It seems to be well built. I powered up 8 Meraki access points with this unit. They were previously powered by independant power injectors, but I wanted to clean up the install, and there was another location that I needed to deploy a couple of single power injectors. For about the same price as purchasing those two units, I was able to purchase this 12 port POE injector, and make a swap which left me with spares for back up where I have individual injectors deployed. This unit comes with 3 sets of 4 ports that are tied together for power consumption. So there is a max power use across the four paired ports. I had calculated my power consumption to be within the limits if I used all four ports, and found that I can run four access points on four ports that are paired together for power consumption. There is a built in overcurrent protection on each of the four paired groups that monitors power use on each of the 3 groups. Each group of four ports has an LED indicator light that is green when in normal use, and goes to red when it is near max current for the group. In the instruction it says that it is likely to run in the red when you connect up four access point to one group of ports, and that it is normal and expected to run in that way. I found that in my case when I connected the fourth access point to a group of ports that the LED indicator hovered in the green, but you could see very slightly that it would get a fringe of orange tint to the green like it was on the fence of displaying in the red full use mode. I have been running the system for two months now, and have not had any issue with performance. The Gigabit performance seems to be in tact as I have not noted any network issues related to bandwidth with this unit although I have not ran a true test with gigabit throughput. One other detail that may be of help for someone is that the unit comes with the ability to change the power scheme for POE. The are two jacks as an option for A or B power which depending on which one you plug your power supply into changes the arrangement of pins that are powered up on the ethernet connections. I chose the A connection for my setup. Review: Very nice, exactly what I needed. - Life saver..... Not anything out there remotely like this. What a great idea!!! Powers up 2 Ubiquiti AP Pro access points, and 7 hikvision cameras with no issues via CAT6. Lack of planning??? The ONLY downside that I did not anticipate was the need for twice as many patch cables since SWITCH->POEINJECTOR->PATCHPANEL Plan accordingly :) Router->Switch->POEInjector->PatchPanel->WallJack->EndDevice Other Thoughts: POEout is on bottom rather than on the top row, which means the switch should be located above the patch panel. Of course you can mount upside down but then the numbers/lettering would be upside down. { SWITCH } {POEINJECTOR} { PATCHPANEL } The power supply is a separate (rather huge) power brick, and is not integrated into the unit. I can see arguments either way. I used 3m stick velcro to attach the power brick to the rear of the cabinet. This does have an interesting feature that it can accept 2 power supplies in the off chance that one goes bad. My needs are not that extreme so 1 is fine. It DOES NOT have attachment points for the power wire on the rear of the unit, I had to use several 3m sticky squares with zip ties to make it look nice and neat back there. ## Features - Instantly upgrade your network to PoE+.

The current is shared as needed - the sum of the current for each device ( watts / volts) must be less that 2.5 amps or 120 watts - each device takes the power (Watts) it needs from the common 48v source. **Q: Hi. I cant seem to locate 12v power supplies in your store. Is there a way to power 12 volt devices using this injector?** A: Yes, we have a 12 volt 60 watt power supply. Please google this part number: WS-PS-12v60w. However, you'll want to be careful using 12 volt PoE for 2 reasons: 1 - Most devices that say 12 volt / PoE actually refer to the IEEE 802.3af PoE standard, which is 48 volts. Only a few cameras have that. If you'd like to call our tech support line - 512-479-0317 - we'll be happy to check your device model to confirm this. 2 - 12 volt does not travel very far on ethernet cable. If you're doing runs any longer than about 20 ft, the voltage will drop enough that you can't use it. To see this in action, google our "PoE Calculator" to check your voltage drop for different lengths and voltages. **Q: I assume there's no way to manage these ports or power cycle them remotely from a local web ui correct?** A: Correct, the GPOE-12AB is an unmanaged, passive (power always on) injector. **Q: (Thanks for previous very valuable answers) Will passing my data through these ports affect my data throughput or my cat6 specs?** A: No, as long the cable is under 200 feet as per the info provided for CPE510. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gigabit rack mount POE injector works great. *by T***T on February 9, 2016* This unit arrived promptly.
