Synology DS216+II: Upgrade memory

Step 1: Removing the front panel

First, we remove the rubber-mounted front panel, now we can see both hard drive slots.

Step 2: Removing the hard drive slots

The release button needs to be pushed to remove the hard drive slots, then the hard drive can simply slot be pulled out.

Step 3: Screw loose the fan grille

Now we loosen the four screws of the fan grille on the backside of the DiskStation and remove the fan grille.

Step 4: Loosen the case cover

ADVICE: This step is the most sensitive of the entire upgrade. Take your time and act with care.

• The case cover is locked in place to the frame of the hard drive cage with two locking lugs. We use two flat screwdrivers to loosen these. We simultaneously place these on the sides of both locking lugs and then use these to carefully press the casing outwards.
• When the locking lugs have been pressed outwards, the casing cover needs to be simultaneously moved backwards. It might be advisable in certain situations to ask a friend or family member for assistance. It is easier with four hands, should however be possible relatively effortless alone with some skill.
• The casting cover can be removed upwards as soon as it has been loosened and moved backwards. Now, the hardest part of this upgrade is done

Step 5: Removing the cooling fan

After we have removed the casing cover, we now need to remove the cooling fan of the DiskStation. To do so, we loosen the screw at the black angle mounting bracket, remove the connector of the fan cable from the board and remove the cooling fan.

Step 6: Removing the hard drive cage

We now need to dismount the metal hard drive cage to reach the socket for the RAM from the casing.

• Two screws with round heads are located on the top + bottom side each. We loosen these 4 screws with the Phillips-head screwdriver.
• The connection plate between the hard drive cage and the backside of the casing can be loosened directly with one single screw located on the hard drive cage. The screw at the back of the casing does not need to be removed.

Step 7: Replacing the random access memory

We have finally reached our goal; the RAM socket is right in front of us:

• The memory module is kept in place by a metal clip at the left and right-hand side. Both clips need to be carefully pushed outwards. Afterwards, the memory module lightly pops upwards and it can be removed from the socket.
• Now, the new memory module can be inserted. Press the memory module into the mounting at a light angle. Afterwards, push the memory module downwards, so that it snaps into the metal clips at the sides.
