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.

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.

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.

Alarm Reset (JAR)

The system will notify you in the event

of a power supply failure. This feature

assumes that redundant power supply

units are installed in the chassis. Con-

nect 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.
