Trigger if updating inserting
For details on the older CX5000 models head over to this older article.The same software release package is applicable to both the CX5100 and CX5500 models so there are no separate download files to worry about.If after inserting the USB drive the phone does not appear to recognize the firmware package and does not automatically prompt for the administrator password then an additional manual step may be required.The affected models should now successfully recognize the firmware file and trigger the update process.(Note that while the some VVX desktop phone models do include a standard USB port they do not currently support this USB upgrade method.) While most any USB flash drive should work for this process it is recommended to use a USB 2.0 drive.And because the firmware is only a few hundred megabytes then pretty much any available USB drive can be used.This article will also be updated over time to include the latest available release along with a documented history of all firmware releases pertinent to Lync and Skype for Business platforms.
If the Lync Base Profile is currently enabled on the Trio then the web management interface will be disabled by default.
Once the 5.4.0 Rev BB release has been applied to the phone then this manual step will no longer be required for future updates as the phone will now recognize the correct firmware file names automatically.
An earlier article entitled Polycom CX5100 for Lync 2013 introduced the newest Round Table device for Lync, briefly discussing the firmware update process.
While the Trio can be updated in all the same ways that VVX phones already support there is a new capability provided with the Trio: using the local USB port.
In fact this is a very similar process to what the CX5100/5500 also supports for firmware upgrading.The entire process after confirming the administrator password should take less than 10 minutes, so as long as the gear icon is still spinning do not reboot the phone, just wait for the eventual reboot.
