RLN36 could hold 3 internal HDDs (up to 16 TB/piece) to provide fairly large storage space. If you want to install HDDs for your RLN36, check out the following steps.

Step 1. Remove the screws of the NVR with a screwdriver and open the outer case.install_hdd-1.png

Note: The 2 side fans have been removed from the latest RLN36 to reduce noise. There is only 1 cooling fan on the motherboard. But the HDD installation guides below are still helpful.

Step 3. Flip the NVR over, locate the screw holes and screw the HDD to the back of the NVR.
