SUPER MICRO Computer X9SVL-IIF, X9SCM-IIF user manual Clear Cmos, PCI Slot SMB Enable

Chapter 2: Installation

Clear CMOS

Contact Pads

JBT1 is used to clear the CMOS memory. 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 system, remove the AC power cord and then short JBT1 to clear CMOS.

PCI Slot SMB Enable

Use Jumpers I2C1/I2C2 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.
