SHUTDOWN PROCEDURE in Section 4 to shutdown the INESM01 module. Push and turn the two front panel captive retaining latches ½-turn to unlatch the INDDM01 module. It is unlatched when the slots on the latches are vertical and the open end of the slots faces away from the module. Slide the module out of its module mounting unit back- plane connector so that power is removed from the module. The INSCS01 and INESM01 modules may need to be partially pulled forward to ease removal of the hard disk drive and floppy disk drive ribbon cables. If so, push and turn the two front panel captive retaining latches turn to unlatch the modules and partially pull them forward as needed. Remove the ribbon cable from the P connector on the SCSI adapter board (directly behind the module faceplate). 6. Remove the ribbon cables from the P and P connectors on the INESM01 module. Slide the disk drive module out of the module mounting unit. The disk drive module is shipped with the required ribbon cables attached to the module. Partially insert the disk drive module into its module mounting unit slot. Connect the ribbon cable from the P connector on the INDDM01 module to the P connector on the INESM01 module. Connect the ribbon cable from the P connector on the INDDM01 module to the P connector on the INESM01 module. Slide the INDDM01 and INESM01 modules into the mounting slots. Replace the ribbon cable from the INSCS01 module to the P3 connector on the SCSI adapter board. Push and turn the front panel captive latches turn to lock the modules in place.
