A high (open) at pin 28 sets the drive as a Slave. - When the jumper is omitted at position E, master/slave selection is accomplished via JP1, position DD (DRIVE is MASTER Option). ********************************************************************** I N S T A L L ********************************************************************** MICROPL. 4525/4540/4550A JUMPER SETTING Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | | +-----+ +-----+ | +--+ +--+ The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mounting holes by more than 0.156 inches. Screws that are too long may short to PCBA components. The 45x0A drive uses industry-standard mounting for 3.5-inch, 1-inch high, disk drives. Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. No matter what the mounting orientation is used, Micropolis specifies the maximum allowable HDA casting temperatur to be 60*C (140*F).
