4.12 System Management Interface Signals
Name
Type
Description
INTRUDER#
I
Intruder Detect:
This signal can be set to disable system if
box detected open. This signal’s status is readable, so it can be
used like a GPI if the Intruder Detection is not needed.
SML0DATA
I/OD
System Management Link 0 Data:
SMBus link to external
PHY. External pull-up is required.
SML0CLK
I/OD
System Management Link 0 Clock:
SMBus link to external
PHY. External pull-up is required.
SML0ALERT#
/
GPIO60 /
O OD
SMLink Alert 0:
Output of the integrated LAN controller to
external PHY. External pull-up resistor is required. This signal
can instead be used as a GPIO60.
SML1ALERT#
/
GPIO74
O OD
SMLink Alert 1:
Alert for the ME SMBus controller to
optional Embedded Controller or BMC. External pull-up
resistor is required.
This signal can instead be used as a GPIO74
SML1CLK /
GPIO58
I/OD
System Management Link 1 Clock:
SMBus link to optional
Embedded Controller or BMC. External pull-up resistor is
required.
SML1DATA /
GP75
I/OD
System Management Link 1 Data:
SMBus link to optional
Embedded Controller or BMC. External pull-up resistor is
required.
