Full Reset button
When a full reset is performed, all cards in the matrix reset, regardless of any
system preferences in the program software. Non-volatile memory is cleared.
To perform a full reset:
1. Press and hold the CPU card’s lower RESET button (the Full reset
button).
2. Simultaneously press and release the CPU card’s upper RESET
button.
3. Continue holding the CPU card’s lower RESET button for two seconds.
The CPU card then performs a full reset.
The same configuration that was active before the system was reset will be
active after reset.
When the cards and connected audio devices reset, they momentarily stop
their current activity and restart. During this process configuration information
is downloaded to the cards and audio devices from the CPU card’s non-
volatile RAM.
Note:
Under normal operating conditions it is not necessary to perform a full reset.
Technical personnel might perform a full reset if they believe that the CPU
card is operating incorrectly as a result of corruption of the microprocessor’s
internal data or instruction sequence.

5.5.1 Using the embedded configuration
In addition to the four EHX configurations that can be stored on the card, the CPU card also includes
an embedded configuration. The embedded configuration is designed for fast fault checking following
a system upgrade or field install (for example, checking hardware connections with user panels and
interface cards).
Note:
The embedded configuration may also be used as a back-up configuration, in the very rare event that
a system error renders the other configurations unusable.
