♦ When installing PCBs in the DK424i cabinets, all PCBs must be installed in the same order in relation
to each other as they were in the DK424 cabinets. You may have to skip slots in the new cabinets to
place RDTU PCBs into the allowed slots.
♦ Only install the PCBs that currently exist in the DK424 cabinets into the DK424i cabinets – do not add
more line or station PCBs during the upgrade. The only exception to this rule is that you can add an
RSIU, PIOU, PIOUS, RSSU.
