Baseboard Specifications SAI2 Server Board TPS 6.2 Absolute Maximum Ratings Operation of the SAI2 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 50. 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 3.3-V Supply Voltage with Respect to ground -0.3 V to VDD + 0.3 V 2 -0.3 to +3.63 V 5-V Supply Voltage with Respect to ground -0.3 to +5.5 V Notes: 1. Chassis design must provide proper airflow to avoid exceeding Pentium® III maximum case temperature. 2. VDD means supply voltage for the device. 6.3 Calculated Power Consumption The following table shows the calculated power consumption for each of the power supply voltage rails for the SAI2 server board. These values were calculated using the specifications for the on-board components and processors. Assumptions for add-in card power and other peripherals powered from the server board are included in the table. Customers will need to modify the calculated power consumption numbers based on their anticipated usage - watts per PCI slot, etc. Note: The following numbers are provided as an example. Actual power consumption will vary depending on the exact SAI2 configuration. Refer to the appropriate system chassis document for more information. Table 51.
