VI. Common Questions

Is it compatible with H41q/H51q? → Not compatible. Only for HIMax (X series); H41q/H51q use K series racks.

Does it support hot swapping? → The backplane is fixed, while card components support hot swapping (CPU, power supply, I/O).

Does it include bus cables? → Integrated backplane bus, no additional cables required.
