DAHDI 2.9.0 Upgrade Notes
*************************

These notes only apply to Digium TE133 or TE134 cards that are in firmware version 770017 or earlier.


.. 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 or TE134 cards::

   xivo-fetchfw install digium-te133
   xivo-fetchfw install digium-te134

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::
