4 Operation
4.1 Front panel LED indicators
Special conditions for the LEDs
The locate command will make all lights blink on and off synchronously, before they
return to their normal functions as described above.
An FPGA firmware upgrade will activate running lights on the LEDs after the download
is finished. Do not remove power to the card when the running lights are active, the
card is busy unpacking and installing the new firmware. The FRS-HD-XMUX4 will
reboot automatically when finished.
4.2 GPI alarms
The FRS-HD-XMUX4 has one GPI output only. This is the status of the module, and it
follows the same logic as the Card Status LED described in the previous section.
