Intel® Server Platform SR6850HW4 TPS

System Overview

The SCSI Backplane Board performs the tasks associated with hot-swapping of the hard disk drives and enclosure (chassis) monitoring and management, as specified in the SCSI Accessed Fault-Tolerant Enclosures (SAF-TE) Specification. The SAF-TE-specified features supported by the SCSI Backplane Board include, but are not limited to, the following:

ƒMonitoring the SCSI bus for enclosure services messages, and acting on them appropriately. Examples of such messages include: activate a drive fault indicator; power down a drive that has failed; and report backplane temperature.

ƒSAF-TE intelligent agent acts as proxy for "dumb" I2C devices (that have no bus mastering capability) during intrachassis communications.

The SCSI Backplane Board connects to the Server Board Set SE8500HW4 Mainboard, provides power, and signals to the front of the chassis. See Chapter 7 for a description of this board.

2.5.5Front Panel I/O Board

The Front Panel I/O Board mounts horizontally in the front left of the system and communicates with the SCSI Backplane Board. The board contains a video connector, three USB ports and an NMI button. See Chapter 8 for a description of this board.

2.5.6Front Panel Control Board

Two different front panel Control Boards are supported, the standard control panel and the Intel Local Control Panel (LCP). Both mount vertically into the chassis and connect to the Front Panel I/O Board via a cable. Each module houses the system operating buttons, LEDs and the Local Control Panel has an LCD. See Chapter 8 for a description of these boards.

2.5.7SATA-to-IDE Converter Board

The SATA-to-IDE Converter Board attaches to the optical drive carrier, receives the SATA signal from the Server Board Set SE8500HW4 Mainboard via a SATA cable, and converts it to IDE signals routed to the optical drive. See Chapter 9 for a description of this board.

2.5.8Intel® Management Module

The Intel Management Module (IMM) mounts onto the Server Board Set SE8500HW4 Mainboard and contains the Baseboard Management Controller (BMC) that provides server management support. There are two versions of the IMM, the Professional and Advanced. The Advanced module adds more support for remote management. The Server Platform SR6850HW4 will not boot without one of these modules installed. See the Intel Management Module Installation and User’s Guide or the Intel Management Module Technical Product Specification for a description of this part.
