Firmware update
The firmware of the SIP Ring Switch is continuously being improved to meet the
constantly changing requirements of growing networks.
The current firmware for your SIP Ring Switch can be found on the respective Web
data sheet page at www.WuT.de/article number, e.g. www.wut.de/57753
To install the firmware update, you need a Windows PC with the WuTility tool
installed (included in the firmware archive) and unrestricted network access to the
SIP Ring Switch.
Start WuTility, highlight your SIP Ring Switch in the inventory list and click on
Firmware
in the icon bar. Select the corresponding UHD file. WuTility will guide you
through the update process.
Do not interrupt either power or the network connection during the update.
All the settings in the SIP Ring Switch are retained and the SIP Ring Switch should
be immediately ready to use following the update.
Emergency access
In case you have forgotten the passwords for the SIP Ring Switch or simply want
to reset the device to its factory defaults, there are model-dependent emergency
accesses. In any case, you need physical access to the device.
Delete passwords
Emergency access can be activated by a long press (time window 3 - 7 seconds, the
LEDs below the reset button flash slowly) of the recessed reset button. For about
5 minutes, an emergency page can be opened via the browser when the SIP Ring
Switchs IP address is called. Here all passwords can be deleted via a button.
Reset to factory settings
If the reset button is pressed for a long time (more than 7 seconds), the LEDs be-
low the button start to flash quickly. The delivery state is restored. After approx. 30
seconds, the reset button must then be pressed short again to restart the SIP Ring
Switch
