Fujitsu Siemens S900: Hardware 




Fujitsu Siemens Futro S900 Thin Client


The Fujitsu Siemens S900 is a neat unit that is based on a Fujitsu Siemens mini-ITX motherboard (D3003). The S900 was announced in May 2011. From the press release:

Fujitsu today announces the new FUTRO S700 and FUTRO S900 thin clients, the first Fujitsu thin clients to use innovative and eco-friendly Power over Ethernet (PoE) technology. Despite drawing only a trickle of power over Ethernet networks, the FUTRO S700 and FUTRO S900 are among the most powerful thin clients available today, boasting up to six times enhanced performance over previous models.

....The thin clients are even able to provide the processing capabilities to cope with rendering and performance-intensive 3D modelling: the Fujitsu models are among the first to introduce support for DirectX11 graphics technology.

The basic specs for the S900 are:

AMD G-Series
512MB/1GB (max 4GB)
   Max resolution
Radeon 6xxx
1920 x 1200 32-bit colour (DVI)
2560 x 1600 (display port)
10 x USB2.0
Kybd & mouse
20V 2A (Label)
5.5mm/2.1mm coax
H x W x D (mm)250 x 50 x 180

My S900 came without any flash memory fitted and so no operating system. The literature indicates that it either comes fitted with the eLux operating system or Windows Embedded Standard. The case of my S900 carries a sticker for Windows Embedded Standard (WS7E).

As far as CPU/RAM is concerned, my S900 was fitted with the 1.2GHz T44R CPU and 2GB of RAM.

Power Supply

The S900 uses a small external power supply that provides 20V at 2A. The connector is a standard 5.5mm/2.1mm coax connector. (Note: If you have various other thin clients lying around take care you don't use this in place of a standard 12V supply!). The data sheet for the D3003 gives 19V +/- 10% as the input voltage range accepted by the board with a typical current drain of 1A.


The S900 is fitted with an AMD G-Series CPU. From AMD's publicity material:

The AMD Embedded G-Series processor is the world's first integrated circuit to combine a low-power CPU and a discrete-level GPU into a single embedded Accelerated Processing Unit (APU). This unprecedented level of graphics integration builds a new foundation for high performance multi-media content delivery in a small form factor and power efficient platform for a broad range of embedded designs. Based on a power-optimized core, the AMD Embedded G-Series platform delivers levels of performance in a compact BGA package that is ideal for low power designs in embedded applications such as Digital Signage, x86 Set-Top Box (xSTB), IP-TV, Thin Client, Information Kiosk, Point-of-Sale, Casino Gaming, Media Servers, and Industrial Control Systems.

According to the data sheet the associated GPU is:

  • AMD Radeon HD 6320 (in combination with AMD G-Series G-T56N)
  • AMD Radeon HD 6250 (in combination with AMD G-Series G-T44R)
  • AMD Radeon HD 6290 (in combination with AMD G-Series G-T40N)
So the graphics in my S900 is a Radeon HD 6250.

The Linux cpuinfo reports:

cpu family:20
model name:AMD G-T44R Processor


The details I can find on Fujitsu's site are all about the D3003-S. The S900 is fitted with the D3003-A12 board. (It's marked on a paper label that's only visible if you remove the memory SODIMM). The -Sxx variant has more features such as a second SATA port and other on-board connectivity.



As this is based on a mini-ITX board there is obviously plenty of expansion opportunity starting with a reasonable amount of free space within the case where disk drives could be fitted.

CPU: Whilst the model range apparently encompasses a number of different CPUs, these are specific builds. The CPU comes in a BGA package and so is soldered to the board and not socketed.

Flash: The board carries an mSATA socket and a conventional SATA socket. There is a connector by the SODIMM sockets labelled drive power.

RAM: The board has two SODIMM sockets for DDR3 1066MHz memory. Mine is fitted with a 2GB Micron part -MT8KTF25664HZ-1G4M1. According to the data sheet the maximum that can be fitted is 4GB (2 x 2GB).

USB: There are two USB sockets on the front and four on the rear. Internally there are two headers on the motherboard that provide four further USB ports (I've checked). The paper spec says 8 ports, but my maths makes it 10.

PCI: There is a PCI socket and a PCI-e x1 socket. You will need a right-angle adaptor if you wish to press these into use.
