          |               MISCELLANEOUS TECHNICAL NOTES                |
          |------------------------------------------------------------|
          | To prevent power interruptions affecting data held in      |
          | controller’s 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.                      |
