                       MISCELLANEOUS TECHNICAL NOTES

  To prevent power interruptions affecting data held in controllers
  cache, it is recommended that you connect an attached battery back-up
  or an uninterruptible power supply. Also, terminating drive buses by
  installing on-board resistors is not recommended because the end drive
  on the bus cannot be removed during a "hot swap" without leaving the
  bus unterminated.
