Tools and Parts for Component Installation
Please prepare the tools and parts below before setting up your Synology NAS:
• A Screwdriver
• At least one 3.5” or 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.

12 Chapter 2: Hardware Setup
Add a RAM Module on Synology NAS
The optional Synology RAM module is designed for Synology NAS memory expansion. Follow the steps below to
install, check, or remove a RAM module on your RS820+ / RS820RP+.
To install the RAM module:
1 Shut down your RS820+ / RS820RP+. Disconnect all connected cables to prevent any possible damage.
2 Remove the top cover:
a Loosen the four screws on the top cover of the RS820+ / RS820RP+ with a screwdriver. Respective screw
position is indicated above.
b Push forward the top cover to the front-end of your RS820+ / RS820RP+, as indicated above.
Note: When you remove the top cover, you expose sensitive internal components. Avoid touching anything other than
the memory assembly when you remove or add memory.
Important: RS820+ / RS820RP+ does not support ECC, regardless the expand memory being ECC or non-ECC.
Note:
1. When memory capacity is changed, the device will perform a memory check upon the next start up. This will
prolong the start up time by up to ten minutes. This behavior is normal and will only occur once.
2. Synology will not provide complete product warranty or technical support if non-Synology RAM modules are used
for memory upgrade.

13 Chapter 2: Hardware Setup
3 Insert the new memory module in the slot:
a Align the notch on the gold edge of the module with the notch in the memory slot.
b Tilt the card and push the memory into the slot. Make sure the module is pushed in all the way.
c Use two ngers to apply rm, even pressure and push the memory module downward. You should hear a
click when the memory is inserted correctly.
Important: Hold the memory module by its edges, and do not touch the golden connectors.
4 Return the top cover into the RS820+ / RS820RP+:
a Align the round dots at the side of top cover with the slots on the chassis' edge, and push the top cover back
into position.
b Fasten the four screws you removed in step 2.
To make sure RS820+ / RS820RP+ recognizes the new memory capacity:
1 Install DiskStation Manager (DSM). (See the next chapter for more information.)
2 Log in to DSM as admin or a user belonging to the administrators group.
3 Check Total Physical Memory in Control Panel > Info Center.
If your RS820+ / RS820RP+ does not recognize the memory or does not start up successfully, conrm that the
memory is installed correctly.

14 Chapter 2: Hardware Setup
To remove the RAM Module:
4 Follow step 1 and 2 of the Add a RAM Module on Synology NAS section to shut down your RS820+ /
RS820RP+, disconnect the cables, and then remove the top cover.
5 Disengage the memory retaining clips by pushing them outwards, and the module will pop out of the slot.
6 Follow step 4 of the Return the top cover into the RS820+ / RS820RP+ section to put back the top cover.
Install PCle Add-in Cards
RS820+ / RS820RP+ provides one PCIe slots for optional add-in card expansion, allowing network interface
cards or M.2 SSD adapter cards to be installed.
To install the network interface cards:
1 Shut down your RS820+ / RS820RP+. Disconnect all cables connected to your RS820+ / RS820RP+ to
prevent any possible damages.
2 Open the RS820+ / RS820RP+ by following step 2 of the To install the RAM module section.
3 Install the network interface card.
a Lift the black latch from the expansion slot cover. Remove the cover from the expansion slot.
b Align the gold connectors of the network interface card to the expansion slot, and insert the card rmly into
the slot.
c Put the black latch back to the expansion slot to fasten the network interface card.
Note: Make sure the connector is fully inserted. Otherwise, the network interface card might not be able to function
properly.
4 Put back the top cover by following step 4 of Add a RAM Module on Synology NAS.

15 Chapter 2: Hardware Setup
To install M.2 SSD Adapter Card - M2D18:
Before installing a M.2 SSD adapter card into your RS820+ / RS820RP+, you should assemble the M.2 SSDs
into the adapter’s bracket along with the heatsink for better heat dispatching.
1 Assemble M.2 SSD:
a Push the SSD all the way into the xed bracket until it is rmly seated.
b Remove the release papers from the thermal pad of the heatsink.
c Align the heatsink with the clips of the bracket and press the four corners down. Please make sure the
heatsink is rmly attached to the clips to ensure the smooth running of the SSD.
2 Add M.2 SSD to M2D18 adapter card:
a Place a nut (1) and fasten a screw (2) to secure it.
b Insert M.2 SSD into the slot. Make sure the card is fully inserted.
c Tighten the SSD with a screw.
d Repeat previous two steps if installing another optional SSD is needed. Slot numbers are shown as below.

16 Chapter 2: Hardware Setup
3 Install the M2D18 adapter card:
Follow the steps of To install the network interface cards.
4 To disassemble the heatsink module:

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.

18 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.

19 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.
Start up Your Synology NAS
To start up your RS820+ / RS820RP+:
