| 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. |
