Dell EMC PowerEdge R240 Statement of Volatility
Summary
Statement of volatility for the Dell EMC PowerEdge R240 rack server, providing detailed volatile and non-volatile memory component information including data write capabilities, write protection status, and clearing procedures. Non-volatile items include 256-byte PCH CMOS RAM (battery-backed, cleared via NVRAM_CLR jumper or coin cell removal for 30 seconds), 16-byte BIOS password storage, BIOS SPI Flash, iDRAC SPI Flash, and BMC EMMC. Volatile components include iDRAC DDR4 and system memory up t

Frequently Asked Questions
What defines volatile vs. non-volatile components?
Volatile components lose data when power is removed, while non-volatile components retain data even after power loss.
How do I clear the BIOS configuration settings manually?
Set the NVRAM_CLR jumper to clear BIOS configuration settings or use AC power off followed by removing and replacing the coin cell battery for 30 seconds.
Which memory areas cannot be cleared by the user, even with advanced utilities?
Users cannot clear the SPI Flash (BIOS_SPI1), iDRAC firmware, CPU Vcore registers, or the System CPLD FLASH memory.
Can I update and configure the iDRAC system's secure software parameters?
Yes, configuration changes can be made as part of an iDRAC update using a command set provided by iDRAC.
