3.2.2.2
Tree View
The tree view selector allow you to navigate to the right signal you need by unfolding the desired machine /
signal set and finally the right signal. Then click on the configuration wheel to do the settings.
Selection of multiple ports of the same category is also supported.
Note that on Firmware’s > 2.10 quick enable/disable switch were added next to the configuration wheel
allowing fast enable / disable of ports without renaming it neither changing standard. Additionally if the signal
is actually used in the grid a small crosspoint icon is also displayed as a warning against undesired disable
action.
3.2.3 Machine status
On Firmware’s > 2.10 the selected node technical status is displayed at the bottom of the graph page.
This enhanced reprint of the display screen allows user to know the detailed condition of this node.
3.2.3.1
Status / Signals presence
On the left side general status and the signal presence are displayed as on the visualization screen.
Optional parts like extra RS422 and Trunks are masked or grayed if not present in the machine
3.2.3.2
Node condition
On the right side the node technical condition is displayed as follows:
•
Main components temperature,
•
Main power supplies,
•
Fan currents,
•
Optical power received on trunks.
Nominally all values are displayed in Green. If value start to be out of tolerance, value turn to Orange and if
it is totally out of tolerance display turns Red.
Note on thermal management: with normal airflow Fpga and Motherboard Temperature are similar. If Airflow
is obstructed, FPGA will become hotter at high operating temperatures. A protective thermal shutdown is
operated when FPGA temperature is over 95°C in order to protect silicon with a good safety margin. Power
cycle is needed to restart the internal PSU section after unit self-cooling (The fans are still running after
thermal shutdown allowing fast cool down when fresh air is allowed again to flow thru the unit).
