Install Memory Modules

Optional Synology memory modules are designed to expand the memory of your Synology NAS. Follow the steps
below to install, check, or remove a memory module on your Synology NAS.
The following table shows the memory configuration for best practice:

 

To install the RAM module
1 Shut down your RS2821RP+. Disconnect all cables connected to your RS2821RP+ to prevent any possible
damage.
2 Remove the screw on the back of you RS2821RP+. Slide open the rear top cover, then lift it up and put it
aside.

 

3 The memory slots are labeled as below

 

 

4 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 Apply firm and even pressure to push down the memory module. The retaining clips will snap into position
when the module is inserted correctly

 

5 Place the rear top cover back and slide it into secure position:
a Align the hexagons at the side of the rear top cover with the slots on the chassis’ edge, place it back and
push it to slide it back into position.

 

b Put back and fasten the screw you removed in step 2.
To confirm that your RS2821RP+ recognizes the new memory capacity
1 Install DiskStation Manager (DSM). Please see “Install DSM on Synology NAS” for more information.
2 Sign in to DSM as admin or a user belonging to the administrators group.
3 Go to Control Panel > Info Center and check Total Physical Memory.
If your Synology NAS does not recognize the memory or does not start up successfully, please make sure that
the memory module is installed correctly.

3 Push the retaining clips on the slot out to the sides. The memory module will pop out of the slot.
