With its advanced security features, the KVM Over the NET
TM
switch provides
the fastest, most reliable, most cost effective way to remotely access and
manage widely distributed multiple computer installations.
KVM Over the NET
TM
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 remote 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/2140v/4124v/4140v models have support for four temperature
sensors that can control up to six fans. The sensors regulate the fans to run at
optimum speed depending on the server room temperature, throttling down
when necessary, using energy more efficiently and prolonging the life of both
the fans and the switch.
The KN2124v/2140v/4124v/4140v models are audio enabled. On the local
unit, speakers and a microphone are supported; while remote units offer
support for speakers only.
