Fujitsu Siemens S520: Hardware

Overview

Checking to see when the s520 was launched I came across the following on a news site:

SAN FRANCISCO, CA--(Marketwired - Sep 8, 2015) - AMD (NASDAQ: AMD) today announced that Fujitsu selected the AMD Embedded G-Series SoC (system-on-chip), formerly codenamed "Steppe Eagle," for the newest additions to the FUJITSU Thin Client FUTRO family. The new FUJITSU FUTRO S920, S720 and S520 are powered by AMD Embedded G-Series SoCs that couple high performance computing and graphics capability in a highly integrated, low power design. The updated FUJITSU FUTRO thin clients deliver 20% higher frequency at the top end of the performance envelope compared to previous generations, delivered through the AMD G-Series SoC.

At first glance I thought this was another Fujitsu thin client based on a mini-itx mainboard, but a ruler tells me the board size is 160mm x 160mm rather than the 170mm of a standard mini-ITX board.

The mainboard is a Fujitsu D3314-A11. Like with other Fujitsu thin clients the mainboard is available in various builds with, I think, the -A11 variant being one of the lesser ones. Unfortunately I haven't been able to track down a technical manual for the board.

Specifications

The basic specs for the S520 are:

Processor
Type/Speed	AMD G series:   GX-210HA @ 1.0GHz or   GX-212ZC @ 1.2GHz
Memory
Flash    RAM	4GB/16GB microSSD 2GB/4GB (max 8GB)
Video
Chip    Resolution	AMD Radeon HD 8210E (GX210HA) or   AMD Radeon R1E (GX212ZC) 1920 x 1200 32-bit colour
Ports
Video    Network    USB    Serial    Parallel    PS/2	1xDVI-I 1xDVI-D 10/100/1000 2 x USB 2.0 2 x USB 3.1 0 0 Kybd & mouse
Power
Power    Plug    Off    Idle    Running	19V-20V 2A (Label) Coax 5.5mm/2.5mm 0W 3W 5W
Dimensions
H x W x D (mm) (With stand)	185 x 88 x 174 170 x 43 x 174

My example of the S520 is fitted with the GX-210HA running at 1.0GHz, a 4GB microSSD and 2GB of RAM.

The Windows Embedded Standard 7 version comes with a 16GB microSSD and 4GB of RAM.

Disassembly

This is simple although not immediately obvious. Undo two screws on the back and then the top cover and front panel slide forwards and then can be lifted away.

Power Supply

The S520 uses an external power supply - needless to say my example came without one. The label on the case says 19V - 20V 2A. I used a 19V 3.4A PSU I had to hand. The interface plug is a standard 5.5mm/2.1mm coax plug.

My power monitor shows 4W with nothing connected to the PSU. When the s520 is plugged in and off it remains at 4W. When running it idles at 7W and rises to 9W when active. The S520 datasheet gives the power consumption as 3.5W for 'long idle' so it looks like the accurate figures are 0W/3W/5W.

CPU

My S520 is fitted with an AMD G-series GX-210HA running at 1.0GHz. This is a dual core CPU.

Expansion

Click on the photograph to get a more detailed view of the circuit board.

Flash: The Flash memory is soldered to the board and non-changeable. The data sheet identifies it as 'microSSD onboard flash memory with MLC technology'. In my S520 it is 4GB in size. The version that runs Windows Embedded has a 16GB version fitted.

RAM: The board has a single SODIMM socket for DDR3 memory. The S520 datasheet tells me it is DDR3, 1,600 MT/s, PC3-12800. My S520 has a Samsung part fitted: 2GB 1Rx16 PC3L-12800S-11-13-C3, part # M471B5674QH0-YK0. I also tried out a 4GB Elpida part (4GB 2Rx8 PC3-12800S-11-10-F3) that worked perfectly.

In December 2020 I heard from Raymond who reported that 8GB DRAM modules are supported.

PCIe: There is a PCIe/mCARD socket on the board. In December 2020 I heard from Raymond who reported that the slot did not support mSATA.

USB: It looks like there maybe an internal USB port(s) near to the RAM. I haven't checked this out.
