Installation Requirements 3.2.4 Precautions on mounting (1) Mounting frame structure and clearance a) For vibration resistance and heat dissipation, mount this optical disk drive using a frame having an embossed structure shown in Figure 3.6 or a similar structure providing an equivalent function. b) A mounting screw must have an inward projection (entry depth) of 3 mm or less from the outer surface of the mounting frame of the optical disk drive as shown in Figure 3.6.
(2) Checking the panel function There must not be any deformation in the panel after the optical disk drive is installed in a cabinet. Make sure that the door of the disk insertion slot closes from any location with the drive installed in the cabinet. (3) Service areas Figure 3.7 shows the locations that need to be accessed for installation, and after installation is carried out.
FG are not shorted. Consequently, the static electricity tolerance is inferior to that realized when a metal frame is used. Fujitsu recommends using a metal frame. In particular, a metal frame must be used especially when high static electricity tolerance is required.
Figure 3.9 Power on/off sequence (1) b) In a system which does not use the terminating resistor power supply signal (TERMPWR) of the SCSI bus, the requirements for +5 VDC given in Figure 3.10 must be satisfied between the drive and the SCSI device with the terminating resistor circuit.
Installation Requirements (4) Power supply to SCSI terminating resistor If the power for the terminating resistor is supplied from the drive to other SCSI devices through the SCSI bus, the current-carrying capacity of the +5 VDC power supply line to the optical disk drive must be designed with consideration of an increase of up to 900 mA.

4.4.2 Mounting procedure How the drive is mounted depends on the system cabinet structure. Determine the mounting procedure in consideration of the requirements of each system. This section contains the general mounting procedure and check items. See Section 3.2 for details on mounting drive. 1) For a system with an external operator panel mounted, connect the external operator panel cable before mounting the drive in the system cabinet because it is difficult to access the connector after the drive is mounted.
Installation 4) After each cable connector is connected, secure the cable so that the cable does not touch the drive or the parts on the PCA or obstruct the flow of cooling air in the system cabinet. 1) Be careful of the insertion directions of SCSI connectors. For a system in which the terminating resistor power is supplied via the SCSI cable, connecting connectors in the wrong direction may cause the following:...
4.6 Operation Confirmation and Preparation for Use after Installation The BUSY LED is on while the optical disk drive is executing seek, write, or read operations. The BUSY LED is on momentarily, so it seems as if it blinked or is off. The eject motor turns once when the power is turned on so that in case the spindle motor position deviates due to shocks received by the drive during transport the position is corrected to allow the...
(2) If processing terminates abnormally: a) If sense data has been obtained by the REQUEST SENSE command, analyze the sense data. If the error is recoverable, retry the processing. b) Check the following items for SCSI cable connection: All connectors, including other SCSI devices, are connected correctly. A terminating resistor is correctly mounted at both ends of the cable.
CHAPTER 5 Operation and Cleaning Operation of Optical Disk Drive Cleaning of Optical Disk Drive Operation of Optical Disk Cartridge Cleaning of Optical Disk Cartridge This chapter describes how to operate and clean the optical disk drive and an optical disk cartridge. 5.1 Operation of Optical Disk Drive The optical disk drive has automatic load and eject functions.
Operation and Cleaning 1) Disk insertion slot Insert and eject an optical disk cartridge into and out of this slot. 2) Eject button & BUSY LED (indicator lamp) On this optical disk drive, the eject button serves also as the BUSY LED (indicator lamp).
3. If the BUSY LED indicator lamp does not go on after a cartridge is inserted, press the eject/BUSY LED button once to eject the cartridge and insert it again. 4. Do not forcibly insert a cartridge if you have any difficulty inserting it. If you do, the drive may be damaged.
Operation and Cleaning If you insert an optical disk cartridge with the printed shutter facing upward by pressing on the rear of cartridge at the left edge, you may hear an audible click but the drive may not become READY. In such a case, press the cartridge further by pressing on the back of the cartridge from the center (somewhere near the notched section of the panel front) until the LED indication lamp goes on.
Figure 5.3 Removing an optical disk cartridge 5.2 Cleaning of Optical Disk Drive The drive performance may deteriorate if dust, particle or cigarette smoke deposits accumulate on the lens actuator of the drive. Clean the lens actuator periodically using following head cleaner (*1). *1 How often the lens actuator should be cleaned varies depending on the environment in which the optical disk drive has been installed.
Operation and Cleaning Device Damage: Be sure to use the dedicated head cleaner shown above. Check the state of the cleaning brush by opening the shutter of the head cleaner. If the tips of the brush bristles are spread out, the lens cannot be completely cleaned.

