Intel Recommendation for SDS2 rubber bumper installation, Revision 117 Order Number A85874-002

Intel® Server Board SDS2		Errata Listing
Implication:	The SDS2 system BIOS will enter the PXE boot sequence if various numeric
	keys are pressed during POST.
Workaround:	Do not enter numeric keys during the POST process.
Status:	Fixed. This issue is fixed in SDS2 BIOS Production Release 2.5 (Build 48) and
	later versions.

19.SDS2 board level operating temperature and power supply voltage tolerance modification

Problem:	In Table 73 of the Intel® Server Board SDS2 Technical Product Specification
	(TPS) Rev. 1.0, the board level operating temperature is specified as 0°C to
	55°C. In Table 75 of the SDS2 TPS Rev. 1.0, the power supply tolerance is
	specified as ±5% for the 3.3V rail. Intel has induced a failure condition during
	board level temperature and voltage margin testing at 55°C and ±5% voltage on
	the 3.3V rail in SDS2 Server Boards configured with PCI adapters in the
	64bit/66MHz PCI slots under extreme workloads during final validation testing.
	As a result, the SDS2 Server Board board level operating temperature
	specification has been modified to 0°C to 45°C, and the power supply tolerance
	specification for the 3.3V rail has been modified to ±3%. The SDS2 Server
	Board passes board level temperature and voltage margin testing performed
	according to these modified specifications.
Implication:	The SDS2 Server Board’s operating environment should be maintained within
	the modified board level operating temperature specification of 0°C to 45°C and
	the modified power supply tolerance specification of ±3% for the 3.3V rail. The
	power supply tolerance specification for the 5V, 12V, and 5V standby rails is still
	±5%. The system level operating temperature specification of the Intel® Server
	Board SDS2 integrated into the Intel® SC5100 Server Chassis is still 0°C to
	35°C. The Intel SC5100 Server Chassis’ cooling system is capable of
	maintaining a SDS2 board level temperature below 45°C at a 35°C system
	ambient temperature.
Workaround:	None.
Status:	Fix. Intel has identified a fix for this issue, which will be incorporated in the
	SDS2 FAB 5 server board.

20.Recommendation for SDS2 rubber bumper installation

Problem:	A rubber bumper is included with the Intel® Server Board SDS2. Intel
	recommends installing this bumper on the chassis before integrating the board
	into the chassis, in order to improve the board’s tolerance to vibration that may
	occur during shipment of the integrated system product.
