2.0 Applicable standards and reference documentation

The drive has been developed as a system peripheral to the highest standards of design and construction. The drive depends upon its hos t equipment to provide adeq uate power and environment in order to a chieve optimum performance and compliance with applicable industry a nd governmental regulations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regulation. In par ticular, the drive must be securely m ount ed in o rder to guarante e th e spec ified pe rformanc e characteristics. Mounting by bottom holes must meet the requirements of Section 8.4.

2.1 Standards

Medalist Pro family drives comply with Seagate standa rds as noted in the appropriate s ections of this manual and the Seagate

SCSI Interface Product Manual

, part number 77738479 (Vol. 2).

Medalist Pro disc drives are UL recognized components per UL1950, CSA certified to CSA C22.2 No. 950M89, and VDE certified to VDE 0805 and EN 60950 .

2.1.1 Electromagnetic compatibility

The drive, as delivered, is designed f or s ystem integr ation and installation into a suitable enclosure prior to use. As such the drive is supplied as a subassembly and is not subjec t to Subpart B of Part 15 of the FCC Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communications.

The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides reasonable shielding. As such, the drive is capable of meeting the Class B limits of the FCC Rules and Regulations of the Canadian Department of Communications when properly packaged. However, it is the user’s responsibility to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be required if the enclosure do es not provide adeq uate shielding. If the I /O cables are extern al to the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host controller.

2.1.2 Electromagnetic susceptibility

As a component assem bly, the drive is not required to me et any suscep tibility perform ance requi rements. It is the responsibility of those integrating the dri ve within their systems to perform t hose t ests req uired a nd des i gn their system to ensure that equipm ent operating in the same system as the drive or external to the system does not adversely affect the performance of the drive. See Section 5.1.1 and Table 2a, DC power requirements.

2.2 Electromagnetic compliance

Seagate uses an independen t laboratory to confirm com pliance to the directives/standard(s) for CE Marking and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected system represents the most popular characteristics for test platforms. The system configurations include:

• 486, Pentium, and PowerPC microprocessors

• 3.5-inch floppy disc drive

• Keyboard

• Monitor/display

• Printer

• External modem

•Mouse Although the test system with this Seagate m odel com pli es to the direct ives/standard(s), we cannot guarantee

that all systems will comply. The computer manufacturer or system integrator shall confirm EMC compliance and provide CE Marking and C-Tick Marking for their product.

Electromagnetic compliance for the European Union

If this model has the CE Marking it complies with the European Union requirements of the Electromagnet ic Compatibility Directive 89/336/EEC of 03 M ay 198 9 as amended by Directive 92/31/EEC of 28 A pri l 19 92 and Directive 93/68/EEC of 22 July 1993.

3.0 General description

Medalist Pro drives combine magnetoresistive (MR) heads, partial respon se/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a SCSI-3 (F ast-20 and Fast-40) interf ace t o provide high performance, high capacity data storage for a variety of systems including high-end desktop systems, workstations, and entry level servers.

Fast-20 and F ast-40 (also known as Ultra SCSI and Ultra-2 SCSI) are negotiated transfer rates. These transfer rates will occur only if your host adapter also supports Fast-20 and Fast-40 data transfer rates. This drive also operates at SCSI-2/SCS I-3 data transfer rates for backward compatibility with non-Fast-20/Fast-40 capable SCSI host adapters.

Table 1 lists the features that differentiate the various Medalist Pro SCSI-3 Fast-20 and Fast-40 models.

Table 1: Drive model number vs. I/O features

Note.

[1] See Section 9.7.2, “Multimode—SE or LVD alternative.” The drive records and recovers data on 3.5-inch (86 mm) non-removeable discs.

The drive supports the Small Computer System Interface (SCSI) as described in the ANSI SCSI-2 and SCSI-3 interface specifications to the extent described in this manual (volume 1), which defines the product performance characteristics of the M edalist P ro family of drives, and the

SCSI Interface Product Manual

(volume 2), part number 77738479, which describes the general interface characteristics of this and other families of Seagate SCSI drives.

The drive’s interface supports multipl e initiators, disconnect/reconnect, and aut omatic features that relieve the host from the necessity of knowing the physical characteristics of the targets (logical block addressing is used).

The head and disc assembly (HDA) is sealed at the factory. Air circulates within the HDA through a nonreplaceable filter to maintain a contamination-free HDA environment.

Refer to Figure 2 for an exploded view of the drive. This exploded view is for information only—never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, med ia, actuator, etc.) as this requires special facilities. The drive contains no replaceable parts. Opening the HDA voids your warranty.

6 Medalist Pro Product Manual, Rev. D

Medalist Pro drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the landing zone when power is removed.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling. The shipping lock automati cally diseng ages when power is appli ed t o the drive and the head load process begins.

Medalist Pro drives deco de track 0 location dat a from t he ser vo data embedd ed on each surface to elim inate mechanical transducer adjustments and related relia bilit y con cer ns.

A high-performance actuator assembly with a low-inertia, balanced, pa tented, straight-arm design provides excellent performance with minimal power dissipation.

3.5 Unformatted a n d formatted capacities

Formatted capacity depends on the number of spare reallocation sectors reserved and the number of bytes per sector. The following table shows t he st andard OEM model read capacity data. Total LBAs = read capacity data shown below + 1.

3.6 Programmable drive capacity

Using the Mode Select command, the drive can change its capacity to something less than maximum. See Table 5.2.1-13 in the

SCSI Interface Product Manual

(part number 77738479). Refer to the Parameter list block descriptor, bytes 1, 2 and 3. A value of zero in bytes 1, 2 and 3 indicat es that the drive shall not change the capacity it is currently formatted to have. A n umber in bytes 1, 2 and 3 that is less than the maximum number of LBAs changes the total drive capacity to the value in the block descriptor bytes 1, 2 and 3. A value greater than the maximum number of LBAs is rounded down to the maximum capacity. Byte 0 is not used as the density code, but as the MSB of number of LBAs.

3.7 Factory installed accessories

The drive ships with a small bag of the two jumper plug types used for the J6, J2, and J1-Aux option select jumper headers.

3.8 Options (factory installed)

All customer reques ted options are inco rporated during prod uction or packaged at the manufactur ing facility before shipping. Some of the options available are:

• The capacities shown in Section 3.5. You can order other capacities by selecting a maximum LBA as shown

in Section 3.6 .

• Single unit shipping pack. The drive normally ships in bulk packaging to provide maximum protection against

transit damage. Units shipped in dividually require additional protection as provided by the singl e unit shipping pack. Specify this option if you are planning to ship single units to your customers.

• ESD and physical protection is accommodated by a protective plate called SeaShield which attaches to the

PCB.

Notes for Section 4.2.

[1] Execution time is measured from receip t of the last B yte of the Com mand Descri ptor Block (CDB) to the

request for a Status Byte Tr ansf er to the Initiator (excluding connect/disconnect).

