LINOVISION Industrial 8-Port Full Gigabit POE++ Switch with 4 BT 90W PoE Ports, 2 Gigabit SFP Uplinks, POE Budget 120W, POE Watchdog, DIN-Rail POE Switch for PTZ Camera/POE Lighting/ POE Monitor

Industrial grade product. I’m a network engineer. I’ve used Linovision products in very demanding environments. It is all rock solids. It delivers advertised bandwidth (speed) while working in extreme environments. I’ve personally tested to >160°F and <5° F.I did have an issue with one AC power cord. One email and a new one was on my doorstep in 40 hours.Use this stuff.

We are using this in our mechanical boxes at baseball fields to feed internet via fiber to ethernet. Works great even in the Florida heat!

Installed in my Tampa, FL attic. Still going strong 1 year later.

The previous owners of my home ran network cables to every room. They used them for telephones (remember those?), so each line ended up in the attic where there was a punchdown block. When I repurposed those lines for Ethernet, I was sorta stuck putting my switches up in the attic, where the lines ended. But it gets HOT in my attic, since I'm in Texas. So I bought two of these switches because they could handle the heat, and also supply my security cameras with power via POE. I ALSO bought another similar switch from a different manufacturer...it was still an 'industrial' switch with the same heat resistance, but without POE and hence a bit less expensive. This was to feed switches in each room where the other ends of the cables were. All three switches are connected via a patch cable.Well, long story short, last week we had a lightning strike on a ham radio antenna about 100 feet from our house. While the antenna itself wasn't connected (I leave them unconnected when not in use, for this exact reason), the bulk of the strike went to ground through the mast, and caused a surge. That third 'industrial' switch couldn't handle the surge, and not only did it fry that switch, it in turn sent a surge out through all its ethernet ports, and fried all the switches connected to it...that is, all except the Linovision switches! The Linovision switches didn't skip a beat. So they've handled the Texas heat in my attic, and a power surge that destroyed a bunch of other equipment. I ordered this newest one to replace the fried switch, and I'm now back up and running.

This POE switch is more have industrial use than normal household in mind, it is designed with using railed power supply. Although it includes a power supply adapter for regular power outlet, there are power connectors exposed outside the case. Something to be aware of.It has for POE ports that supply higher wattage output of 802.3bt standard and four POE for 802.3 af/at. There are two SFP ports for none POE uplinks. While SFP ports may be popular in data centers, I don't see the logic to have both none POE ports are SFP instead on at least one using regular RJ45 port. It forces user using the SFP to buy an additional SFP to RJ45 adapter in order to connect this switch with their network.While I have no issue using this switch directly with POE devices using up to 24W of power, I ran into problem using a 802.3bt compatible POE extender, and the main reason for me to get this switch in the first place.While I don't have any POE devices require high wattage output of bt, I do have a number of POE devices that require up to 24W at peak use. While normal bt switches can support these devices without problem, I was hoping to simplify the cable routing by using one cable to a cluster of devices and then use an extender to connect them. This requires a switch and an extender to support the bt high wattage output between them in order to have sufficient for the extender to support those devices.Well, as it turns out, my plan did not work. Not only the extender was not able to support multiple devices, but it was also not even able to support one 24W POE device, in other words the pair could not even handle 820.3at power level. Granted, this compatibility issue may not be this switch's fault. It could be the extender is the problem, so I move the extender to an 802.3at switch to test, and it was able to power up the 24W device without problem. It is clear that when 802.3 hand shack between this switch and the extender did not workout, this switch falls back not to 802.3at but to the even lower power output of 802.3af.At the end, I was not able to archive what I has hoped with this switch.

Very hard to find a good PoE++ switch that can reliably handle multiple 60-90w devices. I have two NUC (gen 7 and 11) i5 boxes with PoE hats hooked up to this; power has been rock-solid. Speed takes a slight hit vs conventional ethernet data, but small price to pay for flexibility. Heat has not been an issue running 24/7, just keep the unit and adapter in a ventilated space. The switch is also fairly quiet which is a nice surprise vs other PoE switches (including non ++) with loud fans.I plan to add a few cameras/other small devices to the other lower power ports, and have not tried the high speed SFP, but so far very happy.

purchased this to install out in my shop. ran some fiber to uplink to my unifi network in my house and works flawless. provides power and network for my cameras and an AP so i have wifi in the shop when im working. i have it mounted in the peak by the air vent next to a vent fan. only had about a month, but it's working great so far. no complaints other than the latch that doesn't seem to lock on well.

It did the job, work like I expected
