Reference the definition of “Magic Packets*”. Once the 82575EA Gigabit Ethernet controller
receives a matching Magic Packet*, it will:
If the Assert PME On APM Wakeup (APMPME) bit is set in the Wake Up Control
Register (WUC):
Set the PME_Status bit in the Power Management Control / Status Register (PMCSR)
and issue a PM_PME message (in some cases, this may require to assert the WAKE#
signal first to resume power and clock to the PCI-Express* interface).
Store the first 128 bytes of the packet in the Wake Up Packet Memory (WUPM).
Set the Magic Packet Received bit in the Wake Up Status Register (WUS).
Set the packet length in the Wake Up Packet Length Register (WUPL).
The 82575EA Gigabit Ethernet controller will maintain the first Magic Packet* received in the
Wake Up Packet Memory (WUPM) until the driver writes a 1 to the Magic Packet* Received
MAG bit in the Wake Up Status Register (WUS). “APM Wakeup” is supported in all power states
and only disabled if a subsequent EEPROM read results in the APM Wake Up bit being cleared
or the software explicitly writes a 0 to the APM Wake Up (APM) bit of the WUC register.
The NIC maintenance port associated with the Intel
®
Remote Management Module 2 does not
support WOL.
There are no LAN devices on PCI32, therefore PME# is not utilized for Wake-On-LAN.
3.3.8 Secure Mode Operation
Since the BMC is not logically located between the power button and the chipset, additional
front panel lockout buffers must be used on the Intel® Server System S7000FC4UR in order to
support Secure Mode Operation. These lockout buffers allow the BMC to prevent the user from
powering off or resetting the system.
The BMC logs secure mode violation events into the SEL when secure mode is enabled and a
user presses front panel buttons that are in a protected state. Secure mode is cleared when the
following occurs:
AC power or system power is applied
System reset occurs
BMC reset occurs
