22 Description 23 MAXDATA PLATINUM 100 Server
Power Connector
When used with an ATX12V or EPS-12 V compliant power supply that supports remote
power on/off, the MAXDATA PLATINUM Server 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
CAUTION
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 dama e 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 PLATINUM Server 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 cap-
able of providing ad5 V standby current. Failure to provide adequate standby current
when implementing Instantly Available PC technology can damage the power supply.
The MAXDATA PLATINUM Server 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.
