Conferences are distributed between the MCUs in the cluster.
The loads on the MCUs depend on the number of conferences
running on each MCU and the sizes of those conferences.

All port licenses on slave blades are controlled by the master
blade. Depending on how you use the blades in the MSE
chassis, you might want to allocate all port licenses to the slot
that houses the master blade or you might distribute them
between the slots in the cluster. It does not matter to the cluster
how you have allocated the port licenses; in any case, the
master controls all port licenses and even if a blade has failed
in the cluster, the master will continue to have access to any
port licenses allocated to the failed blade's slot.

Displaying the cluster status on a slave MCU
This topic applies only to MCUs that are configured as part of a cluster.
To display cluster status, go to
Status > Cluster
.
The table below describes the
Status > Cluster
page that displays on a slave in a cluster. For information
about the details displayed on a master MCU, see

A slave MCU does not present the full MCU web interface. Some settings are only available on the master

The master MCU in a cluster inherits all the ports and port licenses from the slave MCU. Configure

When you look at the
