Tom's Hardware KVM Obstacle Course, Continued
Test 8 - The purpose of Test 8 was to see how the KVM unit responded to power loss. We turned the KVM off, or pulled the power to the KVM. For those units that were powered by the PS/2 or USB port, we pulled the cables out and plugged them back in, once we were sure that the KVM was receving power. Once power was restored to the KVM, we attempted to switch between both systems and used the keyboard/mouse. If we were able to switch between systems and the keyboard/mouse worked, we considered this test a "pass." If the KVM or the system locked up, we considered the KVM to have failed the test.
Test 9 - In this test, while the KVM is switched to System 2, we turned the power off on System 2. We then re-applied the power to System 2 and checked for keyboard/mouse function. What we were looking for here was whether dropping the power while the unit was switched to that system had any effect on switching. We considered a "pass" in this test as having access to both systems when the power was restored and being able to use the keyboard/mouse.
Test 10 - The focus of this test was to test a combination setup on KVMs that support such a setup. In this test, we used the PS/2 port of the KVM to switch the keyboard between systems and the USB port port two on the computers. We use two mice for this setup and plug each of the mice in. The KVM has no pointing device connected to it. We rebooted both systems to see if the KVM functions by switching between the systems. The KVM is considered a "pass" if both the keyboard and the mouse function. KVMs that don't support both PS/2 and USB switching or USB only switching were indicated with N/A.
