UCTRONICS Ultimate Rack with PoE Functionality for Raspberry Pi 4, 19" 1U Rackmount with PoE HAT, All IO on One Side, OLED Display, Power Switch, and Cooling Fan

I had been looking at the non-POE version of this rackmount for our raspberry pis, but was hesitant because I really wanted POE. I checked the UCTRONICS website to see if they had a POE model, and surprise, it was on their website. I emailed their sales department to ask when it would be available on Amazon. They promptly replied that it would be on Amazon in about a week and stated they'd email me when it was. Sure enough, they kept their word and about a week later they emailed me the link. I ordered and it was delivered a couple of days later. I installed one pi that night and found the instructions could use a little improvement (they have since emailed me updated / improved instructions). The most difficult parts were: 1) getting the nuts that hold the display screen on the rack started on the mounting stud 2) getting the flexible circuit board of the SD card adapter installed in the upper / POE board. Tip: once you get it seated in the slot, don't pull it out thinking it will insert as easily a second time. Once you've installed one pi on the rack, the remaining go quickly (my 10 yr old son did his with some guidance from what I learned from doing the first one). Overall, the build quality and functionality are excellent - exactly as it is described to be. It definitely neatens up my server / network rack and is exactly what I was looking for. Highly recommended. Not only is the product great, but the UCTRONICs pre-sales team was helpful and the fact they emailed me improved instructions without my even asking is a pretty good indicator of the quality of the company itself. If you're on the fence about it, don't be, just get it.

Unit functions as expected. Had issues building, for a high priced item had frustrating experience installing components as the screw holes would not align perfectly. other than that works perfectly.

I'm giving this product 5 starts even though I had issues with the installation. I ended up damaging 2 of the thin flat cables on the SD adapter board because I didn't realize that before the thin cable go into the slot on the POE hat, a gray clip in front of the slot must be popped out first. Without pulling that clip out slightly, you have to force the cable in. Once you pop that clip out, the cable goes in very easily. Once you have the cable in, you can then push the clip back in the secure the thin cable in place. I actually broke the gray clips on 2 of my POE hats so I can't use the sd card adapter on those until I can get some replacement clips or possible even 2 new POE hats. I was hoping that the company would work something out for me because I don't want to replace the product because of something I did. The other issue I had was getting the display to show anything. The directions only tell you to edit the rc.local file, but there is other stuff that has to be installed, set and complied first. I had to go back to the product description to find the github link that explains it all. Other than that, this is a perfect addition to my rack setup.

I've purchased two units. Same issues across the board. The screens are sporadic, I get constant undervolt on poe (and I gave enough wattage on my switch) , so I have to use all four usb c pi adapters. The fan control is ok but if you use external power supply, they never turn off with the unit. The microsd card slots are finicky and each time get issues with corruption. The screens worked for a bit but sd card would get corrupted on removal. Just gave up on it all. Sadly had high hopes. Will need to find other alternatives.

Good-looking and problem-solving rack solutions are (unfortunately) expensive. So I was not surprised at this unit's cost - but I did expect much. I am not disappointed. I have some nits, like the HDMI cable mount is a bit flimsy, and you must remove the entire rack to add/remove/work on any unit. But these nits are far outweighed by this rack's advantages, like its front-mounted HDMI connectors, SD card slot, individual power buttons, incredibly useful mini display, and professional appearance. I love this rack! I modified the source code for the display to include each machine's hostname, and updated IP address, if it changes after host startup. I would easily buy more - but nobody has Pi's anymore. Pity all around.

This product is exactly what I needed. For those running a rack mount system this is a must if running >1 Pi 4 especially if you can take advantage of POE+. No muss, no fuss, no AC/DC. Advantages: - No AC/DC needed. If you already run POE/POE+ on your switch(es) then you will no longer need the USB-C power. This was critical for me as having to run more power to my rack introduces complexity. - I can run upto 4 PIs in a 1U with all buttons, indicators, slots, etc. right up front. This makes it super easy to maintain, access and repurpose if I need to. Disadvantages: - if I had to be nit picky I would say price. However given the quality of the product, all that it offers and its ease of use, I'm okay with what I paid others may not. It comes with everything that you need; just add your own PIs. Bonus: The LCD panel is awesome. You download a C program, compile it and run at runtime. Super easy to do and makes the rack look professional. The only suggestion here would be to display the hostname in additional to all the other details, but I can rectify that with a label. To all the nay sayers out there about assembly. I realize that this unit has done through revisions, but the revision that I have ( as of Aug 2021 ) assembly was very easy. In fact half of the unit was already assembled. All that I had to do was assemble the Pi along with the daughter cards and cables, secure with screws and done. If you ever put a kit together or ikea furniture its that simple. Highly recommended all in one unit.

I bought this rackmount a few months ago to mount several pi-4s I had. Overall it is built really well and wasn't too bad to load the pi-4s into. Is it pricey? Yes, because it's worth it. Last week I had a few of the cooling fans begin to fail. After reaching out to the company about the issue, they sent me upgraded replacements at their expense within several days to get me back up and running. UCTronics showed themselves to be a stand-up company and I'd definitely look to them for my future needs.

The OLED screens burn very easily. Pro-Tip, anything you configure for the screen should run through a simple "scrubber routine" every 24 hours or so.
