Summary: If you have a small rack with 3+ servers and need PS2 KVM connections, this is a great little box. It can be either a desktop or rackmount setup (and comes with the rack kit), and you can add up to 4 machines. We're using it in our parking lot rack, and it's worked pretty well so far.
Summary: I sent this back twice and finally gave up. flimsy and no power supply although it is mentioned in the parts and directions. Too much money for this crap sorry for the negativity but I needed something and was in a hurry and this did not fit the bill
Summary: This little switch works almost perfectly with our Macintosh G4 Digital Audio tower and Intel Mac mini. Keyboard is the Apple USB keyboard provided with the G4; mouse is the wireless Microsoft Intellimouse Explorer, using the USB Overdrive X driver on both Macs.
Summary: This switch simply works. No complicated setup, no software to install. Just turn off both computers. Plug the shared keyboard, monitor, mouse, speakers and microphone into the switch, connect the included cables into the switch and the two computers.
Summary: Very sturdy all metal case. Works great. Minor Point: The red (power) LEDs tend to swamp out the current selected system (green) LED. The "scroll-lock,scroll-lock, number" sequnce is very easy to get used to. Note KVM supports the monitor ID protocol required by some systems.
Summary: I originally had a very very old No Brand 4 port chained on a ConnectPro PR-14. It had worn out switches and didn't have keybrd switching. I purchased the Trendnet TK-401R to replace the one with worn out switches. I didn't want to reroute/change cables to go to an 8 port switch.
Summary: This is an excellent unit with all connections on the back which helps with cable management. It also has low-volume audio feedback for the hot-keys which is better than my prior KVMs. However, I was surprised to find it has four male video connectors for the controlled computers.
