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
support.polycom.com
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
on page 7 and to "Configuring the System to Use Certificates"
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.
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.
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.
