  1. See the Lenovo ServerProven website for a list of the I/O modules that are compatible with the Flex System Enterprise Chassis.
  2. Do not mix different types of power supplies. Each chassis must contain either all ac-powered supplies or all dc-powered supplies.
    • For ac-powered chassis, do not mix 2100 W and 2500 W power supplies. Chassis powered by ac power should contain only power supplies of the same wattage.
    • For dc-powered chassis, do not mix 240 to 380 V dc and -48 to -60 V dc power supplies. Chassis powered by dc power should contain only power supplies of the same input voltage.
