powerbox pro setup as switch/ no IP from DHCP client from NVR

Tue Apr 29, 2025 6:06 pm

Hi,
I followed the basic procedures to set up the Powerbox pro as a switch to connect to the NVR:

• Factory reset device with no default config
• Create a new bridge and all add all ports to bridge
• Set dhcp client to bridge
• Plug ethernet cable from NVR in powerbox port 1
• Powerbox will request IP from NVR

seemes powered on correctly through port 1, PC connected to port 2 but for some reason the powerbox is not getting any IP from the NVR

ok so tested with my isp router and working perfectly!! must be something with the NVR DHCP server? any ideas?

ciao,
Antonio

jut got this message from Reolink..

at this point is there a workaround we could do on the powerbox pro to get around this issue below?? the IPs assigned to the IP cameras are in the order 172.16.25.XX/24

what is said below is probabaly not fully true as the ips of the cameras begin with 172.16.25.2, making me guess that the internal router is 172.16.25.1 anyhow this is the message:

Dear Antonio,

Thank you for using Reolink. This is the Reolink support team.

Thank you for reaching out to Reolink support regarding your issue with connecting an NVR to a PoE switch. I understand you're having trouble with the NVR not assigning an IP address to the switch, and I'd be happy to help clarify this situation for you.

First, I want to address a misconception in your setup. The Reolink NVR (RLN8-410 in this case) is not designed to function as a DHCP server for external devices like switches. Instead, the NVR is typically configured to receive an IP address from your network's DHCP server (usually your router) or to use a static IP address.

Here's what's likely happening:


The NVR is not assigning an IP address to the switch because it's not meant to perform this function.
The switch, set as a DHCP client, is looking for a DHCP server on the network to assign it an IP address.


To resolve this issue and set up your system correctly, I recommend the following steps:


Connect your NVR directly to your router using an Ethernet cable.
Connect your PoE switch to your router as well.
Set both the NVR and the switch to obtain IP addresses automatically from your router's DHCP server.
Connect your cameras to the PoE switch.


This setup will allow your router to manage IP address assignments for all devices, including the NVR and the switch, while the PoE switch provides power to your cameras.

If you prefer to use static IP addresses, you can manually assign them to your NVR and switch through their respective configuration interfaces, ensuring they are within your network's IP range and do not conflict with other devices.

I hope this explanation helps clarify the issue and provides a solution for your setup. If you have any further questions or need additional assistance, please don't hesitate to ask.

Have a wonderful day and stay safe.

Best Regards,
Reolink Support Team -

Cant you just assign a static ip in the corresponding subnet?

hi,

was just about to post that I set an IP in the same subnet top the switrch bridge and connected the camera to the Powerbox pro. it works like a charm.

is it normal that the port led on the power box is red??

If you are using PoE out, the red should mean that PoE out is ON.
https://help.mikrotik.com/docs/spaces/R ... 69/PoE-Out
PoE-Out notifications
PoE-Out LEDs
Models with dependant voltage output

PoE-Out LED behavior can differ between models, but most of them will indicate PoE-Out state on one additional LED. Devices with one voltage output will light:

Red color LED - PoE-Out port state is powered-on (auto or forced-on mode).
Blinking Red color LED - PoE-Out port state is short-circuit

Can the Reolink NVR not be put in bridge mode?

That's a pity, the system I have you can change the ports in the NVR into a switch

yes , for some reason they took out the management of the internal router of the nvr...well i guess they don't want pewople messing with that but i mean even to change the internal ip subnet if someone wated to or to change the dhcp settings.. could have been useful..
