PENT/CPCI-721 xxi
RJ-45 Connector
An RJ-45 connector is used for both telephone and twisted pair Ether-
net (TPE) connectors. Mismatching the two connectors may destroy
your telephone as well as your PENT/CPCI-721. Therefore:
• TPE connectors near your working area have to be clearly marked
as network connectors.
• TPE bushing of the system has to be connected only to safety extra
low voltages (SELV) circuits.
• The length of the electric cable connected to a TPE bushing must
not exceed 100 meter.
Battery
If a Lithium battery on the board has to be exchanged, observe the fol-
lowing 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.
• Exchange the battery before five years of actual use have elapsed.
• Exchanging the battery always results in a loss of data. Therefore,
back up affected data before exchanging the battery.
• When installing the new battery, ensure that the ’+’ on top of the
battery stays at the top and therefore is visible when viewing the
board from its component side.
Environment
Always dispose of used batteries and/or old boards according to your
country’s legislation.
CompactPCI
The PENT/CPCI-721 is a system slot board, i.e. it always has to be
operated in the system slot of the CompactPCI rack. The I/O-721 is a
peripheral slot board, i.e. it always has to be plugged into peripheral
slots of the CompactPCI rack. Otherwise the boards and other cards
in the system may be damaged.
