CE certificate of conformity Important notes
2.2 CE certificate of conformity
2.3 ENERGY STAR
The board complies with the requirements of the EC directives
2004/108/EC regarding “Electromagnetic Compatibility” and
2006/95/EC “Low Voltage Directive”. This is indicated by the CE
marking (CE = Communauté Européenne).
Compliance was tested in a typical PRIMERGY configuration.
In some particular configurations1the PRIMERGY TX120 S2 is
equipped with a power management system which, in energy-
saving mode, reduces the power consumption to <65 W. The
server thus satisfies the requirements of the U.S. Environmental
Protection Agency (EPA).
The EPA estimates that computer systems use around 5 % of all
electricity in the office sector and that this figure is growing
rapidly. If all computer systems and peripherals were placed in
energy-saving mode when not in use, the overall savings in
electricity could amount to some US $ 2 billion annually. These
savings would also prevent the emission of 20 million tons of
carbon dioxide into the atmosphere - equivalent to the emissions
from 5 million automobiles.
As an ENERGY STAR partner, Fujitsu Technology Solutions
GmbH has determined that in some particular configurations this
product meets the ENERGY STAR guidelines for energy
efficiency.
1These servers are always delivered with a particular setting in the BIOS setup. For details
please see the manual “D2785 BIOS Setup Utility for PRIMERGY TX120 S2” on the
PRIMERGY ServerView Suite DVD 2.

Features Overview
TPM (option)
The system board can be equipped with a TPM (Trusted Platform Module) by
the manufacturer or by an add-on kit. This module enables programs from third
party manufacturers to store key information (e.g. drive encryption using
Windows Bitlocker Drive Encryption).
The TPM is activated via the BIOS system (for more information, refer to the
BIOS manual).
VCAUTION!
– When using the TPM, note the program descriptions provided by the
third party manufacturers.
– You must also create a backup of the TPM content. To do this, follow
the third party manufacturer's instructions. Without this backup, if the
TPM or the system board is faulty you will not be able to access your
data.
– If a failure occurs, please inform your service about the TPM
activation before it takes any action, and be prepared to provide them
with your backup copies of the TPM content.

Features PCI bus
3.3 PCI bus
PCI slots
Figure 3: Detail - PCI slots
PCI, PCI Express interrupts
Each device connected to a PCI bus or PCI Express can use up to four interrupt
signals depending on the functionality.
PCI and PCI-X buses use four lines named INTA to INTD, typically connected
to all devices on the bus in order to periodically balance interrupt load. An
interrupt signal may thereby be used simultaneously by multiple devices
(interrupt sharing).
PCI Express devices send their interrupts through messages. This avoids
restrictions in wiring.

Features Temperature / system monitoring
3.5 Temperature / system monitoring
Temperature and system monitoring aim to reliably protect the computer
hardware against damage caused by overheating. In addition, any unnecessary
noise is also prevented by reducing the fan speed, and information is provided
about the system status.
The temperature and system monitoring are controlled by an onboard controller.
The following functions are supported:
Temperature monitoring
Measurement of the processor and the inhouse temperature by an onboard
sensor, measurement of the ambient temperature by a I²C temperature sensor.
Fan monitoring
Fans that are no longer available, blocked or sticky fans are detected.
Fan control
The fans are regulated according to temperature.
Sensor monitoring
The removal of, or a fault in, a temperature sensor is detected. Should this
happen all fans monitored by this sensor run at maximum speed, to achieve the
greatest possible protection of the hardware.
Voltage monitoring
When voltage exceeds warning level high or falls below warning level low an
alert will be generated.
System Event Log (SEL)
All monitored events of the system board are recorded in the System Event Log.
They could be retrieved after a reboot via ServerView.
