SGPIO

The two headers labeled SGPIO1 and SGPIO2 are for SGPIO (Se- rial General Purpose Input/Output). SGPIO provides a bus between the SATA controller and the SAS drive backplane to provide SAS enclosure management functions. Connect the appropriate cables from the back- plane to the SGPIO1 and SGPIO2 headers to utilize SAS management functions on your system.

JLAN1/2 (Ethernet Ports)

Two Ethernet ports (designated JLAN1 and JLAN2) are located beside the VGA port on the I/O backplane. These ports accept RJ45 type cables.

Alarm Reset (JAR)

The system will notify you in the event of a power supply failure. This feature assumes that Supermicro redundant power supply units are installed in the chassis. Connect a microswitch to the JAR header to disable the power supply fail alarm. Note: this header is unused on the 6025B-3, which has only a single power supply module.

Keylock

The keyboard lock connector is desig- nated JK1. Utilizing this header allows you to inhibit any actions made on the keyboard, effectively "locking" it.
