TRENDnet 8-Port USB/PS2 Rack Mount KVM Switch, TK-803R, VGA & USB Connection, Supports USB & PS/2 Connections, Device Monitoring, Auto Scan, Audible Feedback, Control up to 8 Computers/Servers

I rarely have time to review Amazon purchases. But I am absolutely stunned with the performance of this TRENDnet KVM switch. It took me less than 30 minutes to open up the shipping box, connect up five of my linux (Fedora 20) workstations (each with 64 cores!) and start testing all at a turtle's steady-and-slow pace.To switch the monitor between different workstations, I did the following:1) Hit the "Scroll Lock" twice on the keyboard (top right hand corner) => beeped (meaning enter the workstation numbers 1-8 to go to)2) Entered "4" on the numeric keypad (the numbered keys in rows/cols to the right of keyboard not on the typing pad) => beeped again (meaning the monitor has been switched to the desired workstation)3) Voila!Instead of "4" in Step 2) above, you could also hit the vertical up arrow on the numeric keypad and go to next available workstation. Do not do it unless you have all eight computers hooked up. Simply type the number of the computer that you wish to go to after hitting the "Scroll Lock" twice.Buy it! Think twice not! Do not forget to purchase KVM cables to hook it up. No cables are provided with this box. It is of course possible that it may not work for your set up but there is nothing universal in this world. The great thing about Amazon purchase is that you can return it with full refund should it not work for you. That is why we all love Amazon.This switch ranks among one of the top purchases I have ever made in my life. It is simply divine, particularly bearing in mind the price.Thank you Amazon for providing this great product.Thank you TRENDnet for inventing an awesome gadget. I am indeed following the trend. So should every other Amazon customer. Please follow the trend. Do not be left behind all alone.

I installed this KVM switch last night and used 13 of the 16 ports. The sever group is a large mix of machines - 1 Linux, 3 win2k, 6 server 2k3, and 2 sever 2k8 boxes. Some are dell boxes, some supermicro, some custom. All worked flawlessly.This KVM does NOT come with cables, you will need to purchase them separately. I purchased 16x of the 6' foot cables (TK-CU06) also on Amazon at the same time. They come in 6', 10' and 15'. The mouse and keyboard part of each port are carried on one USB plug that piggybacks on the VGA cable. The power cable is an AC adapter, it would be nice if it was a straight power cable with the unit having an internal power supply, but that's not a huge deal.What I did was I bought male to female VGA extension cables for each server that was more than 6' away from the switch and it worked perfectly. This was cheaper than buying the longer KVM cables. The standard VGA extension cables carried the USB signals just fine so I was able to plug them directly into the switch, and then plug in the 6' VGA/USB KVM cables at the server end, which also helped keep things very clean. (if I used the KVM cables direct into the switch, I would also need USB extension cables)I really like how this KVM has a separate button for all 16 ports and a red LED for something being live/connected. So far I consider it to be MUCH better than the Belkin PS2 unit that it replaced. To be fair though, the Belkin is 7+ years old.Overall, I am extremely happy with the purchase, setup and function of this switch. I highly recommend it, granted one plans ahead of time with the proper purchase and install of cables.

This KVM is basically unusable and unreliable.I was so excited to finally be able to have a nice KVM solution for my server rack. After an easy install, easy hookup I thought it was going to be a breeze! After running 3 days, the system locked up.This wouldn't have been such a problem if it had a front panel power switch...as it turns out, you must unhook ALL cables that provide any power (including the power adapter of course AND ALL USB/Monitor cables going to the back) to kill the power.Being a server rack, sandwiched between two full length servers made this process cumbersome at best and a friggin nightmare at worst when there was a problem with a server and I needed keyboard control ASAP.Do not buy this unit no matter how awesome the price looks. There is a reason.
