A network router having an internal automated backup is provided. Specifically,
the present invention provides a network router having at least one primary port
facility, a switched fabric, and a backup card array. When a router card connected
to a primary port facility fails, a failure message is automatically sent to the
switched fabric. The switched fabric then disconnects the failed card from the
primary port facility and places it in an extended bay. Thereafter, the switched
fabric connects a backup router card from the backup card array to the primary
port facility. In addition, the primary port facilities under the present invention
can include a primary and a secondary processor for more reliable communication.
