I spent hours installing this in my rack (which is very difficult to move and get to back), cabled to Tripp Lite KVM rack device, only to find that port 3 doesn't work. It was my fault for not testing all the ports before installation, but it is WAY too much trouble to remove, send back, to get another. Fortunately I don't need all 8 ports.The product description says that cables are included for easy hook up. Only two cables are included - you need to by 14 more to hook up to all ports....The device works well, though the cables all have both PS2 and USB ends, so I end up with the PS2 ends unused and have to Velcro them up. The software isn't the greatest UI, but it does the job. The resolution is a bit funky, but it certainly provides the console access when you need it, so overall it works well. Documentation is a bit thin, I'd like to figure out how to change the authentication model so that it goes against by AD credentials, but no luck there yet. It would also be nice to be able to change the certificate so that it can pass certificate checks, but no luck there either.It's possible I got a bad unit but this switch is marginal at best for what I think a $600 unit should be. It is very slow switching between sources. The video feed is noisy which varies from slightly annoying to unusable. The USB sometimes needs to be unplugged to make the keyboard work. I didn't really need an 8 port unit but wanted the nice rack mount size. I swapped in another cheaper 4 port unit we had around and the difference is night and day in terms of switching speed, video clarity, and lack of USB problems (only changed the switch, not any of the cables). We will buy something different to permanently replace this unit.Great product. No problems I used many other KWM's but it was always something. Small glitches. I use this one now for 3 months no problems. The only minor complaint is that I had to buy their cabling. Since everything works not a big deal. I use it to switch between 3 or 4 work stations. Bought one more last week for my second desk.easy install, easy to use.
