Monitoring LEDs
Each monitoring LED is green when lit, unless specified otherwise.
The PPC LED monitors the communication systems processor and the FPGA LED
monitors the dedicated video/graphics processor.

Module Status LED
The general module status LED, CD8 at the corner of the module monitors a variety of key
systems and lights up if an error is detected. See Figure 4-1 on page 47 for the location of the
LED, and Table 4-2 for a description of the LED colors.
If the card or module status LED, CD8, is flashing red, contact your Customer Service