[2] Maximum times are specified over the worst case conditions of temperature, voltage margins and dr ive

orientation. When comparing spec ified access times, care should be taken to distinguish between typical access times and maximum access times. The best comparison is obtained by system benchmark tests conducted under identical conditions. Maximum times do not include error recovery.

[3] Typical access times are measured und er nominal conditions of tempe rature, voltage, and horizontal ori-

entation as measured on a representative sample of drives. [4] Assumes no errors and no sector has been relocated. [5] Rate measured from the start of the first sector transfer to or from the host. [6] Assumes system ability to support the rates listed and no cable loss. [7] Simulated. [8] Access time = controller overhead + average seek time

Access to data = controller overhead + average seek time + latency time

4.3 S tar t/stop ti me

After DC power at nominal voltage has been applied, the drive becomes ready within 20 seconds if the Motor Start Opt ion is disabled (i.e. the m otor star ts as soon as the power has be en applied). If a recoverable error condition is detected during the star t sequence, the drive executes a recovery procedure which may cause the time to become ready to exceed 20 seconds. During spin up to read y time the drive responds to some commands over the SCSI interface in less than 3 seconds after application of power. Stop time is less than 20 seconds from removal of DC power.

If the Motor Start Opt ion is enabled, the internal cont roller accepts the comm ands listed in the SC SI Interface Product Manual less than 3 seconds after DC power has been applied. After the Motor Start Command has been received the drive becomes ready for normal operations within 13 seconds typical ly (excluding an error recovery procedure). The M otor Star t Command can also be used to command t he drive to stop the spindle (see

SCSI Interface Product Manual

, part number 77738479).

There is no power control switch on the drive.

4.4 Prefetch/multi-segmented cache control

The drive provides prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. “Cache” as used herein refers to the drive buffer storage space when it is used in “cache” operat ions. To select pre fetch and cache features the host sends the Mo de Select command with the proper values in the a pplicable bytes in Mode Page 08h (see

SCSI Interface Product Manual

, part number 7773 8479). Prefetch and cache operation are independent features from the standpoint that each is enabled and disabled independently via the Mode Select command. However, in actual operation the prefetch feature overlaps cache operation somewhat as is noted in Section 4.5.1 and 4.5.2.

All default cache and prefetch Mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Tables 9, 10, and 11.

4.5 Cache operation

In general, 380 Kbytes of the 512 Kbytes (860.5 Kbytes of 1,024 K bytes for “LC” and “LW” drives) of physical buffer space in the drive can be used as storage space for cache operations. The buffer contains memory from which data is read and to which data is written. The drive maintains a table of logical block disk medium addresses of the data stored in each segment of the buffer. If cache operation is enabled (RCD bit = 0 in Mode Page 08h, byte 2, bit 0. See

SCSI Interface Product Manual

(part numbe r 77738479), data req uested by the host with a Read command is retrieved from the buffer (if it is there), before any disc access is initiated. If cache operation is not enabled, the buffer (still segmented with required number of segm ents) is still used, but only as circular buffer segments during disc medium read ope rations (disregarding Prefetch operation for the moment). That is, the drive does not check in the buffer segments for the requested read data, but goes directly to the medium to retr ieve it. The retrieved data merely passes through some buffer segment on the way to the

12 Medalist Pro Product Manual, Rev. D

host. On a cache “miss”, all data transfers t o the host are in accordance with “buffer-full” rat io rules. On a cache “hit” the drive ignores the “buffer-full” ratio rules. See explanations associated with Mode page 02h (disconnect/ reconnect control) in the

SCSI Interface Product Manual

(part number 77738479). The following is a simplified description of a read operation with cache operation enabled: Case A - A Read command is received and the first logical block (LB) is already in cache:

1. Drive transfers to the initiator the first LB requested plus all subsequent contiguous LB’s that are already in

the cache. This data may be in multiple segments.

2. When the requested LB is reached that is not in any cache segment, the drive fetches it and any remaining

requested LBs from the disc and puts them in a segment of the cache. The drive transfers the remaining requested LBs from t he cac he to the hos t in accordance with the disconnec t/reconn ec t sp ecification m entioned above.

3. If the prefetch feature is enabled, refer to Section 4.5.2 for operation from this point. Case B - A Read command requests data, the first LB of which is not in any segment of the cache:

1. The drive fetches the requested LBs from the disc and transfers them into a segment, and th en the seg-

ment to the host.

2. If the prefetch feature is enabled, refer to Section 4.5.2 for operation from this point.

4.5.1 Caching write data

Write caching is a write operation by the drive that makes use of a drive buffer storage area where the dat a to be written to the medium is stored in one buffer segment.

Write caching is enabled independ ently from read caching. For write caching, the same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed independently, having nothing to do with wh ether or not read and write caching is enabled or disabled. When a write command is issued , the cache is first checked to see if a ny logical blocks that are to be written are al ready stored in the cache from a previous read or wr ite command. If there are, the respective cache segm ents are cleared. The new data is cached for subsequent Read commands.

If the number of write data logical blocks exceeds the size of the segment then being written into when the end of the segment is reached, the data is written into the beginning of the same cache segment, overwriting the data that was written there at the beginning of the operation. However, the drive does not overwrite data that has not yet been written to the medium.

Tables 9, 10, and 11 show Mode default settings for the drives.

4.5.2 Prefetch operation

If the Prefetch feature is enabled, data in contiguous logical blocks on the disc i mmedi ately beyond that which was requested by a Read command can be retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent Read comm and s that request those logical blocks (this is true even if “cache” operation is disabled). Though the prefetch operation uses the buffer as a “cache”, finding the requested data in the buffer is a prefe tch “hit”, not a “cache” operation “hit”. Prefetch is enabled using Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch. Since data that is prefetched replaces data already in some buffer segment(s), the host can limit the amount of prefetch data to optimize system performance. The max prefetch field (bytes 8 and 9) limits the am ount of prefetch. The drive does not use the prefetch “ceiling” field ( byt e s 10 an d 11).

Whenever prefet ch (read look-ahead) is enabled (enabled by DRA = 0), it operates under the control of ARLA (Adaptive Read Look-Ahead). If the host uses software interleave, A RLA enables prefetch of contiguous blocks from the disc when it senses t hat a prefetch “hit” w ill l ikely occu r, even if two consecutive read operations were not for phy sically contiguous bloc ks of data (e .g. “software interleav e”). ARLA disables prefetch when it decides that a prefetch “hit ” w ill not likely o ccur. If the h ost is not using software int er leave, and if two sequenti al re ad operations are not for contiguous blocks of data, ARLA disables prefetch, but as long as sequential read operations request contiguous blocks of data, ARLA keeps prefetch enabled.

5.0 Reliability specifications

The following reliability specifications assume correct host/drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints (see Section 8.4).

