• a: The upper one is an RJ45 serial port, and the lower one is an RJ45 management port.
• b: The BMC_SER_MANUAL pin is used for changing the connection direction of the physical serial port. The CLEAR_BMC_PW pin is used for restoring default iBMC settings.
• c: The built-in USB 3.0 port can be connected to the front USB 3.0 port through a USB cable. It cannot be used directly.
• d: CPUs 1 and 2 are on the mainboard, and CPUs 3 and 4 are on the daughter board. The mainboard and daughter board are interconnected through high-speed backplane connectors.
• e: The port is reserved.
