I have several servers on my KVM switch. I have a monitor, keyboard and mouse being shared by all. some of my servers are not showing up on my monitor nor responding to the keyboard. I can Remote into one of the the servers and I can verify the other is working by checking all the other workstations that connect to it. Any trouble shooting tips on KVM switches. Both connect to the switch with a standard monitor cable and PS2 connctors. One of the servers uses a converter cable to convert USB to PS2.
