A communication system has multiple communication buses and multiple bus controller cards each supplying at least two independent channels of communication between one or more hosts and the communication buses. One of the controller cards is designated as a primary controller card for managing the communication buses and resetting the communication buses such that if a controller card is inserted to or removed from the system then the buses are reset.

Bus reset management by a primary controller card of multiple controller cards

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.
