APPENDIX C: FAQS 85
QUESTION ANSWER
Can Dominion KX used
over the WAN
(Internet), or just over
the corporate LAN?
Yes. Whether via a fast corporate LAN, the less predictable WAN
(Internet), a cable modem, or dial-up modem, Dominion KX’s KVM
Over IP technology can accommodate your connection. Raritan’s IP-
Reach KVM Over IP technology is integrated into every Dominion KX
unit. Raritan pioneered configurable video compression technology,
leading the industry by years, as evidenced by its awards.
Can I use Dominion KX
with a VPN?
Yes. Dominion KX uses standard Internet Protocol (IP) technologies
from Layer 1 through Layer 4. Traffic can be easily tunneled through
any standard VPN.
How many TCP ports
must be open on my
firewall in order to
enable network access to
Dominion KX? Are
these ports configurable?
Only one. Dominion KX protects your network security by only
requiring access to a single TCP port to operate. This port is completely
configurable for additional security.
To utilize Dominion KX’s optional Web browser capability, the
standard HTTPS port 443 must also be open.
Does the secondary
network port provide
redundant fail-over, or
load balancing?
The secondary network port provides redundant fail-over capabilities:
should the primary Ethernet port (or the switch/router to which it is
connected) fail, Dominion KX will fail-over to the secondary network
port with the same IP address – ensuring that your server operations are
not disrupted. Note that Automatic Failover is disabled by default.
Does Dominion KX
require an external
authentication server to
operate?
No. Dominion KX is a completely self-sufficient appliance. After
assigning an IP address to Dominion KX, it is ready to use – with web
browser and authentication capabilities completely built-in.
Of course, should you desire to use an external authentication server
(such as LDAP, Active Directory, RADIUS, etc.), Dominion KX
allows you to, and will even fail-over to its own internal authentication
should your external authentication server become unavailable. In this
way, Dominion KX’s design philosophy is optimized to provide ease of
installation, complete independence from any external server, and
maximum flexibility.
Can Dominion KX be
used with CITRIX?
Dominion KX may work with remote access products like CITRIX if
configures appropriately, but Raritan cannot guarantee it will work with
acceptable performance. Customers should realize that products like
CITRIX utilize video redirection technologies similar in concept to
digital KVM switches so that two KVM over IP technologies are being
used simultaneously.
Can the Dominion KX
utilize DHCP?
DHCP addressing can be used, however, Raritan recommends fixed
addressing since the DKX is an infrastructure device and can be
accessed and administered more effectively with a fixed IP address.
I’m having problems
connecting to the
Dominion KX over my
IP network. What could
be the problem?
The Dominion KX relies on the customer’s LAN/WAN network. Some
possible problems include: 1) Ethernet AutoNegotiation. On some
networks 10/100 autonegotiation does not work properly and the KX
unit must be set to 100MB/full duplex or the appropriate choice for its
network. 2) Duplicate IP Address. If the IP Address of the KX is the
same as another device, network connectivity may be inconsistent. 3)
Port 5000 conflicts. If another device is using port 5000, the KX default
port must be changed (or the other device must be changed). 4) When
changing the IP Address of a KX or swapping in a new KX, sufficient
time must be allowed for the KX IP and MAC Addresses to be known
throughout the Layer 2 and Layer 3 networks.
