Only replace or expand components or system parts with those recom-
mended by Motorola. Otherwise, you are fully responsible for the impact
on EMC and the possibly changed functionality of the product.
Check the total power consumption of all components installed (see the
technical specification of the respective components). Ensure that any
individual output current of any source stays within its acceptable limits
(see the technical specification of the respective source).
If more than two IDE devices are connected to the IDE bus, the bus is not
able to recognize all of the devices and the RTB might not start correctly.
Therefore, only connect up to two devices to the secondary EIDE inter-
face on the RTB.
If the secondary EIDE interface on the RTB is connected to an external
device the PENT/CPCI-735R2/736R2 is hot-swappable but data may get
lost. Therefore, always save data on disk before installing or removing
the base board under hot-swap conditions.
The RTB provides several RJ-45 connectors which commonly serve as
different interfaces (RS-485, twisted pair Ethernet and telephone). Con-
necting different interfaces (e.g. Ethernet and RS-485) may damage the
board. Therefore, make sure that you only connect matching interfaces.
Furthermore, take note of the following:
• Clearly mark TPE connectors near your working area as network con-
nectors.
• Connect TPE bushing of the system to safety extra low voltages
(SELV) circuits only.
• Make sure that the length of the electric cable connected to a TPE
bushing does not exceed 100 meter.
Always dispose of old boards according to your country's legislation, if
possible always in an environmentally acceptable way.
