This step could really use a better illustration of the removal technique. The plastic here is extremely stiff and it can be hard to bend it enough to move the tabs.

This is the best technique I found, that will avoid damaging the plastic facing of the case. I am using the iFixit photo as a guide. Take a flathead screwdriver and place it down within the DS412, head facing up. Stick the head in between the metal bar and the plastic casing, and at the midpoint between the two tabs. Apply gentle pressure.

Hi is it also possible with a Synology ds216play? Or is the RAM not modular in this Drives?

Thank you for the guide, just to ease it up a bit for everybody following, the best way to pull the two tabs from step 4 was to use small spoon (or anything metal) and use it as a crowbar from the inside (do not try to put force from the outer rim, but really from inside of the Synology itself (against the metal beam the tabs are holding to).

did these steps and now my DS412+ won't boot anymore. just the blue power light for a few seconds, no hard drive or fan will turn on.

after putting the old RAM in the slot nothing changed. cannot find any error, how do I find out what's wrong here???
