Wyse Dx0Q (5020): Hardware 


 


 

 



Wyse Dx0Q

The D class is also known as the 5000 range and the Dx0Q is the same as a 5020.

As you would expect there is a great deal of commonality between the Dx0Q and the Dx0D, after all the headline difference is the inclusion of the Quad Core AMD CPU rather than the dual core one of the Dx0D series. However there are other differences and so I thought the 'Q' warranted an entry of its own.

More details of the D-class range can be found here.

D10DP label

My example is a D90Q8, part # 909882-02L, manufactured in May 2016. The label implies it should have been fitted with a 32GB flash drive and had Windows 8 installed. The unit came without any flash drive - maybe stripped out and sold separately?

As with most current models this came with the WYSE name on the front panel and the DELL name moulded into the side panels.

Power Supply

No power supply came with this so I used a 19V 3.42A Delta Electronics PSU. Note: The 19V rating. If, like me, you have a number of PSUs and thin clients floating around you need to mark this PSU clearly in some way. I'm sure that those which run from 12V - which is most of them - would not take too kindly to 19V. The coax plug is 5.5mm/2.5mm.

Getting Inside

This is fairly straightforward. You need to remove the foot (if fitted) and then the three screws on the back panel. The plastic side cover then slides back a short way can be lifted off. This reveals a metal shield that is dealt with in a similar fashion. This time there are screws in each corner to be removed and a final one in the centre of the edge by the front panel. Once again this panel is slid a short distance towards the rear before it can be lifted clear. (There are three metal lugs each side that locate in small slots in the metal chassis that lock it in place). The speaker is fixed to this panel and will need to be disconnected from the board near to the SODIMM.

Expansion

Dell Wyse Dx0QP internal view Click on the photo for a larger version.

Flash: The flash is a small horizontal SATA DOM (missing in my case). There is also a separate SATA data connector on the board.

RAM: The RAM is a 204-pin DDR3L SODIMM can be seen bottom-left in the photograph. The one fitted is a Hynix part: HMT451S6BFR8C-PB NO AA and is labelled 4GB 1Rx8 PC3-12800S-11-13-B4. There are two RAM sockets, one above the other. My pocket doesn't run to a DDR3 8GB RAM so I don't know if the limit is 2 x 4GB or 2 x 8GB.

The SODIMM sockets are more accessible than on the Dx0D range as the front panel board has been redesigned so that it no longer overhangs the SODIMM. I do have a Dx0D of a later manufacturing date (September 2016) which is the same as the earlier examples I had which implies that this change is unique to the 'Q' version.

mPCIe: There is a mPCIe socket adjacent to the SATA socket.

TPM:The specification mentions a Trusted Platform Module (TPM). In my case I don't think this is fitted - possibly removed by the vendor? Tiny core Linux doesn't find it but maybe the TPM support modules aren't in the distribution? (Neither does Fedora 28 Workstation find it). As you can see above the label on the unit does read: D90Q8 15W TPM 32GMF/4GR ES INTL which implies one might have been fitted originally.

There are a few other connectors dotted around the circuit board most of which I don't know the purpose of.

Additional Photos

The double-banked RAM sockets.

Dx0Q vRAM sockets

Along the bottom edge of the circuit board we have:

Dx0Q various board connectors

CN4400. A Link. For what? It has 'Protection' silk-screened by it.

CN2600 that looks like a connector for two more USB ports. It is marked 'Developer'.

CN5 which is a ZIF connector - similar to the keyboard connector on some laptops.

Checking the Dx0D board (where the sockets aren't fitted) we can see the 'Protection' link and can see that the 'Developer' connector only has three lines connected. (Data in/out and ground of a serial debug port?).

Dx0D various board connectors

Near the power connector we have:

Dx0Q various board connectors

CN1700 a small 4-pin JST socket. I measure +5V on the two pins closest to the heatsink. Could be power for another SSD?

CN6 4-pin JST socket - I measure +12V on the two pins closest to the front panel. Could be power for a fan?

CN1601 6-pin socket.

Near the SATA Data socket and CPU heatsink:

Dx0Q various board connectors CN3 Dual row of small pins (2 x 15).

As with the Dx0D I haven't taken the motherboard out of the housing, but I did notice whilst peering in through the ventilation slots, a push switch mounted on the rear of the board. Whilst on the Dx0D nearby to this is the word 'BIOS' on the Dx0Q board it is marked with a more anonymous label of 'SW7004'.
