Networking NVR with 2 Switches - Unsuccessful to Date, Need Help

[Captain_B]

Problem: Dahua Switch is not being recognized by Dahua NVR.
I have tried plugging the Dahua PFS4226 switch uplink ethernet cord into the second NVR RJ45 uplink receptacle with no success but when plugging the Dahua switch uplink ethernet cord into the Cisco 110 Series switch the NVR connects to it.
Reference Points: The NVR is connected to a Cisco 110 Series switch, and the Cisco switch is connected to the internet router.
Dahua Switch and NVR have the same Default Gateway and subnet mask addresses but different IP Addresses much like the cameras.
If possible I would also like to connect the Empire Tech 10 port switch to the Dahua PFS4226 switch using the second RJ45 uplink port and daisy chain both switches to the NVR RJ45 uplink port.

The Equipment:
NVR608H-32-XI (Network Ports: 2 (10/100/1000/2500 Mbps Ethernet port, RJ-45))
PFS4226-24ET-240 (Port 25-26: 2 × RJ-45 10 M/100 M/1000 M) and (Uplink Port 25-26: 2 × SFP 1000 M uplink combo)
EmpireTech 10-Port Unmanaged Switch with 8-Port ePoE (Port 9: 1 × RJ-45 10/100/1000 Mbps; Port 10: 1 × SFP 1000 Mbps)

For Equipment reference links:
NVR608H-32-XI
PFS4226-24ET-240
10-Port ePoE Switch

Thank you for your help.

The NVR recognizes cameras...not switches. The NVR only needs one network connection point and the switches are just part of your network setup so I don't understand why you want multiple switches connecting directly to the NVR.

After a quick look at the manual I think you have to configure the Network Mode to Load Balance, for both NICs to be active at the same time. Maybe you've already done that. Disclaimer: I don't have actual experience with this so could be totally out in left field, as the saying goes.
