The KV1403A is a CX Series Server Access Module, VGA, USB with Audio. Place the server up to 164 feet (50 m) away using the ServSwitch CX 4-User, or up to 32 feet (10 m) away using the ServSwitch CX Uno. The "Keep alive" feature powers the module even if the switch loses power, and it's flash upgradable.
Order one unit for each server-to-switch connection, and use CATx cable to connect the Server Access Module (SAM) to the CX server port.
