Safety Instructions
Keep away from direct sunlight and away from chemicals. Make sure the environment does not
experience abrupt changes in temperature or humidity.
Place the product right side up at all times.
Do not place near any liquids.
Before cleaning, unplug the power cord. Wipe with damp paper towels. Do not use chemical or
aerosol cleaners.
To prevent the unit from falling over, do not place on carts or any unstable surfaces.
The power cord must plug in to the correct supply voltage. Make sure that the supplied AC voltage is
correct and stable.
To remove all electrical current from the device, ensure that all power cords are disconnected from
the power source.
Risk of explosion if battery is replaced with an incorrect type. Dispose of used batteries appropriately.

Tools and Parts for Component Installation
Please prepare the tools and parts below before setting up your expansion unit:
• A Screwdriver
• At least one 3.5” or 2.5” SAS 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 expansion unit on a cabinet before installing any drives since the heavy weight
will increase the installation di󰀩culty.
Install Drives
Please follow below steps for drive installation:
1 Open the drive tray.
a Find the small button located on the left side of the drive tray handle. Press the button down, and the drive
tray handle will pop out.
b Pull the drive tray handle out as illustrated above.
2 Install drives:
• For 3.5” drives: Place the drive in the drive tray. Turn the tray upside down and tighten screws into the four
spots indicated below to secure the drive.
• For 2.5” drives: Place the drive in the drive tray. Turn the tray upside down and tighten screws into the four

Install and Remove Rail Kits
Here we use RKS1317 as an example to illustrate how to install or remove the rail kits. For more information
about the rail kit installation, please refer to the Quick Installation Guide that comes with the rail kit.
To install the rail kit:
1 To install the rail kit to the rack
a Attach the rear end of the rail kit assembly to the rack.
b Slide the front latch outwards and insert the brackets into the rack holes.
2 Extend and pull out the inner rail from the assembly.

11 Chapter 2: Hardware Setup
3 Align the xing holes of the inner rail to the side of the chassis and slide backward to attach the inner rail.
4 With the help of another person, carefully align the inner rail to the outer rail assembly.
5 Push the chassis towards the rack. Use the cage nuts and screws in the rail kit package to secure the chassis
to the rack if necessary.

12 Chapter 2: Hardware Setup
To remove the rail kit:
1 To remove the chassis from the rack, hold the rail kit release tabs on the ear holders and pull out the chassis
from the rack.
2 With the help of another person, carefully remove the chassis from the rack. Then, slide forwards to remove
the inner rail from the chassis.

13 Chapter 2: Hardware Setup
Connect with Synology Server
1 Connect one end of mini-SAS HD cable to the SAS port of your Synology server and the other to the SAS
IN port of RXD1219sas. Please make sure that the release band (in blue) of the cable faces rightward when
plugging into the Synology server, and that of the cable faces upward when plugging into RXD1219sas;
otherwise, your Synology server and expansion unit will not be correctly connected.
2 Connect one end of mini-SAS HD cable to the SAS OUT port on SAS module A of an expansion unit (e.g.,
module A1), and the other end to the SAS IN port on SAS module A of the next expansion unit (e.g., module
A2).
3 Connect one end of mini-SAS HD cable to the SAS OUT port on SAS module B of an expansion unit (e.g.,
module B1), and the other end to the SAS IN port on SAS module B of the next expansion unit (e.g., module
B2).

14 Chapter 2: Hardware Setup
4 Connect one end of the power cord(s) to the power port of RXD1219sas, and the other to the power outlet(s).
RXD1219sas will automatically power on once the power cords are correctly connected.
Note:
1. Your RXD1219sas comes equipped with a redundant power supply system, allowing two power cords to be
connected. The system may be powered on with only one power cord, but we recommend using two power cords
to avoid unexpected power failures.
2. After you have unplugged the power cord, please make sure all the indicator is o󰀨 before plugging the power
cord back in again; otherwise, the system may fail to boot.
Important: Do not remove the expansion cable while the host device is still powered on. Doing so may result in data
loss.
5 Press the power button on the front panel to power on your Synology server. The expansion unit ID of
RXD1219sas connected to Synology server will be displayed in sequence on the back panel.
