Technical Information:
Each DCC unit has minimum one Power In card. The card definitely must not be removed
from its slot while the system is ON. The DCC Power In card is plugged in the rightmost slot.
If redundant of this card is available, redundant card should be installed into the leftside (slot
number 0) of the DCC Power In card. Normally, this slot is used for DCC 8E1 Interface
cards. When redundant DCC Power In card is installed, number of DCC 8E1 Interface cards
to be installed is decreased by 1 and equal to 13. When redundant DCC Power In card is
installed into the system, system will go on operating without any problem in case any
problem occurs at master DCC Power In Card.
Operational Information:
The LEDs sign3V3 and +1V5 statuses are supposed to be continuously ON during
the normal operation of the system, whereas all the other LEDs are supposed to be OFF. In
case the LED statuses are different from what have been specified here, the system should
be checked.
