1 Safety Notes
This section provides safety precautions to follow when installing, op-
erating, and maintaining the SPARC/CPCI-52x(G). For your protec-
tion, follow all warnings and instructions found in the following text.
General
notes This Technical Reference Manual provides the necessary information
to install and handle the SPARC/CPCI-52x(G). As the product is
complex and its usage manifold, we do not guarantee that the given
information is complete. In case you need additional information, ask
your Force Computers representative.
The SPARC/CPCI-52x(G) has been designed to meet the standard
industrial safety requirements. It must not be used except in its spe-
cific area of office telecommunication industry and industrial con-
trol.
Only personnel trained by Force Computers or qualified persons in
electronics or electrical engineering are authorized to install, unin-
stall or maintain the SPARC/CPCI-52x(G). The information given in
this manual is meant to complete the knowledge of a specialist and
must not be taken as replacement for qualified personnel.
Make sure that contacts and cables of the board cannot be touched
while the board is operating.
Installation Electrostatic discharge and incorrect board installation and uninstal-
lation can damage circuits or shorten their life. Therefore:
• Before installing the board, check section 3.1.1 “Requirements”
on page 14.
• Before touching integrated circuits, ensure that you are working
in an electrostatic-free environment.
• When plugging the board in or removing it, do not press on the
front panel but use the handles.
• Before installing or uninstalling the board, read section 3 “Instal-
lation” on page 11.
• Before installing or uninstalling an additional device or module,
read the respective documentation.

Page 2 SPARC/CPCI-52x(G)
• Ensure that the board is connected to the CompactPCI back-
plane via both the J1 and the J2 connectors and that power is
available on both CompactPCI connectors.
Operation • While operating the board ensure that the power and environ-
mental requirements as given in table 4 “Maximum power supply
values without UPA64S card and PMC modules” on page 15 and
table 5 “Environmental requirements of the
SPARC/CPCI-52x(G)” on page 15 are met.
• When operating the board in areas of strong electromagnetic
radiation ensure that the board is bolted on the CompactPCI
rack and shielded by closed housing.
EMC • If boards are integrated into open systems, always cover empty
slots.
Expansion • Check the total power consumption of all components installed
(see the technical specification of the respective components). For
the total power consumption of the SPARC/CPCI-52x(G), see
table 4 “Maximum power supply values without UPA64S card
and PMC modules” on page 15.
• Ensure that any individual output current of any source stays
within its acceptable limits (see the technical specification of the
respective source).
• Only replace components or system parts with those recom-
mended by Force Computers. In case you use components other
than those recommended by Force Computers, you are fully
responsible for the impact on EMI and the eventually changed
functionality of the product.
Battery
change If a Lithium battery on the board has to be exchanged, observe the
following safety notes:
• Incorrect exchange of Lithium batteries can result in a hazardous
explosion.
• Always use the same type of Lithium battery as is already
installed.
Protect your
environment Always dispose used batteries and/or old boards according to your
country’s legislation.

Safety Notes
SPARC/CPCI-52x(G) Page 3
RJ-45
connector An RJ-45 connector is available on the board. Take into account that
the RJ-45 connector type is used for telephone connectors and for
twisted pair Ethernet (TPE) connectors. Note that mismatching these
2 connectors may destroy your telephone as well as your
SPARC/CPCI-52x(G). Therefore:
• Make sure that TPE connectors near your working area are
clearly marked as network connectors.
• Make sure that TPE bushing of the system is connected only to
safety extra low voltage (SELV) circuits.
• Verify that the length of the electric cable connected to a TPE
bushing does not exceed 1 kilometer outside the building.
• If in doubt, ask your system administrator.
