What are the Memory Information and Procedures of the E8404A ?

Date: 04-13-2018

Memory Type: Static RAM	Memory Size: 512K x 16
Memory Function: This memory is on the E8401-66503 board which is the Enhanced Monitor for the E8404A. It provides display of the E8404A power supply (Voltages, Currents, Power), Slot temperature, and Fan Speed. This memory contains the most recent values of these parameters This is the operating system RAM for the main processor
User Modifiable (Y/N): Y	Volatile (Y/N): Y
Memory Erase Processes: Power cycle the product (i.e. turn OFF and then turn back ON)

Memory Type: Static RAM	Memory Size: 64K x 16
Memory Function: This memory is on the E8401-66503 board which is the Enhanced Monitor for the E8404A. This ram is used by a dedicated LCD Controller to drive the LCD display
User Modifiable (Y/N): Y	Volatile (Y/N): Y
Memory Erase Processes: Power cycle the product (i.e. turn OFF and then turn back ON)

Memory Type: Battery backed Static RAM	Memory Size: 8K x 8
Memory Function: Stores calibration for the monitor and a history of the E8404A power supply (Voltages, Currents, Power), Slot temperature, and Fan Speed.
User Modifiable (Y/N): Y	Volatile (Y/N): N
Memory Erase Processes: To clear the history send the commands: HISTORY:RESET:ALL;:SYST:NVDEFAULT;:SYST:SAVE To clear the calibration and the Critical System info do: DIAG:BIRTH ,<year>,<month>,<day> i.e. DIAG:BIRTH 2004,3,1 set to March 1, 2004 The DIAG:BIRTH command is not in the users manual. After doing the DIAG:BIRTH command a re-calibration is required.

X Sanitization process is documented above
• Sanitization process could be available with engineering resources
• Sanitization process is not possible (i.e. sanitize the product by destruction)
