General Specifications Intel® SHG2 DP Server Board Technical Product Specification
Intel Order Number C11343-001 Revision 1.0

9. General Specifications
This chapter specifies the operational parameters and physical characteristics for the Intel
SHG2 server board.
This is a board-level specification only.
System specifications are beyond
the scope of this document.
9.1 Absolute Maximum Electrical and Thermal Ratings
Operation of the SHG2 server board at conditions, beyond those shown in the following table,
may cause permanent damage to the system (provided for stress testing only). Exposure to
absolute maximum rating conditions for extended periods may affect system reliability.
Table 59 lists the maximum component case temperatures for baseboard components that
could be sensitive to thermal changes. The operating temperature, current load, or operating
frequency could affect case temperatures. Maximum case temperatures are important when
considering proper airflow to cool the motherboard.
Table 59. Absolute Maximum Electrical and Thermal Specifications
Operating Temperature 5°C to +50°C
1
Storage Temperature -55°C to +150°C
Voltage on any signal with respect to ground -0.3V to V
dd
+ 0.3V
2
3.3V supply voltage with respect to ground -0.3 to +3.63V
5V supply voltage with respect to ground -0.3 to +5.5V
Notes:
1. Chassis design must provide proper airflow to avoid exceeding Intel®
Xeon™ IHS (integrated heat spreader) maximum case temperature.
2. V
DD
means supply voltage for the device.
Caution: An ambient temperature that exceeds the board’s maximum operating temperature by
5°C to 10°C might cause components to exceed their maximum case temperature. When
determining system compliance, considerations should be given for maximum rated ambient
temperatures.

Component Maximum Temperature
Intel® Xeon™ processor, rating to meet Flexible Motherboard
(FMB) guidelines.
78°C (thermal plate)
CMIC-LE 100°C (case)
CIOB-X2 100°C (case)
CSB5 100°C (case)
82550PM Ethernet Controller 85°C (case)
