Fujitsu Siemens A250: Hardware 


 


 

 



Fujitsu Siemens A250 Thin Client

Specifications

The Fujitsu Siemens A250 is a small and neat unit that is similar in style to the VXL Percio. There is no date of manufacture on the unit but the BIOS carries a date of 2007 and the data sheet on Fujitsu's site is dated January 2008.

The basic specs for the A250 are:

The operating system is eLux NG. (see www.myelux.com). I actually bought this unit new for £10 plus postage and it comes with unlicenced software - you can apparently run it 38 times before it goes on strike if you haven't entered a valid licence number by then.

Power Supply

The A250 uses a small external power supply that provides a 12V 2A supply. The plug is a standard 5.5mm/2.1mm coax plug.

Expansion

board Flash: Like the VXL Percio the operating system is stored on a Compact Flash card that is concealed behind a cover on the left-hand side, so a change of operating system/flash memory size is just a matter of what is inserted here.

RAM: The RAM is a standard 200-pin SODIMM. The one fitted carries a label 256MB DDR 333 (aka PC-2700). In October 2016 Darek emailed me to say that he'd successfully installed 1GB of RAM.

IDE Interface: Unusually for modern thin clients the on-board IDE interface is a 40-pin one (CDROM/3.5" drive) rather than the more usual 44-pin laptop style.

Links: mfd emailed me to point out that jumper J3 - located at the corner of the board by the power switch - makes the system auto boot following a power failure.
