JL82599ES cannot find the device in the system

[tomhaha]

Hello: The PCB we designed uses JL82599ES to generate twoSFP+optical ports. We do not have an auxiliary power supply, and the input power supply is S0 +12V. The current problem is that the device cannot be found in the system. May I ask: In the absence of an auxiliarypower supply, must the power on timing of JL82599ES also be executedaccording to Figure 11-1 Power and Reset Sequencing in thespecification sheet? Can the MAIN_PW R_O K pin be directly pulled upto+3.3V without an auxiliary power supply? thank you!
