Maintenance Manual

Caution: Auto-refreshing pages keep web sessions alive indefinitely meaning that an administrator login will never
timeout. This may be considered to be a security weakness. Also, auto-refresh can impact performance on an MCU
that is otherwise heavily loaded, particularly if multiple users are auto-refreshing the web interface.
To control the auto-refreshing of status pages on the MCU:
1. Go to Settings > User interface.
2. Choose the time interval for page auto-refreshes or, to stop pages from auto-refreshing, choose No auto-
refresh (default).
The status pages affected by this control are as follows:
— Status > General
— Status > Health
— Status > Conferences
— Status > Cluster (Note that this page is only available on clustered MSE 8510 Media blades.
— Conferences > Conference name > Participants
— Conferences > Conference name > Statistics
— Conferences > Conference name > Participant > Statistics
— Conferences > Conference name > Participants > Content channel
3. Click Apply changes.
Controlling the Display of Thumbnail Preview Images
To control the display of thumbnail preview images on the MCU:
1. Go to Settings > User interface.
2. Choose whether you want to Show video thumbnail images or not. This controls whether or not you will see a
preview of what an endpoint sees in the conference and participants pages that can show a preview of the
conference. Note that thumbnail images will not be shown for conferences where encryption is required.
3. Click Apply changes.
Controlling the Confirmation of Participant Disconnections
The default settings for the MCU allow you to disconnect, without confirmation, individual participants from a
conference on the Conference list > Conference > Participants page. On the Settings > User interface page, you
can configure the MCU to display an "Are you sure?" confirmation box when attempting to disconnect an individual
participant. Note that all-participant disconnections always require confirmation.
To control the confirmation of individual-participant disconnections:
1. Go to Settings > User interface.
2. If you want attempted individual-participant disconnections to require confirmation, enable the Confirm
individual participant disconnections option and click Apply changes.
Toggling the Controls for Muting Audio and Stopping Video of Conference Participants
Using the default settings of the MCU, a conference's Conference list > Conference > Participants page displays
controls that allow the muting of a participant's audio and video channels. The Settings > User interface page allows
you to control the presence or absence of these controls:
1. Go to Settings > User interface.
2. For Participant list controls, select the control(s) that you want to appear on the Participant list page.
