Port ID Numbering
Each KVM port section on the GCS1953 switch is assigned a port number (1 to 4). The port
numbers are marked (CPU 1, CPU 2, and CPU 3) on the rear panel of the switch (see page
11 for details).
The Port ID of a computer is derived from the KVM port number it is connected to. For
example, a computer connected to KVM port 2 has a Port ID of 2.
The Port ID is used to specify which computer gets the KVM, USB peripheral, and audio
focus with the Hotkey port selection method (see page 20 for details).
