The switches feature RJ-45 connectors allowing them to use CAT 5e cable to
link to the servers. This space-saving innovation means that a full 24/40-port
switch can be conveniently installed in a 1U system rack, and the installation
can take advantage of the internal network wiring built into most modern
commercial buildings.
Setup is fast and easy; plugging cables into their appropriate ports is all that is
entailed. Because the switch intercepts keyboard input directly, there is no need
to get involved in complex software installation routines, or to be concerned
with incompatibility problems.
Since the firmware is upgradeable over the network, you can stay current with
the latest functionality improvements simply by downloading firmware
updates from our website as they become available.
With its powerful security features, the KVM over IP switch provides the
fastest, most reliable, most cost effective way to remotely access and manage
widely distributed multiple server installations.
KVM over IP 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.
The KN2124VA / KN4124VA / KN2140VA / KN4140VA support advanced
virtual media functions that allow higher transmission speed and mapping of
USB DVD/CD/hard drives and other storage media directly to a server. Virtual
media support allows you to conduct file transfers, install 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 KN2124VA / KN4124VA / KN2140VA / KN4140VA offer 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, they guard
against power failure from your server room outlets. If your server room has
more than one power source, connecting the power supplies to different power
sources is a wise choice. If one of the server room power supplies loses power,
the switch will automatically adjust the power it draws from the second source
to keep functioning.
The KN2124VA / KN4124VA / KN2140VA / KN4140VA models support
temperature sensors that can control internal fans. The sensors regulate the fans
so that they run at optimum speed depending on the server room temperature –
