 Half-duplex provides for communication in both directions, but
only one direction at a time (not simultaneously).
 Full-duplex allows communication in both directions
simultaneously.
Note: Occasionally there are problems running at 10 Mbps in either
half or full duplex. If you are experiencing problems, try another
speed and duplex setting.
See Network Speed Settings (on page 270) for more information.
3. Select the Enable Automatic Failover checkbox to allow the
Dominion KX II to automatically recover its network connection using
a second network port if the active network port fails.
Note: Because a failover port is not activated until after a failover has
actually occurred, Raritan recommends that you not monitor the port
or monitor it only after a failover occurs.
When this option is enabled, the following two fields are used:
 Ping Interval (seconds) - Ping interval determines how often the
Dominion KX II checks the status of the network connection
(setting this too low may cause excess network traffic). The
default ping interval is 30 seconds.
 Timeout (seconds) - Timeout determines how long a network port
must be “dead” before the switch is made. Both network ports
must be connected to the network. This option must be checked
in order for the Automatic Failover to function. The default
timeout is 60 seconds.
Note: The default ping interval and timeout causes remote sessions
to be dropped when the Dominion KX II device tries to switch over.
When this occurs, the remote session needs to be reestablished.
Reducing these intervals to much lower values will allow remote
sessions to stay connected, but will result in increased network
traffic.
4. Select the Bandwidth from the following options:
 100 Megabit
 10 Megabit
