Upgrade UC Software Using a USB Flash Drive

You can use a USB flash drive to upgrade the software on your Polycom Trio system.

Changes you make using a USB flash drive override the settings you configure using a centralized provisioning server (if applicable). When you remove the USB flash drive, the Polycom Trio system reverts to the provisioning server settings.

Note: Polycom Trio 8800 supports only File Allocation Table (FAT) file systems. Polycom recommends using FAT32.


  1. Do one of the following:
    • Format a blank USB 2.0 USB flash drive using FAT32.
    • Delete all files from a previously formatted USB flash drive.
  2. Download the UC Software from Polycom Support.
  3. Copy the configuration files you want to use to the root of the USB device.

    The minimum required configuration files must be copied to the drive:

    • Master configuration file: 000000000000.cfg.
    • Polycom Trio 8500: 3111-66700-001.sip.ld
    • Polycom Trio 8800: 3111-65290-001.sip.ld.
    • Polycom Trio Visual+: 3111-66420.001.sip.ld.
  4. Insert the USB flash drive into the Polycom Trio system or Polycom Trio Visual+ USB port.
  5. Enter the Administrator password.

    The system detects the flash drive and starts the update within 30 seconds. The mute keys' indicator lights begin to flash, indicating that the update has started.

    The system reboots several times during the update. The update is complete when the indicator lights stop flashing and the Home screen displays.
