14 Intel Server Board SE7500WV2 Product Guide
ACPI
The SE7500WV2 supports the Advanced Configuration and Power Interface (ACPI) as defined by
the ACPI 2.0 specification. An ACPI aware operating system can put the system into a state where
the hard drives spin down, the system fans stop, and all processing is halted. However, the power
supply will still be on and the processors will still be dissipating some power, so the power supply
fans will still run.
The SE7500WV2 supports sleep states s0, s1, s4, and s5:
s0: Normal running state.
s1: Processor sleep state. No context will be lost in this state and the processor caches will
maintain coherency.
s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing the
power button or other wakeup event will restore the system state from the disk and resume
normal operation. This assumes that no hardware changes have been made to the system while
it was off.
s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No
context is saved by the OS or hardware.
CAUTION
The system is off only when the AC power cord is disconnected.
System Management
Intel integrates system management features into the hardware and provides additional features
through Intel® Server Management software. This section describes the integrated hardware
features, Intel Server Management software, and the System Setup Utility and FRU/SDR Load
Utility used to configure the hardware features.

Baseboard Management Controller

Intel server boards incorporate a baseboard management controller (BMC), which is a dedicated
microcontroller for system management activities. The BMC performs the following functions:
Monitors system components and sensors, including processors, memory, fans, power supplies,
temperature sensors, and chassis intrusion sensors.
Manages nonvolatile storage for the system event log (SEL), sensor data records (SDRs), and
baseboard field-replaceable unit (FRU) inventory.
Interfaces with the emergency management port (EMP) and LAN1 port to send alerts and
interact with remote management systems.
Provides the main front panel control functions (power on/off, reset, and so on).
