Safety Instructions

Hard Drive Installation (For Diskless Version Only)
This section shows how to install hard drives into a 223
Did you purchase your 223 preloaded with Hard Drives?
Skip to “Initial Setup of Disk Station Manager” on page 13.
Tools and Parts for Hard Drive Installation
Needed:
- A Phillips screwdriver
- 3mm Hex Tool (included with the ioSafe 223)
- At least one 3.5” SATA hard drive (Please visit https://cdsg.com/hardware-compatibility for compatible hard drive models.)
Note: For a RAID1 set, it is recommended that all installed drives be the same size to make the best use of hard disk capacity.
Warning: If you install a hard drive that contains data, the 223 will format the hard drive and erase all data. If you need the data in the future, please back it up before installation.
Install Hard Drives
- Remove the Front Cover using the included 3mm Hex Tool.

NOTE: All hex screws used in the 223 are designed to be captive to avoid accidental loss. - Remove the waterproof Drive Cover using the 3mm Hex Tool.

- Remove both of the Drive Trays using the provided 3mm Hex Tool.

- Install a compatible Hard Drive into each Drive Tray using (4x) Drive Screws and a Phillips screwdriver. (Please visit https://cdsg.com/hardware-compatibility for compatible hard drive models.)

- Insert the Hard Drives into the empty hard drive bay and tighten the screws using the 3mm Hex Tool.
Note: Each Hard Drive will only fit in one orientation.
Note: If a Drive replacement is required, note that Drive #2 is on the left and Drive #1 is on the right.
- Replace the Waterproof Drive Cover and securely tighten using the supplied 3mm Hex Tool.

WARNING: BE SURE TO TIGHTEN THIS SCREW USING THE HEX TOOL. THE HEX TOOL IS DESIGNED TO FLEX SLIGHTLY WHEN THE SCREW IS SUFFICIENTLY TIGHT AND THE WATERPROOF GASKET IS COMPRESSED PROPERLY. AVOID USING TOOLS OTHER THAN THE SUPPLIED HEX TOOL, AS YOU COULD OVER-TIGHTEN OR BREAK THE SCREW. - Install the Front Cover to finish the installation and protect the drives from fire. Store the hex tool on the back of the device using the supplied magnet for later use.

Connect the ioSafe 223 to your Network
- Use the LAN cable to connect the ioSafe 223 to your switch/router/hub.
- Connect the AC adapter to the power port of the ioSafe 223. Connect one end of the AC power cord to the AC power adapter, and the other to the power outlet. Insert the plastic cable holder into the slot to retain the power cord.
- Press and hold the power button to turn on your DiskStation.

Your ioSafe 223 should now be online and detectable from a network computer
Initial Setup of Disk Station Manager
After the hardware setup is finished, please install Synology’s DiskStation Manager (DSM). Synology’s DiskStation Manager (DSM) is a browser-based operating system that provides tools to access and manage your ioSafe. When installation is complete, you will be able to log into DSM and start enjoying all the features of your ioSafe powered by Synology. To get started, please see the steps below.
Note: Before beginning the installation process below, make sure that the 223 is connected to your router/switch with the network cable and that the power cord is plugged in and the 223 is powered on.
Connecting to the ioSafe using Web Assistant
Your ioSafe comes equipped with a built-in tool called Web Assistant that helps you download the latest version of DSM from the internet and install it on your ioSafe. Before installing DSM with Web Assistant, please check the following:
- Your computer and your ioSafe must be connected to the same local network.
- In order to download the latest version of DSM, Internet access must be available during installation.
After confirming, please follow the steps below:
- Power on your ioSafe.
- Open a web browser on your computer connected to the same network as the ioSafe.
- Enter either of the following into the address bar of your browser:
- find.synology.com
- Diskstation:5000
Note: Web Assistant is optimized for Chrome and Firefox web browsers.
- Web Assistant will be launched in your web browser. It will search for and find the DiskStation within the local network. The status of the DiskStation should be Not installed.

- Click Connect to start the setup process. Follow the onscreen instructions to complete the setup process.
Note:- ioSafe uses an unmodified version of Synology’s DSM. The software interface will sometimes refer to the Synology Product the ioSafe is based on, Synology DS223.
- Suggested browsers: Chrome, Firefox.
- Both the 223 and the computer should be on the same local network.
- Internet connection must be available during DSM installation with Web Assistant.
- A web browser should open, showing the 223 Login screen. Enter the ‘admin’ as the username and leave the password field blank as shown below.

SystemModess and LED Indicators
There are 7 system modes in Synology NAS. The System modes and their definitions are as below:
| System Mode | Definition |
| Powering on | Synology NAS powers on when you press the power button or restarts when you run operations in DSM. During the boot-up process, the device also performs 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 operating in DSM. |
| 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 insufficient 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. |
| Application | Synology NAS is powered off. |
Identify System Modes
You can identify the system mode through the POWER and STATUS LED indicators. Please refer to the table below for more details.
| System Mode | POWER LED | STATUS LED | ||
| Blue | Green | Orange | ||
| Powering On | Blinking | Off | Off | |
| Shutting down | Blinking | Static | Off/Static1 | |
| DSM not ready | Static | Blinking | Off/Blinking1 | |
| DSM is ready for use | Static | Static | Off/Static1 | |
| Hibernation | Static | Off | Off/Static1 | |
| Application | Static | Switching | ||
| Powering Off | Off | Off | Off | |
Notes
If the STATUS LED remains static orange or continuously blinks orange, this indicates there are system errors such as fan failure, system overheating, or volume degradation. Please sign in to DSM for
Detailed information.
- Transitions between System Modes
To better understand the transition between system modes, please refer to the examples below: - Powered on with no DSM installed:
Powered off > Powering on > DSM not ready - Powered on with DSM installed:
Powered off > Powering on > DSM not ready > DSM is ready for use - Entering hibernation, then waking up from hibernation:
DSM is ready for use > In hibernation > DSM is ready for use - Shutdown:
DSM is ready for use > Shutting down > Powered off - Power failure with UPS attached:
DSM is ready for use > DSM not ready (due to power failure, DSM enters safe mode) > Shutting down > Powered off > Powering on (power has recovered, DSM will reboot) > DSM not ready > DSM is ready for use
