SUPER MICRO Computer X9DRD-iF Super I/O, Advanced Power Management, Management Engine ME

Chapter 1: Overview

to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.

1-7 Super I/O

The Super I/O supports two high-speed, 16550 compatible serial communication ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability, and a processor interrupt system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power manage- ment through an SMI or SCI function pin. It also features auto power management to reduce power consumption.

1-8 Advanced Power Management

The following advanced power management features are supported by this moth- erboard:

Intel® Intelligent Power Node Manager (NM) (Available when the NMView utility is installed in the system)

The Intel® Intelligent Power Node Manager (IPNM) provides your system with real-time thermal control and power management for maximum energy efficiency. Although IPNM Specification Version 1.5/2.0 is supported by the BMC (Baseboard Management Controller), your system must also have IPNM-compatible Manage- ment Engine (ME) firmware installed to use this feature.

Note: Support for IPNM Specification Version 1.5 or Vision 2.0 depends on the power supply used in the system.

Management Engine (ME)

The Management Engine, which is an ARC controller embedded in the PCH, pro- vides Server Platform Services (SPS) to your system. The services provided by SPS are different from those provided by the ME on client platforms.
