Con sult the driv e manual for the proper setting s. Install new hard drive s into t he UltraT rak100 by doing the follow ing: 1.
5 C ONNECTING THE SCSI C ABL ES Installa tion of t he UltraTrak10 0 disk array is very simi lar to th e instal lation of a standard SCSI drive. The SCS I connector accept s the standa rd 68-pin LVD SC SI connect or used on most LVD SCSI device s .
