a. What is the junction temperature of each FPGA in the system (one per card)? None should
exceed 100 C (red) in the GUI.
b. What is the measured temperature of the optical transceiver? Does it enter the yellow or red
zones in the GUI?
c. If excess temperature is an issue, better thermal management is required:
