KVM Over the NET

switches have an Adapter ID function that stores port
information like the adapter ID, OS, keyboard language, adapter name,
operation modes and more, so that when you move a KVM Adapter Cable from
one port to another, the switch recognizes the same adapter cable at the new
location. Also, for greater ease of use when moving the adapter cable to another
switch, the adapter ID, OS, keyboard language, adapter name, and operation
modes of the port stay with the adapter.
With its advanced virtual media features, the KN2124v / KN2140v / KN4124v
/ KN4140v series of switches let you map DVD/CD drives and other storage
media to a server. This function allows you to conduct file transfers, installs
applications and OS patches, and perform diagnostics remotely. You can
upgrade your entire installation from a single remote console located anywhere
in the world.
The KN4140v offers dual power supplies so that if one of the power supplies
fails, the second power supply automatically takes over. In addition to
supporting dual power, the KN4140v guards against power failure from your
server room outlets. If your server room has more than one power source,
connecting the KN4140v power supplies to different power sources is a wise
choice. If one of the server room power supplies loses power, the KN4140v
will automatically adjust the power it draws from the second source to keep
functioning.
The KN2124v, KN2140v, KN4124v, and KN4140v models support four
temperature sensors that can control up to six fans. The sensors regulate the
fans so that they run at optimum speed depending on the server room
temperature – throttling down when necessary, to use energy more efficiently
and prolong the life of both the fans and the switch.
The KN2124v, KN2140v, KN4124v, and KN4140v models are also audio
enabled. Microphone and speakers are supported on the Local Console for the
servers; speakers are supported on the remote users’ computers.