Note.

[1] Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.

5.1 Error rates

The error rates stated in this specification assume the following:

• The drive is operated per this specification using DC power as def ined in this manual (see Section 6.2).

• The drive has been formatted with the SCSI FORMAT commands.

• Errors caused by media defects or host system failures are excluded from error rate computations.

5.1.1 Environmental interference

When evaluating syste ms operation under conditions of Electromagnetic Interference (EMI), the performance of the drive within the system shall be considered acc eptable if the drive does not g enerate an unrecoverable condition.

An unrecoverable error, or unrecoverable condition, is defined as one that:

• Is not detected and corrected by the drive itself;

• Is not capable of being detected from the error or fault status provided through the driv e or SCSI interface; or

• Is not capable of being recovered by normal drive or system recovery procedures without operator intervention.

5.1.2 Read errors

Before determination or measurement of read error rates:

• The data that is to be used for measurement of read error rates must be v erifi ed as being written correctly on the m edia.

• All media defect induced errors must be excluded from error rate calculations.

5.1.3 Write errors

Write errors can occur a s a result of media defects, environmental interference, or equipment malfunction. Therefore, write errors are not predictable as a function of the number of bits passed.

If an unrecoverable write error occurs because of an equipment malfunction in the drive, the error is classified as a failure affecting MTBF. Unrecoverable write errors are those which cannot be corrected within two attempts at writing the record with a read verify after each attempt (exc luding media defects).

5.1.4 Seek errors

A seek error is defined as a failure of the drive to position the heads to the addres sed t rack. There shal l be no more than one recoverable seek errors in 10

physical seek operations. After detecting an initial seek error , the drive automatically reseeks to the addressed track up to 3 times. If a reseek is successful, the Extended Sense reports a seek positioning error (15h), no seek complete error (02h), or track follow error (09h), and the sense key reports a recovered error (1h). If all three reseeks fail, a seek positioning error (15h) is repor ted with a Medium error (3h) or Hardware error (4h) reported in the Sense Key. This is an unrecoverable seek error. Unrecoverable seek errors are classified as failures for MTBF calculations. Refer to Section 5.1.1.2 of the

SCSI

Interface Product Manual

(part numbe r 77738479) for Request Sense in formation. Appendix A of this ma nual

lists the sense keys and additional sense codes supported by the drives of this manual.

5.2 Reliability and service

You can enhance the reliability of Medalist Pro disc drives by ensuring that the drive receives adequate cooling. Section 6.4.1 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 8.3.1 provides recommended air-flow information.

5.2.1 Mean time between failure

The production disc drive shall achieve an MTBF of 800,000 hours when operated in an environment that ensures the case temperatures spe cified in Section 6.4.1 are not exceeded. Shor t-term excursions up to the specification limits of the operating environment will not affect MTBF performance.

The following expression defines MTBF

Estimated power-on operating hours in the period

MTBF per measurement period =

Number of drive failures in the period

Estimated power-on operation hours means power-up hours per disc drive times the total number of disc drives in service. Each disc drive shall have accumulated at least nine months of operation. Data shall be calculated on a rolling average base for a minimum perio d of six months.

Drive failure means any stoppage or substandard performance caused by drive malfunction.

5.2.2 Preventive maintenance

No routine scheduled preventiv e maintenance shall be required.

5.2.3 Service life

The drive shall have a usef ul service life of five years. Depot repair or replacement of major parts is permitted during the lifetime (see Section 5.2.4).

5.2.4 Service ph ilosophy

Special equipment is required to repair the drive HDA. In order to achieve the above service life, repairs must be performed only at a properly equipped and st affed service and repai r facility. Troubleshooting and repair of PCBs in the field is not rec ommended, because of the extensive diagnost ic equipment required for effective servicing. Also, there are no spare parts available for this drive. Drive warranty is voided if the HDA is opened.

5.2.5 Service tools

No special tools are required for site installation or recommended for site maintenance. Refer to Section 5.2.4. The depot repair philosophy of the drive precludes the necessity for special tools. Field repair of the drive is not practical since there are no user purchasable parts in the drive.

Medalis t Pr o P roduct Manual, Rev. D 15

5.2.6 Hot plugging Medalist Pro disc drives

The ANSI SPI-2 (T10/1142D) docum ent defines the physical requirements for removal and insertion of SCSI devices on the SCSI bus. Four cases are addressed. The cases are differentiated by the state of the SCSI bus when the removal or insertion occurs.

Seagate Medalist Pro disc drives support four hot plugging cases. Provision shall be made by the system such that a device being inserted makes power and ground connections prior to the connection of any device signal contact to the bus. A device being removed shall maintain power and ground connections af ter the disc onnection of any device signal contact from the bus (see SFF-8046, SCA-2 specification).

It is the responsibility of the systems integrator to assure that no hazards from temperature, energy, voltage, or ESD potential are presented during the hot connect/disconnect operation .

All I/O processes for the SCSI device being inser ted or removed shall be quiesce nt. All SCSI devices on the bus shall have receivers that conform to the SPI-2 standard.

If the device being hot plugged uses single-ended (SE) drivers and the bus is currently operating in low voltage differential (LVD) mod e, then all I/O proce sses for al l devices on the bus must be completed, and the bus q uiesced, before attempting to hot plug. Following the insertion of the newly installed device, the SCSI host adapter must issue a B us Rese t, followed by a synchronous transfer negotiation. Failure to perform the SCSI Bus Reset could result in erroneous bus operations.

The SCSI bus termination and termination power source shall be external to the device being inserted or removed.

End users should not mix devices with high voltage differential (HVD) drivers and receivers and devices with SE, LVD, or multimode drivers and receivers on the same SCSI bus since the common mode voltages in the HVD environment may not be controlled to safe levels for SE and LVD devices (see ANSI SPI-2).

The disc drive spindle must come to a complete stop pri or to completely removing the drive from the cabinet chassis. Use of the Stop Spindle command or partial withdrawal of the drive, enough to be disconnected from the power source, prior to removal are methods for insuring that this requirement is met. During drive insertion, care should be taken to avoid exceeding the limits stated in Section 6.4.4, "Sh ock and vibration," o f this manual.

5.2.7 S.M .A . R . T.

S.M.A.R.T. is an acronym for Self-Monitoring Ana lysis and Re porting Techn ology. This technology is intended to recognize conditions that indicate imminen t drive failure and is designed t o provide sufficient war ning of a failure to allow you to back up the data before an actual failure occurs.

Note. The drive’s firmware will monitor specific attributes for degradation over time but can’t predict instanta-

neous drive failures.

Each monitored attribute has been selected to monitor a spe cific set of failure conditions in the operating performance of the drive and the thresholds are optimized to minimize “false” and “failed” predictions.

Controling S .M .A.R.T.

The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Inf o rmational Exceptions Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read an d write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line functions.

You can measure off-line attributes and force the drive to save the data by using the Rezero command. Forcing S.M.A.R.T resets the timer so that the next scheduled interrupt is in two hours.

Case 1 A ll bus devices powered off during removal or insertion Case 2 RST signal asser ted continuousl y during rem oval or insertion Case 3 Current I/O processes not allowed during insertion or removal Case 4 Current I/O process allowed during insertio n or removal, except on the device being changed

16 Medalist Pro Product Manual, Rev. D

You can interrogate the drive through the host to determine the time remaining before the next scheduled measurement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows you to control when S.M.A.R.T. interruptions occ ur. Forcing S.M.A.R.T. with the RTZ command resets the timer.

Performance impact

S.M.A.R.T. attribute data is saved to the disc so that the even ts that caused a predictive failure can be recreated. The drive measures and saves parameters once every two hours subject to an idle period on the interface. The process of measuring off-line attribute data and saving data to the disc is uninterruptable. The maximum on-line only (DESCPT = 0; PERF = 1) processing delay is 60 ms. The maximum fully-enabled (DEXCPT = 0, PERF = 0) processing delay is 450 ms.

Repor tin g c o ntrol

Reporting is controlled in the Informational Exceptions Control mode page (1Ch). Subject to the repor ting method, the firmware w ill issue to the host an 01-5D XX sen se code. The error code is prese rved through bus resets and power cycles.

Determining rate

S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to an unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given a ttribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of operations is referred to as the Interval Counter.

S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for t he curren t interval. This counter is referred to as the Failure Counter.

Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set thresholds for the number of errors and their interval. If the number of errors ex ceeds the threshold before the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to be acceptable. In either case, the interval and failure counters are reset and the process starts over.

Predictive failures

S.M.A.R.T. signals predictive failures when the drive is p erforming unac cept ably for a period of tim e. The firmware keeps a running count of the number of times the error rat e for each attribute is unacceptable. To accomplish this, a counter is in cremented eac h time the error rate is una cceptable and decrem ented (not to exceed zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.

5.2.8 Product warranty

Beginning on the da te of shipment to custo mer and continuing for a period of three years, Seagate warrants that each product (including components and subassemblies) or spare part that fails to function properly under normal use due to defect in m aterials on wor kman ship or due to n onconformance to the appl icable specifications will be repaired or replaced, at Seagate’s option and at no charge to customer, if returned by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s Warranty Procedure. Seagate will pay for transpor ting the repair or replacement item to customer. For more detailed warranty information refer to the Standard terms and conditions of Purchase for Seagate products.

Shipping

When transpor ting or shipping a drive, a Seagate approved container must be us ed. Keep your original box. They are easily identified by the Seagate App roved Packag e label. Shipping a drive in a non-approved container voids the drive warranty .

Seagate repair centers may refuse recei pt of components improper ly packaged or obvious ly dam aged in transit. Contact your Authorized Seagate Distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in handling computer equipment.

Medalis t Pr o P roduct Manual, Rev. D 17

pleted and that the drive is able to accept selection by the host initiator. [3] See +12 V current profile in Figure 3a. [4] This condition occurs when the Motor Star t Option is enabled and the drive has not yet received a Start

Motor co mmand. [5] See Section 6.2.1 “Conducted Noise I mmunity.” Specified voltage tol erance is inclusive of ripple, noise,

and transient response. [6] Operating condition is defined as random seek read operations with a block count of 64.

General Notes from Table 2a:

1. Minimum current loading for each supply voltage is not less than 4% of the maximum operating current

shown.

2. The +5 and +12 volt supplies shall employ separate ground returns.

3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive

power requirements should be noted. Where multiple units are powered on simultaneously, the peak star t ing current must be available to each device.

6.2.1 Conducted noise immunity

Noise is specified as a per iodic and random distri bution of frequencies covering a band from DC t o 10 mHz. Maximum allowed noise values given below are peak to peak measurements and apply at the drive power connector.

6.2.2 Power sequencing

The drive does not req uire power sequencing. T he dr ive protects against ina dvertent wr iting duri ng power-up and down. Daisy-chain operation requ ires that power be mainta ined on the ter minat ed drive to ensure p roper termination of the peripheral I/O c ables. To automatically delay motor start based on t he target ID (SCSI ID) enable the Delay Motor Start option and disable the Enable Motor Star t option on the J2 conne ctor. See Section 8.1 for pin selection info rmation. To delay the motor until the drive receives a Start Unit command, enable the Enable Motor Start option on the J2 connector.

6.3 Power dissipation

For drives with single-ended interface circuits, typical operating random read/write power dissipation is 14.1 watts (48.1 BTUs per hour) of DC power average at nominal voltages. Typical power dissipation under idle conditions is 12.3 watts (42.0 BTUs per hour). Standby power is 4.1 wa tts (14.0 BTUs per hour).

For drives with low voltage differential interface circuits (LVD), typical operating random read/write power dissipation is 14.6 watts (49.8 B TUs pe r hour) of DC power average at nominal voltages. Typical power dissipation under idle conditions is 13.5 watts (46.0 BTUs per hour). Standby power is 4.5 watts (15.3 BTUs per hour).

6.4 Environment al limits

Temperature and h umidity values experienced by the drive must b e suc h that con dens ation does not occur on any drive part. Altitude and atmospheric pres sure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum Wet Bulb temperature is 82°F (28°C).

6.4.1 Temper ature

a. Operating

The drive meets all specifications over a 41°F to 131°F (5°C to 55°C) drive ambient temperature range with a maximum temperature gradient of 36°F (20°C) per hour. The enclosure for the drive should be designed such that the temperatures at the locations specified in Table 3, column 1 are not exceeded. Air flow ma y be needed to achieve these temperature values. Operation at case tem peratures [3] ab ove these values may adversely affect the drives ability to meet specifications.

The MTBF specification for the drive is based on operating in an environment that ensures th at the case temperatures specified in Table 3, column 2 are not exceeded. Occasional excursions to drive ambient temperatures of 131°F (55°C) or 41°F (5°C) may occur without impact to specified MTBF. Air flow may be needed to achieve these temperatures. Continual or sustained operation at case temperatures above these values may degrade MTBF.

To confirm that the required coolin g for the Medalist Pro electronics and HDA is provided, place the drive in its final mechanical configuration, perform random write/read operations. After the temperatures stabilize, measure the case temperature of the components listed in Ta ble 3.

Operation of the drive at the maximum case temperature is intended for short time periods only. Continuous operation at the elevated temperatures will reduce product reliability.

T able 3: PCB and HDA temperatures

Note.

[1] The temperatures in Column 1 are calculated and may not reflect actual operating values. Sufficient

cooling air may be required to ensure that t hese values are not exceeded. Large thermal gradients

should be avoided. [2] No point anywhere on the HDA surface should exceed this value. [3] PCB mounted integrated circuit case.

6.4.4 Shock and vibration

Shock and vibration limits speci fied in this doc um ent are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criter ia is applied, resonances may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods shown in Figure 5 , and in accordanc e with the restrictions of Section 8.4. Orientation of the side nearest the LED may be up or down.

6.4.4.1 Shock

a. Operating—normal

The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 10 g at a maximum duration of 11 ms (half sinewave). Shock may be applied in the X, Y, or Z axis.

b. Non-operating

The limits of non-operating shock shall apply to all conditions of handling and transportation . This includes both isolated drives and integrated drives.

The drive subjected to nonrepetitive shock not exceeding 75 g at a maximum duration of 11 ms (half sinewave) shall not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.

Maximum 2 msec rotary shock (half sinewav e) 12,000 radians/sec

The drive subjected to non repetitive shock not exceeding 200 g at a du ration of 2 msec (half sinewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis.

7.0 Defect and error management

The drive, as delivered, complies with this specification. The read error rate and specified storage capacity are not dependent upon use of defect management routines by the host (initiator).

Defect and error management in the SCSI system involves t he drive internal defect/error management and SCSI systems error considerations (errors in communications between Initiator and the dri ve). Tools for use in designing a defect/error management plan are briefly o utlined in this section, with references to other sections where further details are given.

7.1 Drive internal defects and errors

Identified defects are recorded on the drive defects list tracks (referred to as the primary o r ETF defect list). These known defects are reallocated during the initial drive format operation at the factory. (See Section

5.2.1.2, “Format Unit command” in the

SCSI Interface Product Manual

, part number 77738479). Data correc-

tion by ECC will be applied to recover data from additional flaws if they occur. Details of the SCSI commands support ed by the drive are described in

SCSI Interface Product Manual

7.2 SCSI system s errors

Information on the reporting of operational errors or faults across the interface is given in the SCSI I nterface Product Manual. Message Protocol System is described in the

SCSI Interface Product Manual

. Severa l of the messages are used in the SCSI systems error manage ment system. The Request Sense command retur ns information to the host about numerous kinds of errors or faults. Appendix A of this manual lists the sense keys and additional sense codes supp orted by the drives of this manual. The Receive Diagnostic Results re ports the results of diagnostic operations performed by the drive.

Status returned by the drive to the Initiator is described in the

SCSI Interface Product Manual

. Status reporting plays a role in the SCSI systems error management and its use in that respect is described in sections where the various commands are discussed.

Medalis t Pr o P roduct Manual, Rev. D 33

8.0 Installation

The first thing to do wh en installing a dr ive is to set the drive ID (sele ct) on the SCSI bus and set up cer tain operating options. This is usually done by installing small shorting jumpers on the pins of connector J2 on the PCB (or J1-Auxiliary on the “W” and “LW” models), or via the drive to host I/O signals on “WC” and “LC” models. Some users connect cables to J6 or J1-Auxiliary and perform the set-up using remote switches.

If your sys tem is “SCAM” (SCSI Confi gured A ut o Magically ) complia nt, the syst em assign s the driv e ID ov er the interface, so there is no need to be concerned ab out drive ID. Setting the drive ID jumpers doe sn’t hur t anything, but is not necessary.

If your syste m is not “SCAM” compli an t you need to set the drive ID using the ID jumpers.

Configure drive options

For option jumper locations and definitions refer to Figures 9, 10, 11, 12, 13, and 14. Drive default mode parameters are not normally needed for installation. Refer to Section 9.3.2 for default mode parameters if they are needed.

• Ensure that the SCSI ID of the drive is not the same as the host adapter. Most host adapters use SCSI ID 7.

ID 7 is the highest priority on both 8 and 16 bit data buses.

• If multiple devices are on the bus set the drive SCSI ID to one that is not presently used by other devices on

the bus.

• If the drive is the only device on the bus, attach it to the end of the SCSI bus cable. Permanently installed ter-

minators must be enabled on the drive for “N” and “W” models using jumper plug TE if termination is not provided by the host equipment. On “WC,” “LC,” and “L W” m odel s, external terminators must be provided by the user, systems integrator or host equipment manufacturer.

• If the drive is attached to a bus that contains ot her devices, and the new drive is not attached to the end of

the bus, the Terminator Enable jumper (TE) should be removed from the new drive.

Note. For additional information about terminat or requirem ents, refer to Sections 9.8 and 9.9.

• Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after

power has been applied, recycle the drive power to make the new settings effective.

• Installation instructions are provided by host system document ation or with any additiona lly purchased drive

installation software. If necessary see Section 10 for Seagate support ser vic es telephone numbers.

• Do not remove the manufacturer’s installed lab els from the drive and do not cover with additional labels, as

the manufacturer labels contain information required when ser vicing the product.

Formatting

• It is not necessary to low level format this drive. The drive is shipped from the factory low level formatted in

512 byte sectors.

• High level format the dr ive involves assigning one or mo re partitions or logical dr ives to the drive volume.

Follow the instructions in the system manuals for the system into which the drive is to be installed.

• Systems that have Windows 95 Operating System version 950B (thi s has FAT 32) or later do not need to

partition the drive.

8.1 Dri ve ID/optio n select heade r

Figures 9 through 11 show views of th e drive ID select ju mper connect ors. Figure 12 shows the op tion select jumper connector for all models. Figure 10 shows a rear view of model drives fo r the purpose of showing J1auxiliary of the drive. Both J1-auxil iary and J6 have pins for selecting drive ID and for connecting the remote LED cable. Only one or the other should be used, although using both at the same time would not damage the drive. The notes following the figures desc ri be t he fun ctions of the var ious jumper positions on th e connectors J2, J1-Auxiliary and J6. S ee your local drive sales representative for suggested par t num ber. A bag containing jumper plugs is shipped with standard OEM drives.

J2 Jumper Installation Jumper Function Description

TE (Applies only to “N” and “W” models)

With the jumper installed, the On-board (non-removable) terminator circuits are enabled (connected to the I/O lines). Default is jumper installed.

Off Ter minato r circuits not enabled (not connected to I/O lines).

SE (Applies only to “LW” and “LC” models)

On Forces drive to use single-ended I/O drivers/receivers only. Off Drive can operate on the i nterface in low voltage differential mode or single-end ed, depend -

ing on the voltage state of the I/O “DIFFSENS” line. Default is no jumper on.

DS ME (A p plies t o a l l mode ls )

Off

Off Spindle starts immediately after power up - Default setting. Off On Drive spindle does not start until Start Unit command received from host. On Off Spindle Star tup is delayed by SCSI ID times 12 seconds after power is applied, i.e., drive 0

spindle starts im mediately when DC power connected, dr ive 1 starts after 12 secon d delay, drive 2 starts after 24 second delay, etc.

On On Drive spindle star ts when Sta rt Unit com mand received from host. Delayed star t feature is

overridden and does not apply when ME jumper is installed.

PD (Appli e s to all models )

On Parity checking and parity error reporting by the drive is disabled. Off

Drive checks for parity and reports result of parity checking to host. Default is PD jumper not installed.

RES (Applies to all models)

Off Reserved jumper position. Default is no jumper installed.

TP2 TP1 (Does not apply to “WC” models)

Off Off No terminator power is connected to drive terminators or SCSI bus I/O cable*. On

Off Drive supplies its own terminator power only. Jumper on this position is factory default. Off On Drive supplies power to SCSI bus I/O cable*; none to internal ter m inat ors. When drives have

differential I/O circuits, a jumper on the TP1 position may be needed to power external terminators (see system documentation).

On On Drive supplies terminator power to itself (internal connection) and to SCSI bus I/O cable*.

This is a legal jumper setting.

TP1 and TP2 “Positio n A” (Applies only to “N” and “W”)

On This horizontally p ositioned jumper across the t wo TP positions furthest from the PCB edge,

connects terminator power from SCS I bus I/O Termpower cable* to the drive’s internal terminators (for single-ended I/O only).

Off See above explanations for TP jumpers.

TP (Applies only to “LW” model)

Off No terminator power is connected to SCSI bus I/O cable.* Default is no jumpers on. On Drive supplies power to SCSI bus I/O cable.* A jumper on the TP1 position may be needed to

power external terminators (see Section 9.8 and Figure 10).

Medalis t Pr o P roduct Manual, Rev. D 41

8.2 Dri ve orientati on

The balanced rotary arm actuator design of the drive allows it to be mounted in any orientation. All drive performance characterization, however, has been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, and these are the two preferred mounting orientations.

8.3 Cooling

Cabinet cooling must be designed by the customer so that the ambient temp erature immedi ately surrounding the drive will not exceed temper ature conditions specified in Section 6 .4.1, “Te mperature.” Specif ic consideration should be given to make sure adequate air circulation is present around the printed circuit board (PCB) to meet the requirements of Section 6.4.1, “Temperature.”

8.3.1 Air flow

The rack, cabinet, or drawer environment for the Medalist P ro drive must provide heat removal from t he electronics and head and disc assem bly (HDA). You should confir m that adequate heat removal is provided using the temperature measurement guidelines descr ibed in Section 6.4.1.

Forced air flow may be required to keep temperatures at or below the specified case temperatures of Table 3, Column 2, in which case the drive should be or iented, or air flow directed, s o that the least amount of air flow resistance is created while providing air flow to the electronics and HDA. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources within the rack, cabinet, or drawer environment.

If forced air is determined to be neces sary, possible air-flow patterns are shown in Figure 15. T he ai r-flow patterns are created by one or more fans, either forcing or drawi ng air as shown in the illustrations. Conduction, convection, or other forc ed air-flow patterns are acceptable as long as the temperature measurement guidelines of Section 6.4.1 are met.

8.4 Dri ve mountin g

Refer to Figure 5 on page 25 for an illustration of the recommended mounting orientations When mounting the dri ve using the bot tom holes (x-y plane in Figure 5) care m ust b e t aken to e ns ure that the

drive is not physically distorted due to a stiff non-flat mounting surface. The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable mounting surface stiffness:

where ‘k’ represents the mounting surface stiffness (units of lb/in or N/mm), and ‘x’ represents the out-of-plane mounting surface distor tion (units of inches or millimeters). T he out-of-plane distor tion (‘x’) is determined by defining a plane with t hree of the four mount ing points fixed and evaluating the out-of-plan e deflection of the fourth mounting point when a known force is applied to the fourth point.

Note. Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Tech-

nology that the drive can mee t the shock and vibration specifications given herein while mounted in such an adapter frame. Adapter frames that are available may not have a mechanical structure capable of mounting the drive so that it can meet the shock and vibration specifications listed in this manual.

8.5 Grounding

Signal ground (PCB) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which the drive is mounted is connected directly to the HDA and PCB with no electrically isolating shock mounts. If it i s desired for the system chassis to not be connected to the HDA/PCB ground, the systems integrator or user must p rovide a nonconductive (electrically isolating) method of moun ting the drive in the host equipment.

Increased radiated emissions m ay result if you do not provide the maxi mum surface area ground connection between system ground and drive ground. This is the system designer’s and integrator’s responsibilit y.

9.3.2 Mode Sense data

The Mode Sense com mand provides a me ans for the drive to repor t its operating parameters to t he initiator. The drive maintains four sets of Mode parameters, Default values, Saved values, Current values and Changeable values.

Default values are hard coded in the drive firm ware that is stored i n flash EPROM no nvolatile memory o n the drive PCB. Default values can be changed only by downloading a complete set of new firmware into the flash EPROM. An initiator can request and receive from the dr ive a list of Default values and use those in a Mode Select command to set up new Current and Saved values, where the val ues are changeable.

Saved values are stored on the disk media using a Mode Select command. Only parameter values that are allowed to be changed can be changed by this method. See “Changeable values” defined below . Par ameters in the Saved values list that are not changeable by the Mode Select command get their values from the Default values storage.

Current values are volatil e values currently being used by the drive to control its operation. A Mode Select command can be used to c han ge t hese values (only t hose t hat are c han geable). Or i ginally, they are installed from Saved or Default values after a power on reset, hard reset, or Bus Device Reset message.

Changeable values form a bit m ask, stored in nonvolatile memor y, that dictates which of the Current values and Saved values can be changed by a Mode Select command. A “one” allows a change to a corresponding bit; a “zero” allows no change. For example, in Table 9 refer to Mode page 01, in the row entitled “CHG”. These are hex numbers representing the changeable values for Mode page 01. Note that bytes 04, 05, 06, and 07 are not changeable, because those fields are all zeros. If some changeable code had a hex value EF , that equates to the binary pattern 1110 1111 . If there is a zero in any bit position in the field, it means that bit is not changeable. Bits 7, 6, 5, 3, 2, 1, and 0 are changeable, because those bits are all ones. Bit 4 is not changeable.

Though the drive always reports non-zero values in bytes 00 and 01, those pa rticular bytes are never changeable.

The Changeable values list can only be changed by downloading new firmware into the flash EPROM. On standard OEM drives the Saved values are taken from the Default values list and stored into the Saved val-

ues storage location on the media prior to shipping. When a drive is powered up, it takes Saved values from the media and stores them t o the C urrent values stor-

age in volatile memory. It is not possible to change the Current values (or the sav ed values) with a Mode Select command before the drive is up to speed and is “ready.” An attempt to do so results in a “Check Condition” status being returned.

Note. Becaus e the re may be several different versions of drive control firmware in the total population of

drives in the field, the Mode Sense values given in the following tables may not exactly match those of some drives.

50 Medalist Pro Product Manual, Rev. D

The following tables list the values of the data bytes returned by the drive in response to the Mode Sense command pages. See the

SCSI Interface Product Manual

Definitions: SAV = Saved value

DEF = Default value. Standard drives are shipped configured this way. CHG = Changeable bits; indicates if current and saved values are changeable.

[1] Though byte 12, bit 7 (A0) is shown as changeable, the FSW func tion governed by that bit is not imple-

mented by this drive.

[2] “L W” and “LC” setting is “03.”

9.6.2 SCSI interface physical description

The drive models described by this product manual suppor t the physical interface requirements of the SCSI-3 Parallel Interfa ce -2 (SPI-2) s tandards as define d in American National Standard d ocume nt X3T 10/1142D, and operate compatibly at the interface with devices that only support earlier SCSI-2 and SCSI-3 standards. It should be noted that this is only tr ue if the systems engineering has been correc tly done, and if earlier SCS I-2 and SCSI-3 devices respond in an acceptable manner (per applicable SCSI Standards) to reject newer SCSI-3 protocol extensions that they don’t support.

The family of drives in this manual supports the single-ended and low voltage differential physical interconnects (hereafter referred to as SE and LVD, respectively) as described in the ANSI SPI-2 standard. Drive models whose model numbers end with “N,” “W,” and “WC” implement SE drivers and receivers. Drive models whose model numbers end with “LC” and “LW” implement driver and receiver circuits that can operate either SE or LVD (but never HVD).

The drives typically operate on a daisy-chain interface in which other SCSI devices are also operating. Devices on the daisy chain must all operate in the same mode, either SE or LVD, but not a mixture of these. On the interface daisy chain, all signals are common between all devices on the chain, or bus, as it is also called. This daisy chain of SCSI devices must be term inated at both ends wi th the proper impedance in order to operate correctly. In termediate SCSI devices sh all not be terminated. In some cases, the SC SI devices at each end have onboard termination circuits that can be enabled by installation of a jumper plug (TE) on the device. These termination circuits receive power from either a sou rce internal to the device, or from a l ine in the interface cable specificall y powered for that purpose. On SE drive models “N” and “ W,” terminator power source can be selected using the TP jumpers on the option select header J2. TE is also on the option select header J2 for models “N” and “W. ” See Section 8.1 f or details. Models “WC,” “LC,” and “L W” have no onboard termination circuits. Some type of external termination circuits must be provided for these drives by the end user or designers of the equipment into which the drives will be integrated. See Standa rd X3T10/ 1142D, sections 6.4 and 6.5 for the maximum number of devices that can successf ully operate at various interface transfer rates on SE and LVD daisy chains.

“LC” and “WC” model drives plug into PCB or bulkhead connectors in the Host. They may be connected in a daisy-chain by the host backplane wiring or PCB c ircuit runs that have adequate DC current carrying capacity to support the numbe r of drives plugged into the PCB or bulkhead connect ors. A single 80 pin I/O connector cable cannot suppor t the DC c urrent needs of several drives, so no daisy chai n cables beyond the bulkhead connectors should be used. A single dri ve connected via a cable to a h ost 80 pin I/ O connector is no t recommended.

Table 14 shows the interface transfer rates supported by the various drive models defined in this manual.

Table 14: Interface transfer rates supported

9.6.3 SCSI interface cable requirements

The characteristics of cables used to connect SCSI-3 parallel interface devices are discussed in detail in section 6 of ANSI Standard X3T10 /1142D. The cable characteristics that must be considered when in terconnecting the drives described in this manual in a SCSI-3 parallel, daisy-chain interconnected system are:

• characteristic impedance (see section 6.1)

• propagation delay (see section 6.1)

• cumulative length (see sections 6.4 and 6.5)

• stub length (see sections 6.4 and 6.5)

• device spacing (see sections 6.4 and 6.5)

Medalis t Pr o P roduct Manual, Rev. D 59

To minimize discontinuances and signal reflections, cables of different impedances should not be used in the same bus. Implementations may require trade-offs in shielding effectiveness, cable length, number of loads and spacing, transfer rates, and cost to achieve satisfactory system operation. If shielded and unshielded cables are mixed within the same SCS I bus, the effect of impedan ce mismatc h must be c arefully cons idered. Proper impedance matching is especially important in order to maintain adequate margin at FAST-20 and FA ST-40 S CSI transfer rates.

For “WC” an d “L C ” mo de l s:

The 80 pin connector option is intended for use on drives that plug directly into a PCB or wall/bracket mounted connector in the host equipment. In such installations, all backplane wiring segments are subject to the electromagnetic concepts presented in St andard X3T10/1142D, section 6. For “WC” and “LC” model dri ves, installations with connectors on cables are not recommended.

9.6.3.1 Single-ended I/O circuits (“N” and “W” models)

The maximum total cable length allowed with drives having single-ended I/O driver and receiver circuits depends on several factors. Table 15 lists the maximum leng ths allowed for different configurations of drive usage. These values are from the ANSI SCSI -3 Fast-20 (also called Ultra SCSI) s pecification X3T10/1071D. All device I/O lines must have equal to or less than 25 pf capacitance to ground, m easured at the beginn ing of the stub.

A stub length of no more than 0.1 meter (0.33 foot) is allowed off the main line interconnection with any connected equipment. The stub length is measured from the transceiver to the connection to the mainline SCSI bus.

Single-ended I/O pin assignments are shown in Tables 16, 17, and 19.

9.6.4 Mating connecto rs

Part numbers for the different t ype connectors that mate with the various Medalist Pro I/O connectors are given in the following sections.

9.6.4.1 Mating connectors for “N” models

The nonshielded cable connector shall be a 50 c onductor connect or consisting of two rows of 25 female contacts with adjacent contacts 0.1 inches (2.54 mm) apart.

9.6.4.2 Mating connectors for “W” and “LW” models

The nonshielded cable connector shall be a 68 conductor connector consisting of two rows of 34 male contacts with adjacent contacts 0.050 inches (1.27 mm) apart.

Recommended mating flat cable connector part numbers are:

[1] See Figure 19. The drive device connector is a nonshielded 68 conductor conne ctor consisting of two rows of 34 female pins

with adjacent pins 0.050 inches (1.27 mm) apar t. The c onnector is keyed by means of its shape (see Figure

21).

9.6.4.3 Mating connectors for “WC” and “LC” models

The nonshielded connector shall be an 80 conductor connector consisting of two rows of 40 contacts with adjacent contacts 0.050 inches (1.27 mm) apart. I/O connection using a cable is not recommended. The length and size of the host equipment DC power carrying conductors from the DC power source to the host equipment 80 pin disk drive interface connector(s) should be strictly designed according to proper power transmission design concepts. No possibility for the equipment user to att ach an 80 pin cable/connector sh ould be allowed, since the length of the DC power carrying conductors could not be controlled and therefore could become too long for safe power transmission to the drive. Daisy-chain 80 conductor cables should especially not be allowed, since the power-carrying co nductors on the 80 conduc tor interface were not intended to suppor t a series of drives.

