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. [. . . ] A receptacle connector Amp P/N 111622-1 or equivalent can be used to connect a ribbon cable to this header. Table 4-6 defines the relationship between the jumpers and the SCSI ID:

Disabling Spin-Up at Power On - CFP1060S A jumper in the E5 location, disables spin up after power-on for applications where spin up sequencing is necessary. An optional 2mm pin pitch right angle header is located on the front of the PCBA (opposite the SCSI interface connector) which can alternatively be used to disable spin up. Disabling spin up on application of power can also be enabled by setting the DSPN bit in MODE SELECT page 00H (Operating Parameters). The Host must issue a START UNIT command to cause the drive to spin up. Refer to the Ninth Generation SCSI Technical Reference Manual for additional information regarding the MODE SELECT and START/STOP UNIT commands. Refer to Figure 4-3 for the location of the Disable Spin jumper, E5 or 0E5.

SCSI Physical Characteristics
Disabling the SCSI Bus Parity - CFP1060S SCSI parity is always enabled in both directions, unless the E7 Parity disable jumper is installed. 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 TERMPWR line can be disconnected from the drive by removing Jumper E8.

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.

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.

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. 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. [. . . ] The value reported for the number of sectors per track is dependent on the active notch value. Data Bytes Per Physical Sector: Defines the number of data bytes per physical sector. 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. [. . . ]
