                       MISCELLANEOUS TECHNICAL NOTE

  Unused daisy-chain connectors must be terminated with a provided
  termination block. 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.
