When open => pull-up, normal spin-up at POR. Cable Selection --------------- Using Cable Selection, the drive address depends on the condition of pin 28 of the AT interface cable. In the case when pin 28 is ground or low, the drive is a Master. If pin 28 is open or high level, the drive is a Slave. Cabling ------- The maximum cable length from the host system to the HDD plus circuit pattern in the host system shall not exceed 18 inches. AT Signal Connector ------------------- The AT signal connector is designed to mate with Dupont part number 69764-044 or equivalent. ********************************************************************** I N S T A L L ********************************************************************** IBM DDLA-21215/21620 NOTES ON INSTALLATION Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa. The drive must be securely mounted in the system to prevent motion or vibration during a seek operation or spindle rotation using appropriate screws or equivalent mounting hardware. The recommended mounting screw torque is 3.0 0.5 kgf.cm. The recommended mounting screw depth is 3.0 0.3mm for bottom and 3.5 0.5mm for horizontal mounting. I/O Connector ------------- PIN 39 = -DASP PIN 41 = +5V LOGIC PWR PIN 42 = +5V MOTOR PWR PIN 43 = GND PIN 44 = RESERVED There are two input pins for +5 Volt power supply, "+5V LOGIC" and "+5V MOTOR". +5V LOGIC is connected to the internal logic circuits and +5V MOTOR is connected to the spindle motor and motor driver. It is possible to turn on and off +5V LOGIC by an external switch circuit to reduce power consumption to the least possible. In this mode, a voltage drop out due to the motor spin up current can be reduced by connecting +5V MOTOR line into the system power source directly. If the above power management option is used, all signal lines that will be electrically active in the host system while the HDD is disconnected from power line shall be isolated by Three-State line drivers. Internal leakage through ESD protection circuit may pull down LPUL (Least Positive Up Level) of Logic signal. Use both lines in parallel, for regular HDD applications. Air Cooling Requirement ----------------------- The host system must provide sufficient air flow across the drive to maintain the temperature at less than 60*C (measured at the centre of the files top cover).
