Product Description 1.14.2.2 Fan Connectors Table 11 summarizes the function/operation of the fan connectors. Table 11. Fan Connector Function/Operation Connector Processor fan Front chassis fan Rear chassis fan Description • +12 V DC connection for a processor fan or active fan heatsink. • Fan is on in the S0 or S1 state. Fan is off when the system is off or in the S3, S4, or S5 state. • Wired to a fan tachometer input of the SMSC LPC47M142 I/O controller. • +12 V DC connection for a system or chassis fan. • Fan is on in the S0 or S1 state. Fan is off when the system is off or in the S3, S4, or S5 state. • Wired to a fan tachometer input of the SMSC LPC47M142 I/O controller. • +12 V DC connection for a system or chassis fan. • Fan is on in the S0 or S1 state. Fan is off when the system is off or in the S3, S4, or S5 state. For information about The location of the fan connectors The signal names of the fan connectors Refer to Figure 13, page 61 Section 2.8.2.3, page 61 1.14.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the 5-V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. Refer to Section 2.11.3 on page 83 for additional information. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet† frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the D845BG and D845PT boards support LAN wake capabilities with ACPI in the following ways: • the PCI bus PME# signal for PCI 2.2 compliant LAN designs • the onboard LAN subsystem • a CNR-based LAN subsystem 43
