A file system includes a processing device that processes first data with at least one of a copying function to read image data of an original document and record the read image data on a sheet, a transmitting function to send and receive image data andor character data via a communication line, and a recording function to record received image data andor character data on a sheet. Thereafter, forwarding records of local routing instances between the at least two aggregation devices are synchronized to enable one aggregation device to support data traffic for the other aggregation device if it has failed or a link to the aggregation device has failed. The semiconductor die assembly may be configured in a package with leads extending from two sides thereof, such as a thin small outline package, or four sides thereof, such as a quad flat pack.
