Installation
• Switch off all computers
• Ensure that the cables are not close to any sources of electrical noise interference such as
fluorescent lights, HVAC systems or motors
• Ensure that the distance between any computer and the KVM switch does not exceed 33 ft.
Connect each computer to the KVM using a Server Interface Unit (SIU) and Cat5e patch
cable (for best results, use STP cables—N105 series). Figure 4 illustrates the connection
options.
