3-3 CHASSIS PLANS
Legacy Non-ACPI Connection
For system integrators that either do not have or do not require an ACPI compliant power supply as
described in the section above, an alternative electrical configuration is described in the table on the
following page.
Signal Description Source
+12 DC voltage for those systems that require it Power Supply
+5V DC voltage for those systems that require it Power Supply
+3.3V DC voltage for those systems that require it Power Supply
+5VSB Not Required Power Supply
PWRGD Not Required Power Supply
PSON# Power Supply On. This signal is used to turn on an
ATX or EPS type power supply. If an ATX or EPS
power supply is used in this legacy configuration, a
shunt must be installed on the backplane from
PSON# to signal Ground. This forces the power
supply DC outputs on whenever AC to the power
supply is active.
Backplane
PWRBT# Not Used
In addition to these connections, there is usually a switch controlling AC power input to the power supply.
When using the legacy electrical configuration, the SHB BIOS Power Supply Shutoff setting should be set
to
Manual shutdown
. Refer to the
General ACPI Configuration
section of the
Advanced Setup
chapter in
this manual for details.
