The following ports, used for communications to/from Network Time Protocol servers, are
open by default on all Kaleido systems:
Network Considerations for a Multiviewer Cluster
• If you change the system name or IP address of a cluster member while another cluster
member is offline or otherwise unavailable, the cluster’s integrity will be broken. If you
attempt to make such a change, XEdit will alert you of the situation, prompting you to
cancel the operation and try again later, when all cluster members are available.
However, in the advent that such a change was made by mistake, or that it as been
forced for some reason, you will have to repair the broken cluster (see “Repairing a
Cluster System” in the Kaleido Software User’s Manual).
• Changing the system name or IP address of a KMV-3901/3911 multiviewer associated
with a cluster, by using the card’s control panel on the Densité housing frame, or by
using the KMV-3901/3911 control panel in iControl, is not supported.
• To maintain the integrity of a cluster configuration, such changes must be made by
using the system configuration features available in XAdmin.
