Sds2 Board Level Operating Temperature And Power Supply Voltage Tolerance Modification; Recommendation For Sds2 Rubber Bumper Installation - Intel SDS2 Specification

Intel® Server Board SDS2
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.

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.
