Safety first
Stop and check this first
- If Synology Assistant reports DSM not installed, do not continue installing DSM or all data on the drives will be deleted; retrieve data from the drives first.
Safe checks you can perform
- Compare the LED pattern with your NAS model and DSM version
- Inspect the reported NAS status in Synology Assistant
- Check Storage Manager when Synology Assistant shows Ready
Leave these tasks to a qualified professional
- Do not attempt this professional task: Verify the Synology Assistant status and protect existing drive data
- Do not attempt this professional task: Replace the defective drive and run Storage Manager Repair

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Verify the Synology Assistant status and protect existing drive data
What they doThe technician correlates the STATUS and ALERT LEDs with the status reported in Synology Assistant and prevents any destructive DSM installation when DSM not installed or Configuration Lost is shown.
They must show youthe status string displayed in Synology Assistant and how it maps to Synology's LED status tables.
In writingNAS model, DSM branch, Synology Assistant status, and the steps taken to preserve data before remediation.
Replace the defective drive and run Storage Manager Repair
What they doWhen the NAS status is Ready with a degraded storage pool, the professional confirms the defective drive on the HDD/SSD page, replaces it with a compatible drive (powering off first if the model lacks hot-swap support), and selects Repair in Storage Manager.
They must show youthe defective drive identified on the HDD/SSD page, the replacement drive's compatibility and size, and the Repair task in Storage Manager.
In writingdrive bay number, replacement drive model and capacity, and the storage pool status after initiating Repair.
Before accepting a part or repair

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Compare the LED pattern with your NAS model and DSM version
- Who:
- you, inspecting the front panel of your 2015 or newer Synology NAS.
- How:
- check your Product Manual for the STATUS and ALERT LED locations and note whether the orange light is blinking or static alongside the ALERT indicator state.
- Result that matters:
- match your NAS against Synology's tables for models with or without an ALERT LED.
- If ALERT is off and STATUS blinks green on DSM 6.2.4 or above:
- review DSM readiness in Synology Assistant.
- If STATUS or ALERT is blinking or static orange:
- proceed to check the exact system status in Synology Assistant.
- Evidence to keep:
- observed STATUS and ALERT LED behavior and the exact Synology NAS model name.
Evidence: The STATUS or ALERT LED indicator keeps blinking or lights up steadily in orange. What can I do?
Inspect the reported NAS status in Synology Assistant
- Who:
- you, using a computer on the same local network as the Synology NAS.
- How:
- download Synology Assistant from the Download Center under Desktop Utilities, launch it to find your NAS, and read the Status column without starting an unverified DSM installation.
- Result that matters:
- identify whether the unit reports DSM not installed, Configuration Lost, Migratable/Recoverable, or Ready.
- If the status is Migratable/Recoverable:
- follow the Synology Assistant wizard to reinstall DSM without deleting shared folder data.
- If the status is DSM not installed or Configuration Lost:
- stop before installing DSM so drive data is not erased, and arrange data retrieval or support.
- Evidence to keep:
- screenshot or record of the exact Status string shown in Synology Assistant.
Evidence: The STATUS or ALERT LED indicator keeps blinking or lights up steadily in orange. What can I do?
Check Storage Manager when Synology Assistant shows Ready
- Who:
- you, signed in to DSM with administrator access when the status is Ready.
- How:
- open Storage Manager > Storage to see whether no volume has been created or whether a storage pool is Degraded or Crashed, and check the HDD/SSD page for drive status.
- Result that matters:
- confirm whether a volume simply needs to be created or a redundant storage pool requires drive replacement and repair.
- If no volume is created yet:
- create a volume in DSM Storage Manager following the help guide for your DSM version.
- If the storage pool is Degraded or Crashed:
- safeguard your files and follow the official storage pool repair or crash workflow.
- Evidence to keep:
- Storage Manager pool status and the individual drive states listed on the HDD/SSD page.

What it means
Synology's troubleshooting page for an orange STATUS or ALERT LED covers NAS models released in 2015 or later. On DSM 6.2.3 and below, blinking orange means DSM is not ready (no drive installed, DSM not installed, or Configuration Lost) or points to a volume issue; on DSM 6.2.4 and above, static orange on STATUS or blinking orange/red on ALERT indicates a degraded or crashed volume. This LED state alone does not prove that a drive or hardware part has failed.
