These processors have a core configuration of up to 8 cores and an Intel UHD Graphics Gen12 with up to 32 EUs.
  • Page 26 The A4SAN supports a wide range of 9 V to 36 V DC input power to meet various embedded system requirements, such as transportation and medical applications. Based on numerous demands from embedded applications, Supermicro developed an optimized thermal solution for A4SAN, producing a fanless design on a rugged embedded system.

  • Page 27: Special Features

    A4SAN-H/-E/-L/-WOHS: Introduction 1.3 Special Features Recovery from AC Power Loss The Basic I/O System (BIOS) provides a setting that determines how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must press the power switch to turn it back on), or for it to automatically return to the power-on state.

  • Page 28: System Health Monitoring

    A4SAN-H/-E/-L/-WOHS: Introduction 1.4 System Health Monitoring Onboard Voltage Monitors An onboard voltage monitor will continuously scan the voltages of the onboard chipset, memory, processor, and battery.
