23 MAXDATA Fusion 6000
Power Connector
When used with an ATX12V or EPS-12 V compliant power supply that supports remote
power on/off, the MAXDATA Fusion 6000 System board can turn off the system power
through software control. When the system BIOS receives the correct command from the
operating system, the BIOS turns off power to the computer.
With soft-off enabled, if power to the computer is interrupted by a power outage or a
disconnected power cord, when power resumes, the computer returns to the power state it
was in before power was interrupted (on or off). The computer’s response can be set using
the After Power Failure feature in the BIOS Setup program’s Boot menu.
Fan Connectors
Table 8 summarizes the function/operation of the fan connectors.
Table 8. Fan Connector Function/Operation
Connector Description
Processor fan (CPU
FAN)
• +12 V DC connection for a processor fan or active fan heat sink.
• 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 Hardware Management ASIC.
Front and rear chassis
fans (FAN1, FAN2,
and FAN3)
• +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 Hardware Management ASIC.
LAN Wake Capabilities
For LAN wake capabilities, the 5 V standby line for the power supply must be capable of
providing ad5 V standby current. Failure to provide adequate standby current when
implementing LAN wake capabilities can damage the power supply.
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 MAXDATA Fusion 6000 System board supports
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
Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power supply must be
capable of providing ad5 V standby current. Failure to provide adequate standby cur-
rent when implementing Instantly Available PC technology can damage the power supply.
The MAXDATA Fusion 6000 System board supports the PCI Bus Power Management
Interface Specification. Add-in Board that also support this specification can participate in
power management and can be used to wake the computer.
The use of Instantly Available PC technology requires operating system support and PCI 2.2
compliant add-in cards and drivers.
