Power Considerations

System Power
The considerations presented in the ensuing chapters must be taken into account by system
integrators when specifying the CP6003-RA/RC system environment.
5.1.1
CP6003-RA/RC Baseboard
The CP6003-RA/RC baseboard itself has been designed for optimal power input and distribu-
tion. Still it is necessary to observe certain criteria essential for application stability and reliability.
The table below indicates the absolute maximum input voltage ratings that must not be exceed-
ed. Power supplies to be used with the CP6003-RA/RC should be carefully tested to ensure
compliance with these ratings.
Table 5-1:
Maximum Input Power Voltage Limits
SUPPLY VOLTAGE
+3.3 V
+5 V
+12 V
-12 V
Warning!
The maximum permitted voltage indicated in the table above must not be
exceeded. Failure to comply with the above may result in damage to your
board.
The following table specifies the ranges for the different input power voltages within which the
board is functional. The CP6003-RA/RC is not guaranteed to function if the board is not
operated within the prescribed limits.

INPUT SUPPLY VOLTAGE

5.1.2
Backplane
Backplanes to be used with the CP6003-RA/RC must be adequately specified. The backplane
must provide optimal power distribution for the +3.3 V, +5 V and +12 V power inputs.
Input power connections to the backplane itself should be carefully specified to ensure a mini-
mum of power loss and to guarantee operational stability. Long input lines, under-dimensioned
cabling or bridges, high resistance connections, etc. must be avoided. It is recommended to
use POSITRONIC or M-type connector backplanes and power supplies where possible.
