10. Electrical and Thermal Specifications
This section describes the electrical and thermal specifications required to integrate this board in
a system.
10.1 Absolute Maximum Ratings
Operation of the SDS2 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 81. Absolute Maximum Ratings
Operating Temperature 0°C to 55°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 -0.3V to 3.63V
5V Supply Voltage with respect to ground -0.3V to 5.5V
Notes:
1. Chassis design must provide proper airflow to avoid exceeding Intel® Pentium® III processor maximum
case temperature.
2. V
DD
means supply voltage for the device.
10.2 Power Consumption
The following table shows the power consumed on each supply line for a SDS2 Server Board
configured with the following manner.
• Two processors, each with 30 W max
• Four DIMMs total, two active (burst) and two standby
• Three PCI cards, two on 3.3 V and one on 5V
• Five fans total, two processor fans and three system fans
• Five SCSI HD with SCSI backplane
Note: The following numbers are provided as an example. Actual power consumption will vary
depending on the exact configuration, temperature, voltage level, etc. Refer to the appropriate
system chassis document for more information.
