The KH2516A KVM switch is a control unit that allows IT administrators to access and control multiple computers from two PS/2 or USB KVM consoles (one bus). Operators working at up to two consoles can independently and simultaneously take control of up to 16 computers. By daisy chaining up to 31 additional switches, as many as 512 computers can be controlled from the original KVM consoles.

This switch has been designed with unique and powerful features that enable administrators to manage their entire server room and data center devices easily and conveniently.
For example, the advanced Adapter ID feature stores the Adapter Cable's configuration information - such as its ID, port name, OS, keyboard language, etc. This feature allows administrators to relocate servers to different ports without having to reconfigure the adapters. Other advances found with these switches includes enhanced video quality - extending the distance to the servers to up to 50 m at a resolution of 1280 x 1024.*With KVM Adapter Cable KA7000 series

Question: Hello, I want to buy the Aten (model KH2516a). Is there a discounted kit price for including Aten USB KVM Adapter Cable (CPU Module) for the 16 total ports?
Answer: Thank you for your inquiry,

For greatest flexibility between applications, the Aten KH2516a KVM switch is sold separately from the KVM cables. That being said, please feel free to contact your KVM Switches Online sales representative directly for a bulk pricing quote.
