Step 2. Connect the shared USB keyboard, mouse to the KVM switch.
Step 3. Connect each of your computers to the KVM switch, using the DVI videocable.

2.2 Power Up Sequence
Double check whether all cables/connectors are properly connected. You can check the keyboard
and mouse connectors to ensure the connectors and cables are connected correctly.
The recommended Power Up sequence is as follows: Monitor, KVM Switch, finally the
computers.
Verify that all servers connected to the KVM Switch are powered on. If any connected servers have
not been powered on, it is okay to do so at this time (servers can be powered on simultaneously).
The KVM Switch emulates both a mouse and keyboard on each port and allows your server to boot
normally.

Now that you have connected your console and servers to your KVM Switch, it is ready for use.
You can control the KVM switch by two methods:
1. Using push buttons located on the LED panel of the KVM Switch
2. Using hot-key commands through the console keyboard
It takes few seconds for the video signal to refresh after switching servers. Re-synchronization of
the mouse and keyboard signals also occurs. This is normal operation and ensures that proper
synchronization is established between the console and the connected servers.
