Technical Reference • Back and front panel host-powered USB devices (other than keyboard and mouse) Load: continuous read/write activity on external drive/peripheral • LAN linked at 1000 Mb/s Load: continuous read/write benchmark on remote share • All on board peripherals enabled (serial, parallel, audio, ...) Table 26. Maximum Load Configuration Current and Power Results Output Voltage 3.3 V 5 V 12 V -12 V 5 VSB Maximum Load 5 A 7.83 A 2.34 A 0.1 A 0.68 A 2.8 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Telcordia SR-332, Method I Case 1 50% electrical stress, 55 ºC ambient. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF data was calculated from predicted data at 55 ºC. The Intel Desktop Board D2700DC has an MTBF of at least 394,528 hours. 2.9 Environmental Table 27 lists the environmental specifications for the board. Table 27.
