J2 LED ------ When a LED is connected to the +LED and -LED pins on J2, that LED functions in the same manner as the LED which is mounted on the disk drive's faceplate. This is typically used in cases where the drive is positioned with the LED not visible and the faceplate removed. J6 Spindle Synchronization Control Option ------------------------------------------ -----+-J6-+-PCB---+---------+--- |3 1| | J2 | |4 2| | | +----+ +---------+ Pin 1 = Gnd Pin 2 = Master Sync Pin 3 = Reserved Pin 4 = Slave Sync This feature allows multiple drives to synchronize the angular position of their spindles such that their INDEX signals line up to within 40 microseconds of each other. The drives are connected together with a twisted pair cable to connectpins 1 through 4 of J6 to the same pins of all the other drives that can be locked together. This cable can optionally be connected to a 60 Hertz system clock. The spindles are synchronized with a once per revolution pulse on the SLAVE SYNC pin (pin 4 of J6). Note: The configuration of J6 is the same for all PCB fabrications. Rotational Position Locking (RPL) --------------------------------- The Rotational Position Locking (RPL) and Rotational Offset fields in Mode Select Page 4 are used to control the spindle synchronization. The two bits of the RPL field select one of four modes for rotational position locking. +-----+------------------------------------------------------------+ | RPL | Mode | +-----+------------------------------------------------------------+ | 00b | Indicates that spindle synchronization is disabled | | 01b | The drive operates as a synchronized-spindle slave | | 10b | The drive operates as a synchronized-spindle master | | 11b | The drive operates as a synchronized-spindle master control| +-----+------------------------------------------------------------+ With 00b in the RPL field the drive spindle will be unsynchronized. The unsynchronized drive will not output on the SLAVE SYNC or MASTER SYNC pins. It will ignore pilses on the SLAVE SYNC pin. The default is the UNSYNCHRONIZED mode. A drive operating as a slave synchronizes its INDEX to the pulse on the SLAVE SYNC pin. The drive synchronizes the first edge of the INDEX pulse to the rising edge of the SLAVE SYNC pulse. SLAVE SYNC is an open collector TTL signal with a frequency of 60 Hertz 0.25%. A slave has 01b in the RPL field. The one pulse per revolution on the SLAVE SYNC can come directly from a drive configured to be a master. The master drive spins autonom- ously and outputs a pulse which concides with its INDEX on pin 4 of J6. There must only be one master on the cable. A master has 10b in the RPL field. A drive can provide a 60 Hertz signal on the MASTER SYNC pin (pin 2 of J6). A drive configured to do this is in the MASTER CONTROL mode with 11b in the RPL field. Another device can buffer this signal and transmit it on the SLAVE SYNC pin. A drive in the MASTER CONTROL mode synchronizes its INDEX to SLAVE SYNC pulses received independent of the pulses it output on the MASTER SYNC pin. JP5/JP6 Termination ------------------- The master synchronization and slave synchronization wires are driven by the drives with open collector drivers. These drivers can sink over 300 milliamps, allowing both ends of the cable to be terminated with pull up resistors to +5 volts DC. For best results, terminate both of the cable with the characteristic impedance of the cable connected to +5 volts DC. Jumper JP5 will connect slave synchroniza- tion to a 150 ohm resistor to +5 volts DC. Jumper JP6 will connect master synchronization to a 150 ohm resistor to +5 volts DC. Power-up Sequencing ------------------- When a drive is commanded to be a slave, it checks the frequency of the SLAVE SYNC pulses before it synchronizes to it. In a system of drives, SLAVE SYNC pulses should be present before drives are commanded to be slaves. This can be done by commanding a ready drive to be a master, or the controller can generate SLAVE SYNC. The controller may also command a drive to be a master control and buffer the received MASTER SYNC pulses. JP1/JP12 Drive Power-Up Options -------------------------------- Note: This section only applies to drives with the Common Fabrication PCB. All other drives will, by default, start when power is applied. +-------+-------+--------------------------------+ | JP1 | JP12 | Mode | +-------+-------+--------------------------------+ | OPEN | OPEN | Start by ID sequence | | OPEN | CLOSED| Start after 11-13 second delay | | CLOSED| OPEN | Wait for START command | |xCLOSED| CLOSED| Start when power is applied | +-------+-------+--------------------------------+ In order to allow for system power supply constraints, which may require minimizing surge current when powering up multiple disk drives, four modes of start-up sequencing are provided. Start by ID sequence The disk drive delays spinup for approximately 11 to 13 seconds multiplied by the SCSI ID. This allows power-up sequencing. Start after 11-13 second delay The disk drive delays spinup for approximately 11 to 13 seconds. Wait for START command The disk drives does not spinup until the initiator issues a START STOP UNIT command with the start bit equal to one. Start when power is applied The motor starts as soon as power is applied. JP10/JP11 Terminator Power Selection ------------------------------------- JP10 CLOSED Terminator power is external, from the SCSI bus. JP11 OPEN x JP11 CLOSED Terminator power is internal, from the drive. JP10 OPEN JP10 CLOSED Terminator power is provided from the JP11 CLOSED drive and to the SCSI bus. Hence, the drive is at one end of the SCSI bus with terminators in place and id also supplying terminator power for the device at the other end of the SCSI bus. J2 Pin 7-8/JP2 Write Protect Option ------------------------------------ The write protect jumper is JP2 for the original fabrication PCB. For the common fabrication OCB the write protect jumper is on pins 7 and 8 of connector J2. J2/JP2 CLOSED Data cannot be written to the drive; only READ operations can be executed. x OPEN Allowing normal reading/writing. J2 Pins 3-4/JP13 Parity Option ------------------------------- The parity jumper is on pins 3 and 4 of connector J2 for the original fabrication PCB. For the common fabrication PCB the parity jumper is JP13. x J2/JP13 OPEN Enables odd parity detection in the drive. CLOSED Disables odd parity detection in the drive. Odd parity is always generated by the drive and provided to the SCSI bus. Other Jumpers ------------- Other jumper positions not shown or not described herein are not user selectable. These jumpers are for factory use only. Improper operation may occur if non-user jumpers are changed.

