Wyse Zx0Q (7020): Hardware 


 


 

 



Wyse Zx0Q

This is one of those slightly confusing situations from the Dell/Wyse transition. The unit I purchased was sold as Dell WYSE 7020 Thin Client ZX0Q No RAM, Power Supply Or Stand. It is clearly marked on the label as a Zx0Q, however I can't find it in the various Z-Class datasheets I have tracked down. These just mention the Z90Q7 based on the Quad core AMD GX-420CA SOC 2.0GHz with integrated Radeon HD 8000 graphics. However a Dell 7020 datasheet offers the Quad-core AMD GX-420CA 2.0 GHz and the Quad-core AMD GX-415GA 1.5 GHz (Quad Display configuration). What I have is the latter model with the Quad Display configuration.

The Dell Wyse Z-class brochure that mentions the Z90Q7 is dated May 2013. The Dell 7020 datasheet is dated April 2017.

My Zx0Q has part No: 08WF82 and was manufactured in February 2018.

Note: I've only seen this single version of the Zx0Q/7020. Whether there are significant mechanical/electrical differences between the various units that come under this name I have no real idea. However, in researching things, I came across a photo of a unit with a SSD fitted (see the Mods tab). This photo shows a more extensive heatsink in place which I guess reflects the 25W TDP of the GX-420CA. With my quad display Zx0Q some of this heatsink has been removed to create space for the add-on dual video board, so I assume a knock-on effect of this was the switch to the GX-415GA which has a lower TDP of 15W.

The flash in my Zx0Q had been wiped. The 7020 datasheet gives the possible OS as:

  • Windows Embedded Standard 7/7P/8
  • Windows 10 IoTEnterprise, 64 bit
  • Wyse ThinLinux

Power Supply

The Zx0Q runs from a 19V PSU. The connector is a standard 5.5mm/2.5mm coax plug.

I have highlighted in red the two lines contributed by the additional video board.

Click on the photo for a larger version.

Both the Flash memory and the RAM in the Zx0Q are easily(?) replaceable. (Not so easily in this version with the added video board).

Flash: The flash is a small horizontal SATA DOM on the motherboard. In this version it is under the video board (top right in the photo) that you need to remove to gain access. (See the Disassembly tab). Although the RAM had been removed from my Zx0Q the 32GB SATA DOM was still present.

There is also another SATA data socket on the board. (See the Mods tab for an example of this in use)

RAM: The board carries two SODIMM sockets for DDR3 RAM. My Zx0Q came without any RAM fitted. The SODIMM sockets are located underneath the metal carrier (center left in the photo) that is designed to carry a standard 2.5" SSD.

I tried out an 8GB part (Hynix PC3L-12800S) and a 4GB part (Elpida PC3-12800S) both of which worked. If only a single SODIMM is fitted it has to be in the upper SODIMM slot.

Additional Photos

SATA connector on the Wyse Zx0Q SATA: With the video board out of the way you can see the SATA module (top leftish) and SATA data socket (rightish, just above a white socket).

Top right you can see a white socket with a black plug and cable fitted. The plug on the other end of the cable is the white plug just to the top left of the SATA DOM. This is the power cable to the added video board. Under the Mods tab you can see this same socket being used as the power connector for an added SSD.

SSD caddy fitted to the Wyse Zx0Q Caddy: The SSD caddy fitted to the Zx0Q. I assume this is a standard fit as it isn't something that's required by the 'quad display' build. Mind you, having typed that, I remembered that the two tabs you can see at the top of the photo do act as supports for the board providing the additional two video ports.
