2 Important notes
In this chapter you will find essential information regarding safety when working
with the system board.
VCAUTION!
With the system board installed you must open the system to access the
system board. How to access the system board of your system is
described in the appropriate service supplement.
When handling the system board, refer to the specific notes on safety in
the operating manual and/or service supplement for the respective
server.
2.1 Notes on safety
VCAUTION!
●The actions described in these instructions should only be performed
by authorized, qualified personnel. Equipment repairs should only be
performed by qualified staff. Any failure to observe the guidelines in
this manual, and any unauthorized openings and improper repairs
could expose the user to risks (electric shock, fire hazards) and could
also damage the equipment. Please note that any unauthorized
openings of the device will result in the invalidation of the warranty
and exclusion from all liability.
●Transport the device only in the antistatic original packaging or in
packaging that protects it from knocks and jolts.
●Only install expansions that are allowed for the system board. If you
install other expansions, you may damage the requirements and rules
governing safety and electromagnetic compatibility or your system.
Information on which system expansions are suitable can be
obtained from the customer service centre or your sales outlet.
●The warranty expires if the device is damaged during the installation
or replacement of system expansions.

Notes on safety Important notes
VCAUTION!
●Components can become very hot during operation. Ensure you do
not touch components when making extensions to the system board.
There is a danger of burns!
●Transmission lines to peripheral devices must be adequately
shielded.
●To the LAN wiring the requirements apply in accordance with the
standards EN 50173 and EN 50174-1/2. As minimum requirement
the use of a protected LAN line of category 5 for 10/100 MBps
Ethernet, and/or of category 5e for Gigabit Ethernet is considered.
The requirements of the specification ISO/IEC 11801 are to be
considered.
●Never connect or disconnect data transmission lines during a storm
(lightning hazard).
Batteries
VCAUTION!
●Incorrect replacement of lithium battery may lead to a risk of
explosion. The batteries may only be replaced with identical batteries
or with a type recommended by the manufacturer.
It is essential to observe the instructions in chapter “Replacing the
lithium battery”.
Modules with electrostatic-sensitive components
Boards with electrostatic sensitive devices (ESD) are marked with the following
label:
Figure 1: ESD label

D2785 (TX120 S2) Technical Manual 9
Important notes Notes on safety
When you handle components fitted with ESDs, you must observe the following
points under all circumstances:
●You must always discharge yourself of static charges (e.g. by touching a
grounded object) before working.
●The equipment and tools you use must be free of static charges.
●Shut-down the system and remove the power plug from the power socket
before inserting or removing boards containing ESDs.
●Always hold boards with ESDs by their edges.
●Never touch pins or conductors on boards fitted with ESDs.
●Use a grounding cable designed for this purpose to connect yourself to the
system unit as you install/deinstall the board.
●Place all components on a static-safe base.
IYou will find a detailed description for handling ESD components in the
relevant European or international standards (EN 61340-5-1,
ANSI/ESD S20.20).
Notes about boards
●During installation/deinstallation of the board, observe the specific instruc-
tions described in the service supplement for the respective server.
●Shut-down the system and remove the power plug from the power socket
before you make modifications on an installed board.
●To prevent damage to the board, the components and conductors on it,
please take great care when you insert or remove boards. Take great care
to ensure that extension boards are slotted in straight, without damaging
components or conductors on the board, or any other components, for
example EMI spring contacts
●Be careful with the locking mechanisms (catches, centring pins etc.) when
you replace the system board or components on it, for example memory
modules or processors.
●Never use sharp objects (screw drivers) for leverage.

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.
