C 12/83 Jumper Setting ============== Drive Select ------------ Five jumpers are provided for logical drive number assignment. DS1, DS2, DS3, DS4 cause the drive to be selected when the active drive select line matches the installed jumper. Jumper A, when installed, causes the drive to be selected constantly. The Quantum part number for the jumper plug is 22-10036. +-------+----------------------------+ |Drive | Jumper | |Select | 1 2 3 4 | +-------+-------+------+------+------+ | 1 | CLOSED|OPEN |OPEN |OPEN | +-------+-------+------+------+------+ | 2 | OPEN |CLOSED|OPEN |OPEN | +-------+-------+------+------+------+ | 3 | OPEN |OPEN |CLOSED|OPEN | +-------+-------+------+------+------+ | 4 | OPEN |OPEN |OPEN |CLOSED| +-------+-------+------+------+------+ Control Cable Termination ------------------------- If the Model Q2000 is the last drive at the end of the control signal cable, a 220/330 ohm terminator pack must be installed. The terminator must be removed if the drive is not at the end of a string of drives. The Quantum part number for the terminator pack is 13-12302. Minus Power Selection --------------------- The Model Q2000 requires - 5 VDC but will regulate greater negative voltages between -7 VDC and -16VDC. A jumper plug is supplied at Control PCB (Minus Voltage Select) that allows the user too select which negative voltage will be supplied to the drive. The drive is shipped with the jumper in the -15 VDC position. If the user is suppyling -5 VDC, the jumper should be moved to the -5V position. CAUTION Damage to components that use -5VDC can occur if the jumper is in the -5V position and greater negative voltages are applied to the drive. RE-ZERO Select -------------- The Model Q2000 can be re-calibrated to track 000 by driving a single control line. If use of this re-zero function is desired, jumper C should be installed, this allow J1 pin 6 to be used to initiate the re-zero function. Pulsing the Rezero line will cause the micropro- cessor to reset, forcing the drive into its power up recalibration sequence which takes 10 seconds typically. Radial Seek Complete Select --------------------------- The Model Q2000 can provide the output signal - Seek Complete on the data cable J2. If use of this signal is desired, Jumper D should be installed, this allows seek complete to be output at data cable J2 pin 3. This signal is not gated with drive select. Floppy write data termination ----------------------------- From the factory, this option allows for termination of the floppy write data line (J1 connector Pin 38) when the drive is the last drive of a Daisy Chain. The wire from J1 PIN 38 to the terminator must be cut if termination is not desired. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM Q2000 PRODUCT DESCRIPTION OEM MANUAL 40-30011 REV. C 12/83 Notes on Installation ===================== Space Requirements ------------------ The Series 2000 drives are shipped with a face plate installed. Mounting -------- The Series 2000 drive may be mounted in any orientation and has two mounting brackets with integral shock mounts for this purpose. CAUTION The base casting is very close to the cabinet walls. Mounting screws lengths must be chosen so that no more than .125" (3.175) of the screw is available to enter the cabinet mounting holes. This length will allow full use of the mounting hole threads and avoid damaging or placing unwanted stress on the base casting. To avoid stripping the mounting hole threads the maximum torque applied to the mounting screws must not exceed 18 inch/pounds. Mounting holes: 8-32 UNC-2B, 16 places. AC Power ------- J2 J1 J5 DC Power +--XXXXXXXXX----XXXXXXXXXXXXXXXXXX--XXXXX-+ | | | | | J4 AC Power |(AC motor drives +------------------------XXXXXX-----------+ only) | | +-----------------------------------------+ AC power and frame ground are supplied to the Series 2000 through a 3 pin connector. The pin housing (J4) is mounted in the drive and is AMP P/N 1-480701-0 with pins AMP P/N 350687-1 and 350654-1 (gnd pin). The recommended mating connector (P4) is AMP socket P/N 1-480700-0 with pins P/N 350536-1. The disk drive is shipped with DC ground (base casting) and AC ground (drive motor) connected together with a ground strap located on the drive motor and base casting. AC and DC grounds may be separated by removing the ground wire connected between the AC motor and the base casting. Additionally the bubble clamps and base casting must be isolated from the drive cabinet by insulating paper or other means. 60 Hz 50 Hz +-1----3-+ Pin 110V (Standard) 208/230V 100V 220V + X xx X + 1 90-127V 180-253V 90-127V 180/253V +---2----+ 2 FRAME GND FRAME GND FRAME GND FRAME GND 3 90-127RTN 180-253V 90-127RTN 180-253V DC Power Connector ------------------ DC power connector (J5) is a 6 pin AMP Mate-N-Lok connector P/N 380999-0 mounted on the solder side of the PCB.

Interface Connectors -------------------- Two interface cable connections are required by the Model Q2000; a control cable (J1) and a signal or data cable (J2). Connection to J1 is through a 50 pin PCB edge connector. The pins are numbered 1 through 50 with the even pins located on the component side of the PCB and odd pins located on the solder side of the PCB. Pin 2 is located on the end of the PCB connector closest to the J2 connector and is labeled. A key slot is provided between pins 4 and 6. The recommended mating connector for P1 is Scotchflex ribbon connector P/N 3415-0001. Connection to J2 is through a 20 pin PCB edge connector. The pins are numbered 1 through 20 with the even pins located on the component side of the PCB. The recommended mating connector for P2 is Scotch- flex ribbon connector P/N 3461-0001. A key slot is provided between pins 4 and 6. Ventilation ----------- The Model Q2000 operates without a cooling fan provided the ambient air temperature does not exceed 115*F (46*C). Any user designed cabinet should provide adequate air circulation so that this maximum air temperature is not exceeded. Introduction ------------ The Model Q2000 has two interface connectors: one for control signals which are TTL in nature and one for data transfer signals which are differential in nature. The control signals are both input, those originating external to the drive and output, those originating within the drive. The control signals could also be divided into two types: those intended to be multiplexed in a multi-drive system and those intended to do the multiplexing. The control signals that do the multiplexing are DRIVE SELECT 1, DRIVE SELECT 2, DRIVE SELECT 3, and DRIVE SELECT 4 which are input signals. The multiplexed signals are: STEP, DIRECTION, HEAD SELECT, WRITE GATE, REDUCE WRITE CURRENT, and REZERO input signals, TRACK 000, INDEX, READY, WRITE FAULT and SEEK COMPLETE output signals. Up to four drives may be connected in a daisy-chain configuration using a single control signal cable. The last drive in the chain requires the terminator to be installed at PCB. The input lines have the following electrical specifications: Logic "0" = True = 0.0 VDC to 0.4 VDC at I in = 40MA (MAX) = LO Logic "1" = False = 2.5 VDC to 5.25 VDC at I in = 1 MA (OPEN) = HI The output lines are driven with a TTL open collector output stage capable of sinking a maximum of 40 MA at the logic "0" or TRUE state with a maximum voltage of 0.4 VDC measured at the driver. When the line driver is in the logic "1" or FALSE state driver transistor is off and the collector cutoff current is 250 microamperes. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM Q2000 PRODUCT DESCRIPTION OEM MANUAL 40-30011 REV.

Cylinder zero (0) will be free of defect areas. 2. No surface will have more than 12 defect areas. 3. No surface will have more than 4 tracks with mutiple defect areas. Quantum defines a defect area as an area equal to or less than 16 bits in length. Hence a defcet area 17 bits in length counts as 2 defect areas and a defect area of 16 bits in length counts as 1 defect area.
