Question Answer
Some operating systems
“lock up” if you
disconnect a keyboard
or mouse during
operation. What
prevents servers
connected to the
Dominion KX from
“locking up” when users
switch away from them? Each Dominion computer interface module (DCIM) dongle acts
as a virtual keyboard and mouse to the server to which it is
connected. This technology is called KME (keyboard/mouse
emulation). Raritan's KME technology is data center grade,
battle-tested, and far more reliable than that found in lower end
KVM switches: it incorporates more than 15-years of experience,
has been deployed to millions of servers worldwide.
Are there any agents
that must be installed on
servers connected to the
Dominion KX? Servers connected to the Dominion KX do not require any
software agents to be installed, because the Dominion KX
connects directly via hardware to servers' keyboard, video, and
mouse ports.
How many servers can
be connected to each
Dominion KX unit? The Dominion KX models range, offering up to 32 server ports
per 1U sized unit and 64 server ports in a 2U sized unit; this is the
industry's highest digital KVM switch port density.
What happens if I
disconnect a server from
the Dominion KX and
reconnect it to another
Dominion KX unit, or
connect it to a different
port on the same
Dominion KX unit? The Dominion KX will automatically update the server port
names when servers are moved from port to port. Furthermore,
this automatic update does not just affect the local access port,
but it propagates to all remote clients and the optional CC-SG
management device.
How do I connect a
serially controlled (RS-
232) device to the
Dominion KX, such as a
Cisco router/switch or a
headless Sun server? If you only have a few serially-controlled devices, you may
connect them to the Dominion KX using Raritan's serial
computer interface module (CIM), Raritan AUATC.
However, if you have four or more serially controlled devices, we
recommend the use of Raritan's Dominion SX model line of
secure console servers. For multiple serial devices, Dominion SX
offers more functionality at a better price point than the
Dominion KX, while being just as easy to use, configure and
manage, and can be completely integrated with your Dominion
Series deployment. In particular, many UNIX and networking
administrators appreciate the ability to directly SSH to a
Dominion SX unit (which the Dominion KX, a digital KVM
switch, does not offer).
