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

Note:
1 Please try to restart your Synology NAS or re-insert the drives, then run the HDD/SSD manufacturer's
diagnostic tool to check the health status of the drives. If you can sign in to DSM, please run the built-in
S.M.A.R.T. test to scan the drives. If the problem remains unresolved, please contact Synology Technical
Support for help.
2 If the ALERT LED continuously blinks orange, this indicates there are system errors such as fan failure,
system overheating, or volume degrade. Please sign in to DSM for detailed information.

abrupt changes in temperature or humidity.
Place the unit right side up at all times.
Keep the unit away from liquids.
Before cleaning, unplug the power cord. Do not use chemical or aerosol cleaners. Wipe with damp
paper towels.
To prevent the unit from falling over, do not place it on carts or any unstable surfaces.
The power cord must plug into the correct supply voltage. Ensure the supplied AC voltage is correct
and stable.
Warning, electric shock hazard. To remove all electrical current from the device, ensure that all
power cords are disconnected from the power source.
Risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries
appropriately.
Power cord must be plugged into a socket-outlet with earthing connection.
Keep body parts away from moving fan.
This product must be installed by qualied personnel in a restricted access location (like dedicated
equipment rooms, service closets).

Tools and Parts for Component Installation
Please prepare below tools and parts before setting up your Synology NAS:
• A screwdriver
• At least one 2.5" SATA drive (please visit www.synology.com/compatibility for compatible drive models)
Warning: If you install a drive that contains data, the system will format the drive and erase all existing data.
Please back up any important data before installation.
• Rail mounting kit (please see the Optional Accessories section to nd out the suitable rail kit for cabinet
installation)
Warning: We suggest mounting your Synology NAS on a cabinet before installing any drives since the heavy
weight will increase the installation di󰀩culty.
