The following table provides information on whether a system restart is required when firmware is updated for a particular
component:
NOTE: When multiple firmware updates are applied through out-of-band methods, the updates are ordered in the most
efficient possible manner to reduce unnecessary system restart.

* Indicates that though a system restart is not required, iDRAC must be restarted to apply the updates. iDRAC communication and
monitoring may temporarily be interrupted.
** When iDRAC is updated from version 1.30.30 or later, a system restart is not necessary. However, firmware versions of iDRAC
earlier than 1.30.30 require a system restart when applied by using the out-of-band interfaces.
NOTE: Configuration changes and firmware updates that are made within the operating system may not reflect properly
in the inventory until you perform a server restart.
When you check for updates, the version marked as
Available
does not always indicate that it is the latest version available. Before
you install the update, ensure that the version you choose to install is newer than the version currently installed. If you want to
control the version that iDRAC detects, create a custom repository using Dell Repository Manager (DRM) and configure iDRAC to
use that repository to check for updates.
