Cudy POE400 90W Gigabit Ultra PoE++ Injector Adapter, IEEE 802.3 bt /802.3at/802.3af Compliant, Up to 90W Ultra Power Supply, 10/100/1000Mbps Shielded RJ-45, Plug & Play, Metal housing

Firstly, the good news this was the only 802 that I had been working on. I recommended three BT injectors that I successfully negotiated at the BT power level with my WIFI access point. However, the LAN connection that we obtained through the POE injector was far from ideal. I initially encountered an issue with the network negotiating only 100M and not the 5G link the switch was supposed to It appears that disconnecting and reconnecting the LAN cable a few times fixed the issue and the switch reported a full 5G link at the end. In the past few days my WiFi performance has been horrible, and streaming media has been very sluggish. I had tremendous trouble troubleshooting this problem until I noticed the switch was reporting network errors. I swapped some cables and it worked. There were no problems with any of them. As soon as I removed this POE injector from the path, the errors went away. basically, this POE injector didn't pass the data straight through, but instead introduced errors into the data stream. The whole experience has disappointed me!.

My primary wifi access point in the center of my home is fed by an ethernet line that uses PoE. I needed an injector to add PoE to this line. A few minutes later, it worked perfectly, and the access point showed that enough power was being provided. My experience over the last few weeks is that the injector's power supply becomes faulty if it is turned on and off too quickly. The injector would stop supplying power if, for example, the power to the house went out for 10 seconds and then came back on, or if I briefly flipped the breaker off before coming back on. My experience was that this injector must be unplugged or turned off for at least a few minutes prior to being turned on, to ensure that it works It made it another device to maintain and also a security risk and liability if it were to be turned on by mistake without me being home, as many smart home devices depend on the wifi access point being fed from it. It seems that this gadget should at least function reasonably without an uninterrupted power supply backup, and though I may still do so, I thought it should work at least reasonably well without one. At last, I decided to replace this injector with a more reliable one that works reliably for short periods of time.

Powering a Unifi LED panel with this piece of equipment was my goal. During the first 10 seconds, the injector worked, but then it stopped. No longer able to power anything. Despite not thinking the 90W injector would really work, I bought another one for $27 and it powered the light without error.

I purchased this PoE adapter for powering a Zyxel access point that requires over 30W. Despite being sturdy and delivering power as described here, the unit is not fragile. In addition to not becoming hot, the device is extremely well constructed, making it a more cost-effective alternative to.

It powers any POE device and is a nice size. I use this POE++ power brick in underground buildings to power Verizon LTE extenders. The network and device are connected once the Ethernet cord is plugged in.

The 36x PTZ camera I purchased it for needs power for this to do the job! I think it's a high quality product and it.

An output of 90W will not be achieved by this device.