Mounting -------- The drive may be mounted on any axis. In any final mounting configuration, ensure that the operation of the three shock mounts which isolate the base casting from the frame is not restricted. Certain switching power suppplies may emanate electrical noise, which can degrade the specified read error rate. For best results, orient the drive so that the PCB assembly is not adjacent to these noise sources. Eight mounting holes, four on the bottom and two on each side, are provided for mounting the drive into an enclosure. The size and location of these holes are identical to industry standard floppy drives. Caution: The casting is very close to the frame mounting holes in some locations. Mounting screws lengths must be chosen such that no more than 0.125 inch of the screw is available to enter the frame mounting hole. The torque applied to the mounting screws must be between 9 and 12 inch pounds. Installation Requirements ------------------------- The Panther SCSI disk drive must operate in a temperature range be- tween 50*F and 122*F (10*C and 50*C). The drive should be installed in applications where temperature extremes outside of this range are avoided. To maintain proper operating temperature, the Panther SCSI disk drive must be mounted in such a way as to ensure adequate airflow across the PCB. Caution: These requirements must be met to ensure proper functioning of the drive. If they are not met, data loss and/or permanent damage to the drive will result. J1 SCSI Connector ----------------- Connection to J1 is via a non-shielded fifty-pin connector, consisting of two rows of twenty-five female contacts on 0.1 inch centers. Recommended strain-relief connectors are AMP part-number 1-499506-2, or Dupont part number 669002 (66900-250). Use of a keyed connector is recommended. J2 Auxiliary Connector (Jumper Bank) ------------------------------------ Connector J2 is an auxiliary connector providing remote or local control of SCSI ID, and the ability to carry the LED signal beyond the drive. The auxiliary connector is a Berg 68451-121, ten-pin part. The mating connector is a 3M 3473-6010 part. J3 Power Connector ------------------ The four-pin DC power connector J3 is similar to AMP's MATE-N-LOCK connector, part number 350542-1. J3 however, is surface mounted to the PCB rather than free-hanging as the AMP part is. The recommended socket housing that is compatible with connector J3 is AMP part number 1-480424-0. The recommended female socket part numbers 350078-4 (strip) or 61173-4 (loose piece). J4 Ground Tab ------------- The DC ground connector is a Faston-type connector, AMP part number 61761-2. The recommended mating connector is AMP part number 62187-1. If wire is used, the hole in J4 will accommodate a maximum wire size of 18 AWG. This wire should be grounded to the AC ground or to the metal of the computer frame. Sector Size ----------- The drive is shipped from the factory formatted with 512 byte sectors. Configuration parameters are default values in all optional cases. It is recommended that users reformat the drive with the user's sector size, using the Plist and the user's configuration parameters. Interface Termination --------------------- SCSI devices require proper interface termination. The first device and the last device on the daisy chain SCSI bus must be terminated. Remove the terminating resistor networks from any devices in between. For instance, if the drive is in the middle of the string, remove its terminators. The devices driving the drive inputs should be open collector devices capable of sinking at least 48 milliamps at a voltage level of less than 0.5 volts DC (7438 or equivalent). Deviices receiving the drive inputs should be SCHMITT trigger type to improve noise immunity; 74LS14, 74LS240, or equivalent. The initiator should not load bus with more than one standard low power Schottky transistor-transistor (LSTTL) input load per line. Single Ended signal Termination ------------------------------- Single ended operation is the mode of operation that is standard for all Panther SCSI disk drives. To terminate a drive with the original fabrication PCB, install resistor networks in locations RN8, RN6 and RN3. To terminate a drive with the common fabrication PCB, install resistor networks in locations RN14, RN10 and RN5. As shipped (for single ended operation) interface signal lines are terminated with three removable 220/330 ohm resistor network packs. If for some reason you need to order these resistor network packs, please call Maxtor Technical Support at 800-856-5333. Differential Signal Termination ------------------------------- Differential operation is available only as an option ordered from the factory. It comes only on the Panther P1 with the common fabrication PCB and is known as the P1-17DS. To terminate this drive, install resistor networks in locations RN12, RN8, RN3, RN13, RN9 and RN4. As shipped (for differential operation) interface signal lines are terminated with six removable 330/150/330 ohm resistor network packs. Removable Faceplate ------------------- The faceplate may be removed in installations where it is not required. Remove the two e-clips and unplug the LED cable from the PCB. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR PANTHER SCSI QUICK REFERENCE MANUAL 1027601 REV.
