Introduction

Here's a step-by-step tutorial to dismount DS1019+ NAS until you reach the motherboard.

'Note: the interest of this tutorial is however limited.'

Indeed, most of the components that a user can be brought to add or change are now accessible directly, without disassembly (storage disks, memory expansion, SSD cache).

This is a step forward since, for example, a DS415 + / DS916 + must be completely removed to change a single RAM array.

Only the memory stack on the motherboard and fans remain inaccessible directly and require the disassembly of the NAS described in this tutorial to be changed (whether they are HS or replace them not the best).

The dismantling time is estimated at one hour (a single experiment on the timer). That said, it is certainly achievable in 20/30 minutes.

The photographs were taken with an iPhone Xr, un trépied SIRUI T-025SK, using a portable LED studio.

nota : le résultat est acceptable, mais en régression niveau qualité (manque de temps pour traitement des photos et qualité focus / netteté).
