
To avoid data incompatibility in
RAID 1 operation, useidentical SATA
drives from the same manufacturer.
Formatted drive capacity for RAID 1
operation is dependant on the HDD
with the lowest capacity.
