ECLIPSE OMEGA MATRIX INSTRUCTION MANUAL

FAIL-SAFE OPERATION
The CPU card’s non-volatile memory stores all information about the current
operating configuration and the three additional configurations, allowing the
system to restore itself automatically after a power failure, after replacement of a
port card, or after replacement of a panel.
An Eclipse Omega system will operate with either one or two CPU cards. When
you install a second card, that card stores the four configurations in its RAM as a
backup to the main card. If the main card is removed or becomes
non-operational for any reason, the system will automatically switch to the
second card as backup.
CPU CARD LIGHTS AND CONTROLS
The following sections describe the CPU card’s status lights and controls, which
are illustrated in Figure 2-2.
Reset Button
Pressing the reset button causes the CPU card to stop its current activity and to
restart. The same configuration that was active before you reset the system will be
active after you reset it.
During the reset, configuration information reloads to the card’s operational
memory from its non-volatile memory and the card starts running again from
the beginning.
Note: The reset button is slightly recessed from the front panel to prevent it from
being accidentally pressed. You need a tool, such as a bent paper clip, to
press this button.
Power Supply Lights
+ 5-Volt Light
When lit, the “+5V” light indicates that the matrix’s +5-volt power supply is
actively supplying power to the CPU card.
+3.3-Volt Light
When lit, the “+3.3V” light indicates that the matrix’s +3.3-volt power supply is
actively supplying power to the CPU card.
Dot Matrix Lights
The rectangular array of lights just below the power-supply lights displays a
number (either 1, 2, 3, or 4) to indicate the currently selected configuration. The
Eclipse Configuration System (ECS) controls these lights.
