JP3 Auto Power Save -------------------- The function is selected by inserting a short-circuiting plug in JP3. Short-circuiting plug present: Auto power save on. Short-circuiting plug not present: Auto power save off. ********************************************************************** I N S T A L L ********************************************************************** NEC D3835/3855/3856/3865 INSTALLATION GUIDE DEC. 92 NOTES ON INSTALLATION ===================== First install the drive with the components side to the bottom. Connect the system power and interface cables to the drive connectors. Both connectors are keyed and can only be connected one way. The interface connector may not be keyed. In this case check if the red edge of the interface cable is connected to the pin 1 of the drive connector. After installing the hardware please turn on your computer system and run the setup program. The setup setting is "drive not installed". The SCSI interface accepts up to seven drives. For a dual or more drives installation set the SCSI ID. In order to install DOS please run the DOS program FDISK and Format C:/s. In case of installation trouble please contact NEC hotline: Tel. 49/89/93006 708 Caution: SCSI drives don't need a low level format. If a new low level format become neccessary, please run only qualified programs for SCSI devices or the internal low level program of SCSI host adapters (i.e. Adaptec AHA1540). ********************************************************************** F E A T U R E S ********************************************************************** NEC D3835/3855/3856/3865 INSTALLATION GUIDE DEC. 92 NEC drives ----------- The NEC IDE/SCSI drives are designed to work in the IBM AT and compatible systems and gurantee the operation with any standard IDE and SCSI Controller. Further, the NEC drives provide compatibility to the ATA/SCSI CAM and ANSI (X3-131-199x) standard as well as to all known operating systems.
