Maintenance Manual

Status Possible statuses for the master MCU
are:
■ Still starting up: the master MCU
is in the process of starting up.
Wait a few minutes and then
refresh the Status > Cluster
page.
■ OK: The master and slave are
communicating correctly.
■ Lost contact: The slave MCU has
lost contact with the master
MCU. This status will only be
momentarily visible because the
slave MCU will quickly restart
itself in this case.
If the slave MCU loses contact with the master MCU it will
restart itself. This is the only way that the slave MCU can be
correctly rejoined into the cluster. Usually, if a slave MCU has
lost contact with the master this is because the master has
itself restarted.
Last
seen
This field is only visible if the master has
not been seen for 11 seconds. The slave
MCU will automatically restart itself very
soon after it loses contact with the
master.
IP
address

MCU Port Matrix
The port provision of the various MCU models is shown in the table below. Each video port can be used by one video-
conferencing participant. Each audio-only port can be used by one voice-only participant in a video conference.
Where streaming and content ports are provided, when streaming and content ports are used up, video ports will not
be allocated to streaming viewers or providers of content; where streaming and content ports are not provided,
conferences with streaming viewers and conferences with content will use available video ports.
For the MCU 4500 and the MCU MSE 8510, the number and type of available media ports on the MCU is controlled by
the port capacity mode which you configure on the Settings > Media ports page.
Note: If port reservation is enabled, and if there are no dedicated content ports, then activating a conference's
content channel will cause that conference to consume one video port - even when content is not being delivered.
The MCU supports the following media port modes and capacities:
