DS1, DS2, DS3, DS4 cause the drive to be selected when the active drive select line matches the installed jumper. Jumper G, 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 Q500 is the last drive at the end of the control signal cable, a 220/330 ohm terminator pack must be installed at PCB location RN3. The terminator must be removed from RN3 is the drive is not at the end of a string of drives. The Quantum part number for the terminator pack is 13-12302. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM Q500 PRODUCT DESCRIPTION OEM MANUAL 81-50125 REV. E, DEC. 83 Notes on Installation ===================== Space Requirements ------------------ The Model Q500 is shipped with a face plate installed and shock mounts directly mounted to base casting. Mounting -------- The Model Q500 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 drive mounting bracket. Mounting screws lengths must be chosen so that no more than .130" of the screw is available to enter the mounting bracket 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 8 inch/pounds. Mounting holes: 6-32 UNC, 4 on the bottom and 2 on each side. DC Power Connector ------------------ DC power connector (P3) is a 4 pin AMP Mate-N-Lok connector P/N 350211-1 mounted on the solder side of the PCB. The recommended mating connector (J3) is AMP P/N 1-408424-0 utilizing AMP pins P/N 350078-4 (strip) or P/N 61173-4 (loose piece). J3 pins are labeled on J3 connector. +--------------+ |+-----J3-----+| pin 1 +12 Volts || 4 3 2 1 || pin 2 +12 Volts Return |+------------+| pin 3 + 5 Volts Return +--------------+ pin 4 + 5 Volts Interface Connectors -------------------- Two interface cable connections are required by the Model Q500, a control cable (J1) and a signal or data cable (J2). Connection to J1 is through a 34 pin pronted circuit board (PCB) edge connector. The pins are numbered 1 through 34 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 DC connector and is labeled. A key slot is provided between pins 4 and 6. The recommended mating connector for P1 is AMP ribbon connector P/N 88373-3. 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 AMP ribbon connector P/N 88373-6. A key slot is provided between pins 4 and 6. Ventilation ----------- The Model Q500 operates without a cooling fan provided the ambient air temperature does not exceed 122*F (50*C). Any user designed cabinet should provide adequate air circulation so that this maximum air temperature is not exceeded. Introduction ------------ The Model Q500 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 and WRITE GATE 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 location RN3. The maximum recommended cable length is 20 feet (6m). 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 = 250 uA (OPEN COLLECTOR) = 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 Q500 PRODUCT DESCRIPTION OEM MANUAL 81-50125 REV. E, DEC. 83 General Description =================== Quantum Model Q500 Disk Drive is a random access storage device using two, three, or four non-removable 5 " rigid disk platters as storage media. - Storage capacity of 20, 30, 40 megabytes - Winchester design reliability - Same physical size and mounting as ST412 drives - Airlock (TM) Proprietary Automatic Actuator Lock - Propritary, high resolution, quiet, rotary head position actuator - 5.00 Mbits/second transfer rate - Microprocessor controlled positioner, using an embedded wedge servo - Uses the same DC voltages and currents as ST412 drives Seek Time --------- +----------------------------------+--------+ | | Q500 | +----------------------------------+--------+ |Track-to-Track msec. typ. | 10 | +----------------------------------+--------+ |Average msec. typ. | 45 | | msec. max. | 49 | +----------------------------------+--------+ |Full Stroke msec. typ. | 80 | | msec. max. | 90 | +----------------------------------+--------+ |Latency msec. avg. | 8.5 | +----------------------------------+--------+ Media Quality Criteria ---------------------- Each drive that Quantum ships will meet or exceed the following standards of media quality: 1. Cylinder zero (0) will be free of defect areas. 2. No surface will have more than 10 defect areas. 3. No surface will have more than 4 tracks with mutiple defect areas. 4. No drive will have more than 1 error per megabyte of unformatted storage capacity. 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. Quantum uses a unique analog media test system which measures both the amplitude and phase disortion of each bit that can be recorded on all tracks of all surfaces. The test system provides a defect map which is shipped with each drive. The defect location is identified on the map by cylinder number, head number, number of bytes from index, and number of bits in length. The numbers are given in both decimal and hexadecimal notation for user convenience.
