There are two keystone jacks above the JetKVM that I have connected to the hdmi and usb (data only, I am powering the JetKVM on a separate usb port) on the back of the JetKVM. This way I just use a short usb/hdmi patch cable to connect to whatever device I need to work on. I have the power usb for the JetKVM on a usb keystone on the back of the rack so I can unplug it and reboot it if need be.
The author remixed this model.
I moved the pc over and added a JetKVM mount.
