A. Product description
GuruPlug Server is a Linux based small form factor computer with AC plug which has the following unique
features.
1. Highly integrated all the peripherals necessary for a modern designed computer just into one chip.
2. Ultra low power consumption
3. Very high speed, the CPU is running at 1.2GHz with 800MHz DDR2 SDRAM.
With all these features described above you can just plug it into the wall’s AC outlet and running all year
round, it consumes much less power compared to almost all the computers on the market with the same
features.
B. Hardware features.
The hardware features are described in the “GuruPlug‐plus‐Block diagram.pdf” and
“GuruPlug‐plus‐Description of Hardware block diagram.pdf” documents which come along with this
document although separated, please refer to it.
C. Software features
This computer is installed with Linux ubuntu 2.6.32 kernel and all the device drivers for the hardware
peripherals support by this CPU like USB, Ethernet, PCIe, SATA … etc.
D. Important information to developer
1. It is only the computer with Linux OS without any applications pre‐installed, so basically it is only a
development platform and also a powerful tool for engineers to develop with.
2. Whatever the develop engineers may put on to it becomes the ultimate finish products they want it
to be, for example the file server, mail server or TV set‐top box.
3. When you power on, it will boot up automatically and run Linux OS then wait for your login and
stop there in the command prompt for you to enter the Linux command to go on.
4. Since it has no display interface like VGA or LCD so the developer has to connect a Linux PC to it or
use Windows or Linux PC remotely login to it through Ethernet.
E. Connection methods to PC
