There may only be one TPE Adapter Card per system, and it must be placed at one end of the chain. All other cards on the chain must be Expansion Hubs. The Expansion Hub may be identified by the chips installed on the board. The only chip pictured in this diagram that is on the Expansion Hub is the largest of them in the upper-left hand corner.
