Power Management; Environment - Advantech SOM-5899 User Manual

Note! If system COMS is cleared, Advantech strongly suggests going to the
BIOS setup menu and loading default settings at the first boot up.
1.3.9

Power Management

1.3.9.1 Power Supply
Supports both ATX and AT power modes. VSB is for suspended power and can be
optional if not required by standby (suspend-to-RAM) support. RTC Battery may be
optional if keep time/date is not required.
1.3.9.2 PWROK
Power OK from the main power supply. A high value indicates the power level is
good. This signal can be used to hold off Module startup to allow Carrier-based
FPGAs or other configurable devices time to be programmed.
1.3.9.3 Power Sequence
According to PICMG COM Express COM.0 R 3.0 specification
1.3.9.4 Wake Event
Various wake-up events supports allowing users to apply different scenarios.
 Wake-on-LAN(WOL): Wake to S0 from S3/S4/S5
 USB Wake: Wake to S0 from S3
 PCIe Device Wake: depends on user inquiry and may need customized BIOS
 LPC Wake: depends on user inquiry and may need customized BIOS
1.3.9.5 Advantech S ECO Mode (Deep Sleep Mode)
Advantech iManager provides additional features allowing the system to enter very
low suspended power mode – S5 ECO mode. In this mode, the module will cut all
power, including suspended and active power into the chipset, and keep an on-mod-
ule controller active. Only under 50mW power will consume power, meaning user
battery packs can last longer. While this mode is enabled in the BIOS, system (or
module) only allows a power button to boot rather than others such as WOL.
