Clear Cmos (Jbt1); Pci Slot Smb Enable (Ji2C2/Ji2C3) - Supermicro X9SRW-F User Manual

X9SRW Motherboard Series User's Manual

Clear CMOS (JBT1)

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads
to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such
as a small screwdriver to touch both pads at the same time to short the connection.
Always remove the AC power cord from the system before clearing CMOS.
Note: For an ATX power supply, you must completely shut down the sys-
tem, remove the AC power cord and then short JBT1 to clear CMOS.

PCI Slot SMB Enable (JI2C2/JI2C3)

Use Jumpers JI2C2/JI2C3 to enable PCI
SMB (System Management Bus) support
to improve system management for the
PCI slots. See the table on the right for
jumper settings.
