Dominion KX 1.4
Frequently asked questions 6/9
Some operating systems
“lock up” if you disconnect
a keyboard or mouse during
operation. What prevents
servers connected to
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 Dominion KX?
Servers connected to Dominion KX do not require any software agents
to be installed, because Dominion KX connects directly via hardware to
servers’ keyboard, video, and mouse ports.
How many servers
can be connected
to each Dominion KX unit?
Dominion KX models range, offering 16 or 32 server ports in a 1U
chassis or 64 server ports in a 2U chassis. This is the industry’s highest
digital KVM switch port density.
What happens if I disconnect
a server from Dominion KX
and reconnect it to another
Dominion KX unit, or connect
it to a different port on the
same Dominion KX unit?
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 CommandCenter
®
Secure Gateway management
appliance.
How do I connect a serially
controlled (RS-232) device
to 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 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 line of secure console
servers. For multiple serial devices, Dominion SX offers more serial
functionality at a better price point than Dominion KX. This SX is 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.
Local Port
Can I access my servers
directly from the rack?
Yes, at the rack Dominion KX functions just like a traditional KVM switch
– allowing you to control up to 64 servers using a single keyboard,
mouse, and monitor.
How do I select between
servers while using the
local port?
Is there an On-Screen
Display (OSD)?
Yes. Dominion KX’s local access port displays an on-screen display
interface that presents a list of all servers connected to the Dominion KX
unit. Users interact with this convenient on-screen display interface to
select a connected server.
How do I ensure that only
authorized users can access
servers from the local port?
Users attempting to use the local port must pass the same level of
authentication as those accessing remotely. This means that:
If you have configured Dominion KX to interact with an external RADIUS,
LDAP, or Active Directory server, users attempting to access the local
port will authenticate against the same server.
If the external authentication servers are unavailable, Dominion KX fails-
over to its own internal authentication database.
Dominion KX has its own standalone authentication, enabling instant/
out-of-the-box installation.
