The KH2508Aand KH2516AKVM switches are control units that allow 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 8 (KH2508A), or 16 (KH2516A), computers. By daisy
chaining up to 31 additional switches, as many as 512 computers can be controlled from the original KVM
consoles.
These switches have 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.
A KH2508Aor KH2516Ainstallation provides one of the best, and most economical, solutions ATEN offers to the
SMB market. There is no better way to save time, space, and money than with a KH2508Aor KH2516AKVM
switch.

new ATEN KVM Cable Adapter KA7000 series. Using the new adapter cables
with ID means it is not required to change cable configuration settings when

hot-swap port connections without having to reconfigure attributes.
