Port Numbering

Each CPU port on the KVM switch is assigned a port number

1 or 2 for the SV231USBAN; 1 to 4 for the SV431USBAN). The port numbers are marked on the rear panel of the switch.

The Port ID of a computer is derived from the CPU port number to which it is connected. For example, a computer connected to CPU port 2 has a Port ID of 2. The Port ID is used to specify which computer gets the KVM, USB hub, and audio focus with the Hotkey port selection method.

Powering Off and Restarting

If it becomes necessary to Power Off the KVM Switch unit do the following:

1. Power off the switch, then unplug the KVM cables from the switch's rear panel as well as the power adapter cable.

2. Wait 10 seconds, then reconnect the KVM cables.

3. Plug the switch's power adapter cable back in.

Hot Plugging

The KVM switch supports USB hot plugging. As such, computers can be removed and added back into the installation by unplugging their cables from the CPU ports without the need to shut the unit down.

Operation

There are two convenient methods to switch the KVM, USB hub, and audio focus among the ports: Manual - which involves pressing the push button port selection switches located on the unit's front panel; and Hotkey - which involves entering combinations from the keyboard.
