Introduction

‘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).

*This is a step forward, the previous revision 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 by better components).

The dismantling time is estimated at one hour (but with photographies). That said, it is certainly achievable in 20/30 minutes.

The photographs were taken with an iPhone SE, using a portable LED studio.

  • : info. must be checked.

Step 1

              Case presentation:  front panel
  • This NAS DS718 + is equipped with 4 GB of RAM (6 GB max.), an INTEL Celeron J3455 64-bit Quad processor, two bays for SATA drives (HDD, or SSD).
  • FRONT PANEL : you can notice on the right side, disks LEDs disapeared. You can find them now just on the top of the disk bays.
  • status LEDs
  • power buton (startup / shutdown)
  • 1 x USB 3 port
  • “copy” buton
  • 2 x disk support (caddy / cage)
  • disk bay lock

Step 3

              Backplane and memory access
  • Before teardown, unlock the disk media with the key.
  • It’s a new appreciable feature, the memory slots are now directly reachable.
  • first memory slot
  • seonc memory slot (not populated)
  • The previous revision (DS716+ II) allowed this operation but a piece of metal prevent to remove memory.
