Introduction

Teardown of the D-Link NAS DNS-323.

Fairly easy to open.

This teardown is not a repair guide. To repair your D-Link DNS-323, use our service manual.

The DNS-323 is a powerful NAS with Gigabit Ethernet, print server and extension via software. It can have a FTP server, DHCP, and even Bittorrent! This is my first disassembling, please be patient, correct my grammar mistakes if you find some. This was pretty easy, nothing compared to iPods or Macs.

First thing first remove the frontal part by sliding it up and pulling out. You will be able to see the hard disks.

    • You will be able to see the hard disks.

  • By the way, the DNS-323 can support up to 3TB of disk space with the new firmware update. That's 1.5TB per disk! Could you imagine such capacity twenty years ago?

Do you mean 3TB?

did you mean per disk

Now it's time to remove the Hard Disks. BE CAREFUL, when handling these parts do not touch the circuits, do not shock, and do not let your dog play with them. I'm serious, this could lead into data loss. At the back of the DNS, pull out the two little levers to make the hard drives come out.

    • Gently put them in a safe place until the whole unit is reassembled.

  • The drives are order-specific! Remember if they were right or left, otherwise you will be prompted with a message when accessing the NAS after reassembly.

Remove the frontal part. There are two screws; remove them with a cross screwdriver.

    • Pull off the little sheet of metal that's covering the front.

Now it's time to open the rear. Locate the four rubber caps which cover the screws,  then remove them with a flat screwdriver. Remove the screws.

Take off the rear and unscrew the next four screw showed in the picture. These screws are hard! Pay attention not to strip them! These screws are hard! Pay attention not to strip them!

Pull the board to make it slide out of the case. The board is quite simple, a little ARM-based computer mounting Linux. (is it?). The condensers are mostly for power supply, doubled because of the two HDDs. Remove two more screws under the circuit.

Time to remove the iron part. Pull out the fan wire. If you need you can use a flat screwdriver, paying attention not to break it. It's time to detach the SATA adapters with the fan, so you can contemplate the main circuit.

  • Don't remove the battery as this could lead to time loss, some basic (board-level) settings, and unwanted resets.

Now all about the chips The first chip looks like a flash memory for the ROM, or the random memory for the OS, there are two of them; Labelled 921EA C HY5DU56 1622FTP-043 Made in Korea NWFM136SAG3 Marvell 88F8152-A2 "Feroceon(r)" Storage Networking SoC (System-on-Chip)

    • A 12 to 24 bit multiplexed D-type latch marked 94CJNQK ALVCH162260 , see more there -->

    • Eon SiliconSolution Inc EN29LV640B-90TIP 64Mbit Flash memory

The purple boxed chip is a 12 to 24 bit multiplexed D-type latch: http://focus.ti.com/docs/prod/folders/pr...

Probably the address buffer for the NOR flash allowing a large device to be mapped into a small address window.

Thank you, corrections have been added to the guide!

Last chip... Marvell Alaska 88E1111 single-port GbE transceiver.  Markings: 88E1111-BAB1 6MAE490301.4 0914 B2P Taiwan Remove the last screws.

  • Remove the last screws.

    • That's not useful unless you want to replace the fan; six screws keep the two SATA connectors and...

    • ...four tapping screws hold the fan.

Thank you so much! It's only my first guide, but I'm going to post fun stuff lately!

Please always watch for grammar mistakes!

Very nice teardown. The pictures were very clear unlike my iPhone dock tear down. I'm making another teardown today. Keep up the good work Mc128k! :)
