Abstract
A communication system with a plurality of interface slots includes control logic for determining and designating the status of one or more controller cards inserted in one of the slots such that: a controller card is designated as the primary card if it is inserted in an interface slot while the other slots are empty; a controller card in an interface slot with primary status retains its primary status while other controller cards are added or removed from the system; a controller card in an interface slot with a non-primary status assumes primary status if the controller card with non-primary status is plugged in a slot that after a power interruption is designated as the slot to assume primary status, or the controller card with primary status is removed from the system.
