Firmware Update
When first installing the base station, snom recommends updating to the latest firmware version.
Please go to www.snom.com to see if a new version is available and to download it.
You can either use the snom M series update server or download the files to your own server and
update the firmware from there.
Note: We recommend to always operate the base station and the connected wireless
devices with the same firmware version.
Although it is possible to update an active live system, we cannot guarantee its
uninterrupted functionality. We therefore recommend performing wireless updates
when the whole system is idle.
Considerations before updating
• On average, it takes 10 - 15 minutes to transmit the firmware file to the wireless devices, but it
could take up to 60 minutes depending on trac (voice trac has priority).
• Using a handset will pause the transfer process to it. It will continue once the handset is back in
idle mode.
• Once the firmware has been transferred, the actual update of each wireless device takes approx.
one minute.
• The M700 can update up to 10, the M300 up to 5 wireless devices at a time. If more devices are
registered with the base, they will be updated successively.
Note: The base station randomly selects the devices for firmware transfer. It is not
possible to assign priority to certain devices.
• Repeaters will start updating automatically when there are no ongoing calls, resulting in a service
interruption of approx. one minute.
• Multicell installations.
◦ The M700 will update all handsets in range, including devices registered on another base
station.
◦ When a user moves from within the range of one base station to another, the update will
continue as long as sucient update capacity is available.
◦ When a multicell installation is fully occupied with firmware transfers, handover/roaming will
fail, i.e., active calls may be lost.
◦ When an update is initiated on one base station, all base stations will perform an update.
Updating manually
Manual updates are perfomed in several steps: Downloading the update files for registered wireless
devices to the base station and transmitting them from the base station to the devices, updating the
base station, and updating the handsets by placing them in their chargers.
