Upgrading and Downgrading your Polycom HDX System

When you upgrade your Polycom HDX system to version 2.7.3.1_J, the factory 

partition might also be automatically upgraded if it contains certain previous 

versions with known issues that have been corrected. If you later perform a 

factory restore, the system returns to version 2.7.3.1_J instead of the software 

version originally installed on the system.
After installing version 2.7.3.1_J, downgrading to an earlier UC APL-certified 

software version is not recommended. However, if you must install a previous 

software version, contact Polycom support at

Upgrading the Software in a Non-DHCP Environment

If you are installing the Polycom HDX system in a non-DHCP environment, 

you need to manually configure the LAN properties during the setup wizard. 

In the LAN properties screen, choose Enter IP Address Manually and 

continue through the next screens to finish configuring the LAN properties. 
If you need to configure the system to use certificates or to customize other 

settings, you must access the HDX system’s web interface using a computer 

located on the same network segment as the HDX system. For information 

about such usage, refer to 

Upgrading from Versions Earlier than 2.7.0_J

Polycom recommends that you upgrade from software versions earlier than 

2.7.0_J to 2.7.3.1_J by performing a USB software update, which is described in 

the Release Notes for Polycom HDX Systems, version 2.7.3.1_J. If you use the 
Software Update feature in the HDX system web interface, the features added 

or changed between these two releases could lead to unpredictable behavior.

Upgrading from Version 2.7.1_J or 2.7.3_J

To update your system software from version 2.7.1_J or 2.7.3_J to 2.7.3.1_J, you 

can use the Software Update feature in the Polycom HDX system web 

interface, which is described in the Release Notes for Polycom HDX Systems, 

version 2.7.3.1_J. 

Site policy might restrict the types of USB devices that can be used for software 
updates. Please consult your site administrator before performing the USB software 
update.
