Hitachi Global Storage Technologies Connectors Pin 1 Pin A AT I/F Connector Jumper Power Block Connector The DC power connector is designed to mate with AMP p/n 1-80424-0 using AMP strip pins (p/n 350078-4), loose piece pins (p/n 61173-4), or their equivalents. Note: The AT signal connector is a 40-pin connector. Cabling The length of the cable from the host system to the drive must not exceed 18 inches. For systems operating with Ultra DMA mode 3, 4, or 5, the 80-conductor ATA cable assembly must be used. Jumper block Jumper pin letter designations I GECA H F DB A jumper attaches two pins together to configure the drive for the proper mode of operation. Jumper settings 16 head logical architecture Master active* A-B and G-H Slave active A-B and C-D Cable Select A-B and E-F Master/Slave present E-F and G-H Reserved I 15 head logical architecture Master active A-C and G-H Slave active A-C Cable select A-C and E-F Master/Slave present A-C, E-F & G-H Reserved I All other jumper settings are reserved. Do not make other settings! *Shipping default DC power requirements Damage to the drive electronics may result if the power supply cable is connected or disconnected while the power is on. There is no special power on/off sequencing required. The following voltage specification is applied at the power connector of the drive.
