Operation
Hot Plugging
The switch supports USB hot plugging. Components can be removed and added back into the
installation by unplugging their cables from the CPU ports without the need to shut down the
unit.
Powering Off and Restarting
To power off and restart the switch:
1. Disconnect all of the computers from the switch.
2. Disconnect the external power cable from the switch rear panel.
3. Wait 10 seconds, then plug the external power cable back into the switch rear panel.
4. After the switch is powered up, reconnect the computers.
Port Numbering
Each CPU port on the switch is assigned a port number. The port numbers are marked on the
switch rear panel. The Port ID of a computer is the same as the CPU port number to which it
is connected. For example, a computer connected to CPU port 3 has a Port ID of 3.
The Port ID is used to specify which computer gets the KVM focus, USB peripherals, and
audio focus with the hotkey port selection method.
Hotkey Operation
The switch provides an extensive, easy-to-use, hotkey function that makes it convenient to
control and configure the KVM installation from the console keyboard. Hotkeys provide
asynchronous (independent) switching of the KVM focus, USB peripherals, and audio focus.
