Delete Data and System Files

You can remove sensitive data and configuration information from the RealPresence Group Series
system for security purposes.
Procedure

sensor for 3 to 5 seconds.
2. Unplug all network connections.
3. Perform a factory restore.
4. Wait for the system to start up and display the setup wizard.
5. Power off the system.

Controlling the System Fan Speed

The Maximum Ventilation option reduces thermal stress to the power supply by increasing the fan speed
from 35% to 80%. This option is useful when the system is used in higher thermal areas, such as
enclosures with limited ventilation, 24/7 operations, hosting multipoint calls, and sharing content.
By default the option is on, resulting in an increase of the fan speed up to 80% duty cycle. But when the
option is not set to on, the fan runs at a lower speed, 35% duty cycle, reducing the fan speed and
increasing thermal stress on the power supply.
Note: The Maximum Ventilation option is not available on RealPresence Group Series 700 hardware
version 20 and above, 3x0, and 500 systems.

Configure the System Fan Speed

To set the fan speed for your system, you must use the Maximum Ventilation Option in the system web
interface.
The Maximum Ventilation option is not available on RealPresence Group Series 300, 500, and on
Polycom RealPresence Group 700 systems with a hardware version higher than or equal to 20.
