Updating Devices - AT&T Syn248 SB35010 Installation And Configuration Manual

Syn248 Installation and Configuration Guide

Updating Devices

New software versions improve system functionality. All Gateways and all Desksets
should be running the same software version number.
You can update all devices with one command, or you can update the Syn248 devices
individually.
We recommend automatic device software upgrades for installations with Internet
access. This allows your system to obtain the latest upgrade from our server. Automatic
upgrades may not work if your network's firewall prohibits connection to the AT&T
servers, or if you do not have DNS services provided by your ISP. If you need to manually
initiate updates, see
If Internet access is not available, see

Sometimes devices with different versions of software cannot detect each other
in the WebUI. Some versions of Syn248 software codes are incompatible, so that
when you use one device's IP address for logging on to the WebUI, only the
devices with compatible code versions appear in the device lists. For this reason,
if you are updating devices individually, wait until all other devices are updated
before updating the software version of the device whose IP address was used
for logging on to the WebUI. When an updated device restarts with new
software, it may disappear from the device list.
If a PC is connected to the Deskset PC port, restarting the Deskset causes the
PC to lose its network connection briefly.
Adding a New Deskset to an Existing System
When you add a new Deskset to an existing Syn248 system, it may require a software
upgrade in order to enable the latest Syn248 system features. In this case, the Deskset
will prompt you to upgrade its software.
The first release of Syn248 included SB35020 Desksets running software version 1.0.0. If
you add Deskset models SB35025 or SB35031 to your system, you should upgrade the
software to take advantage of the new Deskset features. Syn248 software version 1.3.1
and higher for the SB35031 and SB35025 Desksets includes enhanced SB35025 Deskset
features such as Music on Hold and Overhead Paging.

Although unlikely, some types of software upgrades could interfere with
system settings and directories. Therefore, back up the system settings and
Deskset settings before updating the system software. If you receive automatic
updates, back up each device after each configuration change. See

The device restarts after a software upgrade. Ensure that there are no calls in
progress or they will be dropped.