9.7 Electrical descr iption

“N” and “W” models use single-ended interface signals. These signals must be terminated with 110-ohm active termination circuits at each end o f the total cable. Single-ended circuits use open col lector or three state drivers. These models can be configured to provide the SCSI termination.

“WC” and “LC” models use the single connection attachment (SCA) connector. This 80-pin connector is designed to plug directly into a back panel or plane. No external cables are required. Active terminators on the back panel must be provided by the user. This connector is not recommended where cabling is required.

“LC” and “L W” models are Multimode drives. That is, t heir I/O circuits can operate as either single-ended or low voltage differential drivers/receivers (selectable using the I/O “DIFFSENS” line). They require exter nal ter minators. See Section 9.7.2 for additional information on these models.

Note. The S CS I protocol c hip drives the upper eight data and parity bits of the SCSI bus even when operat-

ing in narrow (eight bit) mode. This is normal operation for this chip. If the unused data bit signals are connected to conductors that extend out beyond this drive’s SCSI connector, correct termination must be provided for these unused signals at the device/system at each end of the bus onto which this drive is connected. T ermination is required to control radiated emissions and conducted noise on other SCSI bus signals.

See ANSI Standard X3T10/1142D for detailed electrical specifications.

9.7.1 Single-ended drivers/recei vers

For “N,” “W,” and “WC” models which use single-ended drivers and receivers, typical circuits are shown in Figure 23. Terminator circuits (Note [1]) are to be enabled only when the disc drive is first or last in the daisy chain.

Transmitter characteristics

Single-ended drives use an ANSI SCSI compatible open collector single-ended driver. This driver is capable of sinking a current of 48 mA with a low level output voltage of 0.4 volt.

Medalis t Pr o P roduct Manual, Rev. D 71

Receiver characteristics

Single-ended drives use an ANSI SCSI single-ended receiver with hysteresis gate or equivalent as a line receiver.

Figure 23. Single-ended transmitters and receivers

The difference in the voltages between input and output signals is due to the losses in the cable.

plug TP. See Figure 12. Applies to “N” and “W” models.

9.7.2 Multimode—SE or LVD alternative

“LW” and “LC” models have I/O circuits that can operate either in single-ended (SE) or low voltage differential mode (LVD). Wh en the interface “DIFFSNS” line is between 0 V and .6 V, the drive interface circuits operate single-ended and up to and including 20 M transfers/s (Fast-20 or Ultra-1 SCSI). When “DIFFSENS” is betwen +0.7 V and +1.9 V, the drive interface circuits operate low voltage differential and up to and including 40 M transfers/s or less (Fast-40 or Ultra-2 SCSI). This arrangement is not intended to allow dynamically changi ng transmission modes, but rather to preven t incompatible devices from attempting to interoperate. Drives must operate only in the mode for which the install ation and interface cabling is designed. Multimode I/O circuits used by “LC” and “LW” devices do not operate at high voltage differential levels and should never be exposed to high voltage differential environments unless the common m ode voltages in the environment are cont rolled to safe levels for single-ended and low voltage differential devices (see the ANSI SPI-2 specification X3T10/ 1142D).

Multimode signals

Multimode circuit SE alternat ive signal characteristics are the same as descr ibed in Section 9.7.1. The SE alternative for these circuits is selected as described above. SE cables and termination must be used.

Multimode circuit LVD alternative signal characteristics are not the same as the differential signals described in Section 9.7.2.1. The Multimode signal lines (either SE or LVD) should be terminated with 110 ohm active terminator circuits at each end of the total cable. Termination of the I/O lines must be provided for by the Host equipment designers or end users.

The SE and differential alternatives are mutually exclusive.

9.8 Terminator requirements

Internal disc drive I/O term ination (provided only in model “N” and “W” drives single ended I/O mo del drives) consists of active circuits in an LSI modul e that is per manently m ounted on the PCB. All single initiato r/single target (non-daisy-chain) appl ications require t hat the Initiator and disc dr ive be ter minated. Daisy- chain appl ications require that only the units at each end of the daisy-chai n be terminated. All other peripherals on the chain must not be terminated. (See Figure 19).

Note. Remove drive terminator enabling jumper TE where terminators are not required. Removal of termina-

tor power source selection jumper TP (see Figure 7d) does not disconnect the terminator resistors from the circuit.

It is highly recommended that ANSI SCSI -2 Standard’s Alternative 2 termination (active termination) be used for applications with single-ended (“N” and “W” models), especially if the bus will be operated at transfer rates above 5 Mbytes/sec. The “N” and “W” models provide on-board active termination that can be disabled by removal of the enable jumper TE (see Figure 7d).

Note. ACTIVE TERMINATORS ARE HIGHLY RECOMMENDED FOR USE IN THE DAISY-CHAIN AS

DESCRIBED ABOVE. ACTIVE AND PASSIVE TERMINATORS SHOULD NOT BE MIXED ON THE SAME SCSI BUS.

Drive models “WC,” “LW,” and “LC” do not have internal ter m inators available. The user, systems integrator or host equipment manufacturer must provide a ter minator arrangement external to t he drive. For “LW ” models, terminator modu les can be purchased that plug between the SCSI I/O c able an d the dri ve I/O con nector o r on the end of a short I/O cable stub extending past the last cable connector.

Note. The S CS I protocol c hip drives the upper eight data and parity bits of the SCSI bus even when operat-

ANSI Standard X3T10/1143D contains additional details about SCSI bus terminator and terminator power requirements.

9.9 Terminator power “N” and “W” model drives

You can configure termin ator power in four different ways. See Section 8.1 for illustrat ions that s how how to place jumpers enabling each of the following terminator power configurations:

1. Drive accepts terminator power through SCSI bus pins: “N” models Pin 26 “W” models Pins 17, 18, 51, and 52

2. Drive supplies power to the SCSI bus.

3. Drive provides terminator power for optional internal terminator resistors using the drive’s power connector.

4. Drive provides power to its own terminators and to the SCSI bus terminator power line.

SCSI devices providing terminator power (TERMPWR) must have the following characteristics: 8-bit SCSI V TERM = 4.25 V to 5.25 V

800 mA minimum source drive capability

1.0 A maximum

16-bit SCSI V TERM = 4.25 V to 5.25 V

1,500 mA minimum source drive capability

3.0 A maximum

“WC” and “LC” model drives

These drives cannot furnish term inator power because no conductors in the 80-pin I/O connector are devoted to terminator power.

“LW model drives

You can configure terminator power from the drive to the SCSI bus or have the host adaptor or other device supply terminator power to the external term inator. See Section 8.1 for illustrations that show how to place jumpers for this configuration.
