I hate to oversimplify here. You’ve tried replacing the KVM, how about trying to try a different keyboard?

You have to check the equipment… My experience with this type of device it for more that five years with a dirferent system and OS. You did’nt mention how many computer does KVM works and if you tried to exchange the conection with other if apply. Ensure that equip. it ok using another comp.

Good Luck

I had the same problem in a testlabo.
Especially with NT-Server. When you are connected to the server when it boots, no problem. When you are connected to another channel of the KWM when the server boots, you can’t use the keyboard.

Did you do a cold start on the KVM after you changed the keyboard?

The first thing you should do is plug the keyboard in directly to the CPU to ensure that the keyboard is working. If it works then try the KVM with a different keyboard. If it still doesn’t work, the next thing you would need to do is change the cable from the KVM to the CPU with a known good cable (and a known good keyboard. It is highly unlikely that you would have two KVM’s with the same problem. I suspect it is the KVM cable if the keyboard is sound.

Older mechanical switched KVMs coupled with certain boards have trouble such as described. The workaround for them IME has been to get fully booted up b4 using the switch; that is, changing to another computer to boot it up. Even then, I have had certain mainboards lose the kb connection when switching. I am currently using a fully electonic KVM which has worked flawlessly for me, switching between my desktop and the adjacent racked server in the tech closet. This Ktc KVM advertises that it maintains these connections for you, so evidently they have recognized this problem as well.

I would also ask that if you haven’t yet, make sure that the kb port(s) have not been damaged. I have seen (not recently) kb ports rendered inoperable from hot-swapping keyboards on certain mainboards. As always, test your cables and connections for continuity and correct installation.

Hi,

Try a different keyboard.

Take a look at others facing such problem http://help.lockergnome.com/index.php?showtopic=27002

I have experienced the Keyboard and Mouse will not work on one of my KVM. Some (Belkin) KVMs need to be on the correct channel during the boot process to know that need provide the “Stay Alive” signals. After booting the computer while on that channel I have had no problems.

Not all servers support that you unplug the Keyboard. It’s common that you need to restart the server to get the keyboard running again. Try this before you try anything else.
