DAHDI 2.9.2 Upgrade Notes
*************************

These notes only apply to:

* Digium TE133/TE131 cards that are in firmware version 780017 or earlier
* Digium TE435/TE235 cards that are in firmware version e0017 or ealier

.. warning::

   The system will need to be power cycled after the upgrade. Your cards will not be usable until then.


After the upgrade
=================

First, you need to install the latest firmware for your TE133/TE131 or TE435/TE235 cards::

   xivo-fetchfw install digium-te133
   xivo-fetchfw install digium-te435

Then stop all the services and reload the DAHDI modules. Reloading the DAHDI module might take up to 30 seconds::

   wazo-service stop
   service dahdi stop
   service dahdi start

Following this manipulation, you should see something similar at the end of the :file:`/var/log/messages` file::
