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 the system was reset will be active after the system was
reset.
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.
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 needed 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 EHX configuration software controls
these lights.
In addition these lights will indicate if the following errors are
detected at startup:
NVRAM error
When the NVRAM is found to be corrupt at start up the config card
will output the string CHECK BATTERY.
Non matching slave firmware
The Eclipse HX system only supports master and slave backup
between two cards that are running the same version of firmware.
In the case when a non matching slave card firmware version is
detected the NON-MATCHING SLAVE_FIRMWARE message is
displayed by the master CPU card.
Hardware version verification
When an older, unsupported version of the MVX or E-QUE FPGA is
detected, the EQUE FPGA VERSION USUPPORTED message is
displayed by the master CPU card.
Note: The dot matrix lights will also display system information
when the ENG button is pressed on the master CPU card. This is
described below in the section on the ENG button.
Status lights
OK Light
When flashing, the OK light indicates that the CPU card is
successfully communicating with the EHX configuration software.
