14th generation iDRAC9 release supports lockdown feature, also known as System Lockdown Mode. This feature provides a mechanism to protect configuration from any unintentional or accidental changes after the system is provisioned to a certain level. The lockdown mode is applicable to both system configuration and firmware updates.

When System Lockdown Mode is enabled, the system’s configuration is locked and system cannot be configured or updated until the lockdown mode is disabled. There are some exceptional configuration settings that are allowed even when System Lockdown Mode is enabled.

Exceptions are as follows:

 Power operations ( System power on, power off, reset)

 Power budget and power profiles

 Identify operations to blink an LED

 Run diagnostics
