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 Synology NAS:
• A screwdriver
• At least one 2.5” SSD (SAS/SATA) or HDD (SAS only) (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.
Install Drives
Please follow the steps below for drive installation:
1 Open the drive tray.
a Find the small button located on the bottom 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 Place the drive in the drive tray. Tighten screws into the four spots indicated below to secure the drive.

Follow the steps below to install, check, or remove a memory module on your FS3600.
To install the RAM module:
1 Shut down your FS3600. Disconnect all cables connected to your FS3600 to prevent any possible damage.
2 Remove the screw on the back of FS3600. Pull the rear top cover, and put it aside.
Note: When you remove the rear top cover, the sensitive internal components are exposed. Avoid touching anything
other than the memory assembly when you remove or add memory.

12 Chapter 2: Hardware Setup
3 Insert the new memory module in the slot:
a Push the retaining clips on the slot out to the sides.
b Align the notch on the gold edge of the module with the notch in the memory slot.
c Push down on the memory module with rm and even pressure. The retaining clips will snap into position as
the module is correctly inserted.
Note: Hold the memory module by its edges, and do not touch the gold connectors.
4 Put back the rear top cover you lifted in step 2.
a Align the hexagons at the side of rear top cover with the slots on the chassis’ edge, and push the rear top
cover back in position.
b Put back and fasten the screw you removed in step 2.

13 Chapter 2: Hardware Setup
To make sure FS3600 recognizes the new memory capacity:
1 Log in to DSM as admin or a user belonging to the administrators group.
2 Check Total Physical Memory in Control Panel > Info Center.
To remove the RAM Module:
1 Follow step 1 and 2 of the To install the RAM module section to shut down your FS3600, disconnect the
cables, and then remove the rear top cover.
2 Cut the cable tie before removing the memory module. (The pre-installed memory module is cable tied to
prevent loosening during delivery.)
Note: Avoid touching any components of the motherboard when you cut the cable tie.
3 Disengage the memory retaining clips by pushing them outwards, and the module will pop out of the slot.
4 Follow step 4 of the To install the RAM module section to put back the top cover.
Install PCle Add-in Cards
FS3600 provides one PCIe x8 slot for optional add-in card expansion, allowing network interface cards to be
installed.
To install the network interface cards:
1 Shut down your FS3600. Disconnect all cables connected to your FS3600 to prevent any possible damages.
2 Open the FS3600 by following step 2 of the To install the RAM module section.
3 Install the network interface card.

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.

16 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 Pull and hold the front latch of the inner rail to unlock the inner rail, and 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.

17 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.

18 Chapter 2: Hardware Setup
Expansion Unit Deployment and Topology
FS3600 supports up to two expansion units connection with RX2417sas (24-bay) and RX1217sas (12-bay),
providing seamless storage expansion whenever needed. This section will guide you through how to connect the
expansion units to your Synology NAS.
To connect RX1217sas/RX2417sas with FS3600:
1 Connect one end of the expansion cable to the SAS OUT port of your FS3600 and the other to the SAS IN port
of RX1217sas/RX2417sas. Make sure the release band (in blue) of the cable faces rightward when plugging
into the FS3600, and that of the cable faces upward when plugging into RX1217sas/RX2417sas; otherwise,
the FS3600 and expansion unit will not be correctly connected.
2 Connect one end of the power cord(s) to the power port of RX1217sas/RX2417sas, and the other to the power
outlet(s). RX1217sas/RX2417sas will automatically power on once the power cords are correctly connected.
Note: Your RX1217sas/RX2417sas 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.
Important: Do not remove the expansion cable while the host device is still powered on. Doing so may result in data
loss.

19 Chapter 2: Hardware Setup
3 Press the power button on the front panel to power on your FS3600. The expansion unit ID of RX1217sas/
RX2417sas connected to FS3600 will be displayed in sequence on the back panel.
Note: Even with the Synology NAS and expansion unit(s) powered on, you can still expand with one or more
expansion unit if needed. To do so, repeat above steps to connect the expansion cables and power cords of the other
expansion units. Your expansion units will automatically power on if they are correctly connected, and the expansion
unit ID will be displayed accordingly after a few seconds (if DSM is correctly installed in the Synology NAS server).
Start up Your Synology NAS
To start up your FS3600:
1 Connect one end of each power cord to the power ports located on the back of the FS3600 and the other end
to a power outlet.
2 Connect at least one LAN cable to one of the LAN ports and the other end to your switch, router, or hub.
3 Press the power button to turn on the FS3600.
Congratulations! Your Synology NAS is now online and detectable from a network computer.
