All other error status indications generally indicate a more serious problem, and are
likely to be accompanied by considerable system malfunction. If an error indication
does not appear to affect system operation, save the database to DB0.DEF
immediately. For further details, see Chapter 4.3 of the Coral Control Cards
Installation Manual. When the system can be restarted without disrupting service,
press the reset pushbutton on the front panel of the MEX-IP2.

The Software Authorization Unit (SAU) cannot be detected at
the SAU port on the front panel of the MEX-IP2. Generally, this
indicates that:
The device is no longer present or is not securely fastened
to the MEX-IP2.
There is a mismatch between the number of the SAU device
installed on the card and the number of the SAU key.
CAUTION
If the SAU is removed from the MEX-IP2, the Coral system
automatically ceases call processing after 14 days. Relevant
messages appear on the PI, warning that the system will not
operate without the proper SAU.
See Chapter 5 of the Coral Control Cards Installation Manual.
