 Autodetect (default option)

 10 Mbps/Half - Both LEDs blink

 10 Mbps/Full - Both LEDs blink

 100 Mbps/Half - Yellow LED blinks

 100 Mbps/Full - Yellow LED blinks

 1000 Mbps/Full (gigabit) - Green LED blinks

 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 289) for more information.

3. Select the Enable Automatic Failover checkbox to allow the KSX 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

KSX II checks the status of the network path to the designated
gateway. The default ping interval is 30 seconds.

 Timeout (seconds) - Timeout determines how long a designated

gateway remains unreachable via the network connection before
a fail over occurs.

Note: The ping interval and timeout can be configured to best meet
the local network conditions. The timeout should be set to allow for at
least two or more ping requests to be transmitted and responses
returned. For example, if a high rate of failover is observed due to
high network utilization, the timeout should be extended to 3 or 4
times the ping interval.

4. Select the Bandwidth.

5. Click OK to apply the LAN settings.
