When the switch is closed, the D815EEA2 and D815EPEA2 boards reset and run the POST. 2. 8. 3. 3. 2 Hard Drive Activity LED Connector Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is being read from or written to a hard drive. For the LED to function properly, an IDE drive must be connected to the onboard IDE interface. The LED will also show activity for devices connected to the SCSI hard drive activity LED connector. For information about The SCSI hard drive activity LED connector Refer to Section 2. 8. 3. 2, page 79 80 Technical Reference 2. 8. 3. 3. 3 Power/Sleep/Message Waiting LED Connector Pins 2 and 4 can be connected to a single-colored or dual-colored LED. Table 50 shows the possible states for a dual-colored LED. Table 49.

LED State Off States for a Dual-Colored Power LED Description Power off Running Running/message waiting Sleeping Sleeping/message waiting Steady Green Blinking Green Steady Yellow Blinking Yellow NOTE To use the message waiting function, ACPI must be enabled in the operating system and a messagecapturing application must be invoked. 2. 8. 3. 3. 4 Power Switch Connector Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The switch must pull the SW_ON# pin to ground for at least 50 ms to signal the power supply to switch on or off. (The time requirement is due to internal debounce circuitry on the D815EEA2 and D815EPEA2 boards. ) At least two seconds must pass before the power supply will recognize another on/off signal. 81 Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 2. 9 Jumper Blocks CAUTION Do not move any jumpers with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Figure 17 shows the locations of the jumper blocks on the D815EEA2 and D815EPEA2 boards. 97531 A 10 642 J6B2 3 1 B J9G2 Present only on D815EEA2 boards OM11781 Item A B Description Front panel audio connector / jumper block BIOS Setup configuration jumper block Reference Designator J6B2 J9G2 Figure 17. Locations of the Jumper Blocks 2. 9. 1 · · Front Panel Audio Connector/Jumper Block With jumpers installed, the audio line out signals are routed to the back panel audio line out connector. With jumpers removed, the connector provides audio line out and mic in signals for front panel audio connectors. The connector at location J6B2 has two functions: Table 51 describes the two configurations of this connector/jumper block. CAUTION Do not place jumpers on this block in any configuration other than the one described in Table 51. Other jumper configurations are not supported and could damage the board. 82 Technical Reference Table 51. 9 5 Front Panel Audio Connector / Jumper Block (J6B2) Configuration Audio line out signals are routed to the back panel audio line out connector.

Table 52 describes the jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to configuration mode and the computer is powered-up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. Table 52. Normal 1-2 Configure 2-3 Recovery None BIOS Setup Configuration Jumper Settings (J9G2) Jumper Setting 3 1 Function/Mode Configuration The BIOS uses current configuration information and passwords for booting. A recovery diskette is required. 3 1 3 1 For information about How to access the BIOS Setup program The maintenance menu of the BIOS Setup program BIOS recovery Refer to Section 4. 1, page 111 Section 4. 2, page 112 Section 3. 7, page 106 83 Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 2. 10 Mechanical Considerations 2. 10. 1 Form Factor The D815EEA2 and D815EPEA2 boards are designed to fit into a standard ATX-form-factor chassis.
