CPU card Reset button
When the CPU card is reset by pressing its reset button, the card’s non-volatile memory
reloads all configuration information to the card’s microprocessor. Resetting the card clears
any corruption of data in the card’s microprocessor. The card momentarily stops its current
activity and restarts. The same system configuration that was active before the card was
reset will be active after the reset.
The reset button is slightly recessed from the front panel to prevent it from being accidentally
pressed. A tool such as a bent paper clip is required to press this button.
CPU card Full Reset button
Press and hold the full-reset button and simultaneously press the reset button for the system
to perform a cold restart. All cards in the matrix reset regardless of any system preferences
in the program software. All audio devices connected to the cards, such as panels and
interfaces, reset as well.
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 port
cards and connected audio devices from the CPU card’s microprocessor.
The same system configuration that was active before the card was reset will be active after
the reset. The button must be pressed for more than two seconds for the reset to take effect.
Under normal operating conditions it is not necessary to perform a full reset. Technical
personnel might perform a full restart if they believe that the CPU card is operating
incorrectly as a result of corruption of the microproccessor’s internal data or instruction
sequence.
Example data issues
Problem: A port light on an analog port interface does not illuminate, although there is a
panel attached to that port.
Action 1: Check the panel and the wiring leading to it.
Action 2: Check the Frame Data light. If there is no indication of matrix communication to
this interface card while the other interface cards in the matrix are communicating, reset the
interface card.
Action 3: Replace the interface cards.
Action 4: Replace the panel.
