3Rd Power Supply Fail Signal Enable/Disable; I C To Pci Enable/Disable - Supermicro Supero H8DA8-2 User Manual

3rd Power Supply Fail Signal
Enable/Disable
The system can notify you in the event
of a power supply failure. This feature
assumes that three redundant power
supply units are installed in the chas-
sis. If you only have one or two power
supplies installed, you should disable
the function with the J3P header to pre-
vent false alarms. See the table on the
right for jumper settings.

I C to PCI Enable/Disable
The JI 2 C1/2 pair of jumpers allows
you to connect the System Manage-
ment Bus to the PCI expansion slots.
The default setting is closed (on) for
both jumpers to enable the connec-
tion. Both connectors must be set the
2
same (JI C1 is for data and JI
the clock). See the table on right for
jumper settings.
Watch Dog
JWD controls Watch Dog, a system
monitor that takes action when a soft-
ware application freezes the system.
Jumping pins 1-2 will cause WD to
reset the system if an application is
hung up. Jumping pins 2-3 will gen-
erate a non-maskable interrupt signal
for the application that is hung up.
See the table on the right for jumper
settings. Watch Dog can also be
enabled via BIOS.
