System Modes and LED Indicators
System Modes and Denitions
There are 7 system modes in Synology NAS. The System modes and their denitions are as below:
System mode Denition
Powering on Synology NAS is powering on and performing hardware initialization, such as
hardware reset or BIOS initialization.
Shutting down Synology NAS is shutting down as a result of pressing the power button or operation
in DSM.
DSM not ready
DSM is not ready for use. This could either be:
• Synology NAS is powered on, but DSM is not properly installed.
• Synology NAS is currently powering on and initializing services necessary for
DSM to fully function.
• The attached UPS device has insu󰀩cient power; DSM stops all services to
prevent data loss (enters safe mode).
DSM is ready for use DSM is fully functioning and users can sign in.
Hibernation Synology NAS has been idle for a while and is now in Hibernation mode.
Application
Certain packages/services (e.g., USB Copy and Find me service) while in operation
will control the actions of the LED. After the operation is complete, the LED indicator
will return to its normal state.
Powered o󰀨 Synology NAS is powered o󰀨.
Identify System Modes
You can identify the system mode through the POWER and STATUS LED indicators. Please refer to below table
for more details.

Transitions between System Modes
To better understand the transition between system modes, please refer to below examples:
• Powered on with no DSM installed:
Powered o󰀨 > Powering on > DSM not ready
• Powered on with DSM installed:
Powered o󰀨 > Powering on > DSM not ready > DSM is ready for use
• Enter hibernation then wake up from hibernation:
DSM is ready for use > Hibernation > DSM is ready for use
• Shutdown Synology NAS:
DSM is ready for use > Shutting down > Powered o󰀨
• Power failure with UPS attached:
DSM is ready for use > DSM not ready (due to power failure, DSM enters safe mode) > Shutting down >
Powered o󰀨 > Powering on (power has recovered, DSM will reboot)> DSM not ready > DSM is ready for use
