Software Authorization Unit (SAU)

The MEX-IP2 supervises the feature authorization using the SAU (Software
Authorization Unit) lock device. The SAU is a small, encapsulated device which is
plugged into a component side connector on the MEX-IP2.
The SAU enables a set of permissions and feature authorizations associated with its
unique identification number. The Coral software detects and verifies the permission
settings of the SAU on the Control card (MEX-IP2) enabling the system to function
properly.
Replacing an MEX-IP2 card necessitates removing the SAU from the old card and
installing it on the replaced MEX-IP2 card.
When starting up the Coral system, ensure that there are no SAU Fault
messages during start-up or SAU Alarms (PI Branch: Root, 1, 1,
15-Controls) due to any one of the following three reasons:
-- a missing SAU device
-- inappropriate SAU software for this type of system
-- mismatched SAU serial numbers on the IMC8/16 and SAU device
For further details, see Chapter 5 of the Control Card Installation Manual .
