[. . . ] Conner Filepro Performance Series CFP1060E/CFP1060S/CFP1060W Intelligent Disk Drive Product Manual Revision A May 1994 3081 Zanker Road San Jose, CA 95134-2128 (408) 456-4500 FCC Notice This equipment generates and uses radio frequency energy and, if not installed and used properly; that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment on and off, you are encouraged to try to correct the interference by one or more of the following measures: · · · Reorient the receiving antenna. [. . . ] Delaying Spin Up at Power On - CFP1060S A jumper in the E6 location, delays spin up on power-up by the value of the drive's SCSI ID multiplied by 4 seconds (i. e. Delaying spin up on application of power can also be enabled by setting the SDLY bit in MODE SELECT page 00H (Operating Parameters). Refer to the Ninth Generation SCSI Technical Reference Manual for additional information regarding the MODE SELECT command. Refer to Figure 4-3 for the location of the Delayed Spin jumper, E6.

Installing the jumper will cause the drive to ignore SCSI bus Parity In but it will continue to generate SCSI bus Parity Out. Disabling SCSI Bus Terminator Power (TERMPWR) - CFP1060S Power to the on-board terminators is provided by the higher of the voltage supplied at Pin #26, J2 or the voltage level at the 5 Volt power input to the drive minus one diode drop. Termination Power to external terminators can be supplied by the drive through Pin #26, J2. The signal output characteristics are described in chapter 5. The TERMPWR line can be disconnected from the drive by removing Jumper E8.

Page 36 Filepro CFP1060E/CFP1060S/CFP1060W SCSI Physical Characteristics Chapter 4 Setting the Bus Termination - CFP1060S This drive provides on-board Alternative 2 active termination for the SCSI bus. The termination resistors, which are contained in two Single Inline Packs (SIPs) should be removed from the drive unless it is a SCSI device at the physical end of the bus. Figure 4-4 shows the location of the terminator resistors. Figure 4-4 Terminator Resistor Locations Remove to Disable TERMPWR Input/Output SCSI Terminators. Remove in all but the last drive in the chain J1 J2 E8 F1 J3 SS LED J4 J6 100_4_2 TERMPWR Fuse NOTE: The TERMPWR output of the drive is protected by a 1 Ampere fuse. If external terminators are being powered from the drive and SCSI bus problems are suspected, verify that the fuse is still operational using a meter. Technical Reference Manual Page 37 Chapter 4 SCSI Physical Characteristics Cabling the Drive - CFP1060S Connect the SCSI interface cable and the spindle synchronization cable (when needed) as shown in Figure 4-5. Figure 4-5 Connecting the cabling J1 J2 50-pin SCSI Interface E8 Spindle Synchronization Connection J3 SS LED Key Pin 1 (typically indicated by a colored stripe on the cable J4 J6 Pin 1 4-pin Power Connector 100_4_3 SCSI Bus Cable The cable and mating connector required to connect the drive to the SCSI bus are described in Chapter 5. In addition, the cable should meet the following guidelines, particularly with FAST SCSI-2 systems: · · · · · · Do not route the data cable next to the drive PCB or any other high frequency or large current switching signals. Improper drive operation can result from improper cable routing. Cable stubs should not exceed 0. 1 meter (4 inches). There should be 0. 3 meters (12 inches) of cable between drives. The total cable length should not exceed 6 meters (20 feet) and may have to be reduced if a mixture of round and flat cable are used. Do not tightly bundle excess flat cable against each other since this promotes cross coupling of signals on the cable. Use spacers to maintain a minimum of 0. 050 inches (1. 27mm) gap between cable runs. Do not clamp the cable tightly against a metal chassis since this will degrade the signal. [. . . ] Track Skew Factor: Defines the number of physical sectors between the last logical block of one track, and the first logical block on the next sequential track of the same cylinder. Cylinder Skew Factor: Specifies the number of physical sectors between the last logical block of one cylinder and the first logical block on the next sequential cylinder. SSEC (Soft Sector Format): Set to zero to indicate the drive does not support a soft sector format. HSEC (Hard Sector Format): Set to one to indicate the drive supports a hard sector format. [. . . ]
