Wyse Z90D7: Hardware 


 


 

 



Wyse Z90D7

The Z50/Z90 series is larger than some thin clients, standing some 20cm (10") high. In comparison with many of the thin clients covered on this website it is quite modern, my version (Z90D7) being manufactured in August 2011.

A number of models share the same hardware base. We have the primary distinction of either an S or a D in the model number that indicates that they are fitted with either a single core or dual core processor. The Z50S and the Z50D run Dell Wyse Enhanced SUSE Linux. The Z90 models run Windows:

My Z90D7 has part No: 909587-02L and was manufactured in August 2011.

Power Supply

The power supply is a 19V 3.42A Delta Electronics PSU that requires a figure-of-eight style mains lead. 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, two screws on the back panel, and the two screws towards the rear of the unit - one on the top and one on the bottom. After that the side cover can be slid back and removed.

Wyse Z90D7 internal view

Click on the photo for a larger version.

Both the Flash memory and the RAM in the Z90D7 are easily replaceable.

Flash: The flash is a small horizontal SATA DOM which can be seen bottom-middle in the photo. To the left of this a vertical SATA data socket CN10 for an additional SATA device. I assume the nearby small black socket CN11 can be used for the power connection. My multimeter finds GND on the pins furthest away from the SATA socket and +5V on the two closest pins. This of course is no guarantee that they're actually connected to the +5V line and can deliver the required current.

RAM: The RAM is a 240-pin DDR3 DIMM. The board carries two sockets. The 2GB part fitted to my Z90D7 is a PC3-10600 part. Various memory suppliers put the maximum RAM capacity at 8GB (2 x 4GB).

USB: There is a spare header on the circuit board - CN13 (Yellow blob in the photograph of the SATA ports). I plugged a standard 10-pin motherboard-to-two-USB-sockets cable into it and found I'd gained an extra two USB ports.

mPCIe: There is a wireless module (WPEA-121N/W) plugged in to a mPCIe socket.

Connectors

There are also a series of other connectors dotted around the circuit board that I don't know the purpose of. However, for two of them:

SATA power connector on the Wyse Z90D7 CN11. This socket is adjacent to to CN10, the SATA data connector. I measure +5V on pins 1 & 2 (closest to the SATA socket) and GND on pins 3 & 4, so this is no doubt intended to supply power to a second SATA device. The connector is a micro JST connector with 1.25mm pin spacing. You can find suitable plugs with flying leads fitted on eBay - an example of which is shown fitted.

SATA power connector on the Wyse Z90D7 CN109: This socket is adjacent to CN13 (the USB header). I measure +12V on the two pins furthest from the USB socket, so this would appear to be a suitable pick-off point if something you're adding needs 12V power.

SATA power connector on the Wyse Z90D7 This socket has 2.0mm pin spacing but is not a JST socket and I'm not too sure exactly what fits it. However I did buy a pack of 10 2.0mm spacing micro JST plugs and found that, after I shaved off the two 'ribs' on the side of the plug which didn't quite line up with those on the socket, that the plug fitted really quite well.

For these types of connectors the suppliers are usually based in China and you'll end up with a packet of 10. If you're impatient you may be lucky and find an in-country supplier but at a premium, but then these don't cost much in the first place.
