2.11.2 Add-in Board Considerations
The D815EEA2 and D815EPEA2 boards are designed to provide 2 A (average) of +5 V current for
each add-in board. The total +5 V current draw for add-in boards in a fully-loaded D815EEA2 and
D815EPEA2 boards (all six expansion slots filled) must not exceed 12 A.
2.11.3 Standby Current Requirements
CAUTION
Power supplies used with the board must provide enough standby current to support the Instantly
Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple
wake events from the PCI and/or USB buses exceeds power supply capacity, the board may lose
register settings stored in memory and may not awaken properly.
To estimate the standby current required for a specific system configuration, the standby current
requirements of all installed components must be combined. Refer to Table 55 and follow these
steps:
1. List the board’s +5 V standby current requirement (810 mA).
2. List the PS/2 ports’ standby current requirement (see note below).
3. List, from the AGP and PCI 2.2 slots (wake-enabled devices) row, the total number of wake-
enabled devices installed and multiply by the standby current requirement.
4. List, from the AGP and PCI 2.2 slots (non-wake-enabled devices) row, the total number of
wake-enabled devices installed and multiply by the standby current requirement.
5. List all additional wake-enabled devices’ and non-wake-enabled devices’ standby current
requirements as applicable.
6. Add all the listed standby current totals from steps 1 through 5 to determine the total estimated
standby current power supply requirement.
