84 DOMINION KX USER GUIDE
QUESTION ANSWER
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.
Note that, of course, 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) Whent 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.
