MISCELLANEOUS TECHNICAL NOTES

To prevent power interruptions affecting data held in controllerís 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.
