Crosspoint Module
The crosspoint module contains 1 crosspoint IC arranged to make a complete crosspoint array.
These ICs are located under the large metal heat sink in the middle of the board. Surrounding
the crosspoint array are IO buffers, the board control processor, and power supplies.
Crosspoint Module LEDs
There are 4 voltage status LEDs on the left side of the board. The LEDs indicate the status of the
module’s voltage. The LEDs on the right side of the board indicate CPU function and may vary
with code versions. All LEDs must be lit for the module to operate properly. The absence of any
lit voltage LED indicates a failure of the module and the factory should be contacted.
The factory should be contacted if any fault LEDs are lit.
Note:
The number of LEDs may vary in de-populated systems.
