Port ID Numbering
Each CPU port on the GCS1742/GCS1744 switch is assigned a port number (1 or 2 for GCS1742; 1 to
4 for GCS1744). 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 it is connected to. 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 peripheral, and audio focus with the
Hotkey port selection method.
Port Switching
There are two ways to access the computers in your KVM setup:
• Manual switching – pressing the push-buttons on the unit’s front panel
• Hotkey switching – entering commands from the keyboard
