We bought this to replace a NetGear GS110TP to give us a bigger PoE power budget, and it also promised extra features like DC out, Modbus connections, and PoE+ and ++ (up to 90w) on all ports.
This was bought from Amazon for £379 in July 2024.
I was looking forward to this being a big upgrade from the previous switch, for starters that I wouldn't need to worry too much about voltage levels from our solar PV system due to it's wide range of acceptable voltage.
Right now it is connected to a 12V system, but soon this will be upgraded to a 48V system (to be reviewed later!), and no changes will be required.
It was quite easy to set up, although a review on amazon says that they had to plug a console cable in to it to enable the web GUI, which I thought I would have to do, but I could not find a console cable or speed settings that would work.
The switch only came with a quick start guide in the box, which said to use the included console cable (not included), and no other instructions. The main user guide has to be downloaded from their website.
In the end, I used wireshark to determine that the default IP is 192.168.1.200 (although this is mentioned in the manual, which I didn't have at the time), so I just logged in with the default credentials and everything was fine.
I had 2 problems right from the start, one was the voltage usage graphs were empty, and 2 devices that only worked at 10mbps (which had worked on the NetGear switch), did not work on this new switch. The port lights were active, and the switch detected a 10mbps, Half Duplex connection, but no MAC addresses were seen, and the devices were not contactable. I tried forcing speeds and duplexes instead of leaving it to Auto-negotiate, but this made no difference, even disabling and enabling the port between each change.
I contacted the Linovision support, and they did respond quite quickly, and said to upgrade the firmware, which they gave me a link to.
This upgraded the device from 1.1.1d to 1.1.1i. It did not fix the problem of the 10mbps devices, but it did explain the empty graphs - the menus are now labelled "Solar System Configuration" and "Solar System Working Curve", which makes more sense, and probably applies to this model instead.
During the firmware upgrade, it rebooted, and forgot all its settings, which is not ideal. I did take a backup of the config first, but none of this is mentioned before you start the process.
SNMP is not implemented correctly. There is no way to change the contact details or location. Statistics from the ports are crazy:
There is no way I have transferred more than 1TB within 24 hours through this switch that has 2 CCTV cameras, 2 Raspberry PIs and 1 laptop.
It should look more like this (graph from the other end of the connection onto a Cisco switch);
Now I don't expect the graph to be exactly the same, but it should show a similar shape - It's not even that the graph Y-axis is the wrong multiplier, it's just totally wrong!
Telnet is available and can be disabled.
The commands are similar to Cisco, which is nice, and via telnet you can actually change the switch name, woohoo!
For example, "show interface" gives the following information:

None of that can be right. My connections seemed stable!
There is no way of configuring SSH in either the web GUI or via telnet - although the port is open I was not able to log in.
I was really looking forward to this switch, but the experience was disappointing.
If they cant fix the 10mbps problem, I will just have to buy a small PoE-powered hub that properly supports 10mbps and hang it off this switch, which is an expense I had not budgeted for,
I expected more from what is quite an expensive switch from an unknown make.
I am not inclined to try any more of their products or recommend them to anyone else, which is a shame, as the two switches with integrated solar charge controllers would have been great for a friend's project.
