Delete Files; Perform A Factory Restore On The Realpresence Touch - Polycom realpresence group series Administrator's Manual

If you prefer, you can have the system prepare the SD card by rewriting the data with zeroes and
reformatting the card, thereby eliminating any traces of old data. Be aware that this step adds about 20
minutes to the beginning of the factory restore process, when all you will see is a blank screen. You will
notice, however, that the LED indicator shows a fast blink of blue and amber lights during this process. The
lights blink normally during the rest of the restore process.
To reset the system to its factory partition software using a USB device:
1 Copy the build package (.tar file) and the sw_keys.txt file to the root directory of a USB device.
2 (Optional) Create a text file named zeroize.txt on the root directory of the USB device, then edit
the file by entering the word TRUE in all capital letters.
If the zeroize.txt file contains the word FALSE, or if the file is not in the root directory of the USB
device, the system uses the standard method of erasing data from the SD card.
3 Power down the system and plug the USB device into your system.
4 While holding the restore button, press the power button once.
5 Keep holding the restore button for 10 more seconds, then release it.
The software version of the update file on the USB device is displayed in the web interface.
6 Click Start Update to begin the factory restore.
After the SD card is prepared, the system displays the Polycom startup screen and the usual software
update screens on HDMI monitors. Other types of monitors will be blank. Do not power off the system during
the factory restore process. The system restarts automatically when the process is complete.

Delete Files

You can remove customer data and configuration information from the system for security purposes.
To perform a logical delete of the system files:
1 Power off the systems by holding down the Power sensor for 3 to 5 seconds. Unplug all network
connections.
2 Perform a factory restore.
3 Wait for the system to start up and display the setup wizard.
4 Power off the system.

Perform a Factory Restore on the RealPresence Touch

If the RealPresence Touch device is not functioning correctly or you have forgotten the Administration
password, you can use the factory restore button to reset the device. This operation completely erases the
RealPresence Touch device's settings and reinstalls the software.
