Intel® Server Platform SR6850HW4 TPS
System Overview
Revision 1.0
Intel order number D23151-001
13
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:
Monitoring 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.
SAF-TE intelligent agent acts as proxy for "dumb" I
2
C 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.
2.5.5
Front 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.
2.5.6
Front 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.
2.5.7
SATA-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.
2.5.8
Intel® 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
