SUPER MICRO Computer I2DMR-8G2 Acpi Features, Power Supply, CPU Overheat LED and Control

SUPER i2DMR-8G2/i2DMR-iG2 User's Manual

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning function in the BIOS. This allows the user to define an overheat tempera- ture. When this temperature is exceeded, fans will speed up, and the warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to 20A current and auto-sense voltage IDs ranging from 1.1V to 1.5V (*sup- ported by VRMs only). This will allow the regulator to run cooler and thus make the system more stable.

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing when the system is in the SoftOff state. Note that external modem ring-on can only be used with an SSI compliant power supply.

1-6 Power Supply

As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates.

The SUPER i2DMR-8G2/i2DMR-iG2 requires a 24-pin connector and two 4- pin 12V/15A connectors for CPU VRMs. Although most power supplies generally meet the specifications required by the CPU, some are inadequate. You should use one that will supply at least 500W of power, and an even higher wattage power supply is recommended for high-load configurations. Also your power supply must supply 2A for the Ethernet ports and the E8870 chipset.

It is strongly recommended that you use a high quality power supply that meets SSI EPS 12V 1U 500W PS Specification. To verify the status of SSI compliance, please visit the web site at http://www.ssiforum.org/. Addi- tionally, in areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recom-
