A blower having a fan mounted perpendicularly relative to an airflow discharge port. Placement of the source and macros with the sinks is pre-designed and buffers are placed in branches connecting the source with the multiple sinks. A method for ensuring compatibility is disclosed comprising determining when the BOSS node is idle, determining whether the last packet transmitted by any border node was an Alpha format packet if the BOSS node is idle, and unlocking the Legacy cloud if the last packet transmitted by the border node was not an Alpha format packet.