Operation and Cleaning 5.3.2 Write protect tab Move the write protect tab to enable or disable writing to an optical disk cartridge. Use a fingernail or something similar to move the write protect tab (it must be completely moved to one end because there is some play in the middle). Figure 5.5 shows where the write protect tab is located on a optical disk cartridge and how the write protect tab should be moved (see the Write Enabled and Write Disabled indications printed on the label).
5.3.3 Precautions To maintain the performance and reliability of an optical disk cartridge, keep the following points in mind when using, storing, or transporting an optical disk cartridge: (1) Using a cartridge Do not use a cartridge in an environment where it is exposed to direct sunlight or sharp temperature changes, or high temperature or humidity.
Operation and Cleaning 5.4 Cleaning the Optical Disk Cartridge You must periodically clean an optical disk cartridge because the accumulation of dust, particle, or cigarette smoke deposits on the disk lowers the performance of the cartridge. How often the cartridge should be cleaned varies depending on the environment in which the optical disk drive has been installed.
Clean an optical disk cartridge as follows: Disk damage: Clean a cartridge in a dust-free environment. Fujitsu recommends wearing disposable gloves during cleaning so that no fingerprints are left on a disk. 1) Slide the cartridge shutter until it is completely open (see Figure 5.6).
Operation and Cleaning Spindle Setting case lid Figure 5.7 Setting an optical disk cartridge into the setting case Disk damage: Do not press hard or apply excessive shock to an optical disk cartridge case while setting it in the setting case. 3) Place the setting case cover over the cartridge while inserting the disk revolving knob pin into the center hub of the cartridge (see Figure 5.8).
Eye inflammation: If the cleaning solution gets into your eyes, immediately wash the solution away with water. 6) Gently wipe the disk surface, going from the center to the edge of the disk. 7) After wiping, turn the disk-revolving knob and then wipe the next section in the same manner (see Figure 5.9).
CHAPTER 6 Diagnostics and Maintenance Diagnostics Maintenance Information This chapter provides diagnostics and maintenance information. 6.1 Diagnostics Table 6.1 lists test items during diagnostics. The optical disk drive has a self-diagnostics function. This function can check the normality of basic operations of the drive. To check the generation operations including the operations of the interface with the host system, provide a test program that can run in the host system (see Section 6.1.3).
(3) Service system and repair Fujitsu provides a service system and repair facility for its optical disk drives. Submit to your Fujitsu representative information required to replace or repair a drive. Normally, the information includes:...
However, you do need to include a cartridge if errors keep occurring with a specific cartridge. In such a case, be sure to save data stored in the cartridge before sending it in. Fujitsu shall bear no responsibility for any data lost during service or repair.
(see Figure 6.2). If a revision number is changed after shipment, Fujitsu issues "Revision Number Change Request/Notice" to indicate the new revision number. The user must update the revision label as described above after applying the change.

SCSI BUS 7.6 Bus Phases The SCSI bus must be in one of the following eight phases: BUS FREE phase ARBITRATION phase SELECTION phase RESELECTION phase COMMAND phase DATA phase STATUS phase MESSAGE phase The SCSI bus can never be in more than one phase at any given time. Note: In the following bus phase definition, signals are false unless otherwise defined.
Bus Settle Delay (Min) Transition to a BUS FREE phase occurs when the TARG stops the BSY signal in one of the following events: When the RESET condition has been detected When the TARG has received ABORT message When the TARG has received a BUS DEVICE RESET message When the TARG has sent a DISCONNECT message normally When the TARG has sent a COMMAND COMPLETE message normally If a SELECTION or RESELECTION phase is terminated unsuccessfully, the...
SCSI BUS 7.6.2 ARBITRATION phase The ARBITRATION phase allows one SCSI device to gain control of the SCSI bus so that an INIT starts the SELECTION phase or a TARG starts the RESELECTION phase. Implementation of the ARBITRATION phase is a system option. This phase is required for system that has two or more INITs or uses the RESELECTION phase.
SCSI BUS 7.6.3 SELECTION phase An INIT can select a TARG in the SELECTION phase. Note: I/O signal is false during a SELECTION phase. (The I/O signal identifies the phase as SELECTION or RESELECTION). (1) Start sequence without ARBITRATION phase In systems with the ARBITRATION phase not implemented, the INIT starts the SELECTION phase in the following sequence (See Figure 7.11).
SCSI BUS (4) Timeout procedure If the INIT cannot detect the response from TARG when the Selection Timeout Delay (or longer) has passed after starting the SELECTION phase, the timeout procedure shall be performed through one of the following schemes: The INIT asserts the RST signal and creates the RESET condition.
Bus Clear Delay + Bus Settle Delay (Min) Figure 7.12 (2) Response sequence When the SCSI device (INIT) detects that the SEL signal, I/O signal and data bus bit (DBn) corresponding to the own SCSI ID are true and the BSY signal is false for Bus Settle Delay or more, the INIT shall recognize that the INIT itself is selected in the RESELECTION phase.
SCSI BUS (3) Timeout procedure If the TARG cannot detect a response from the INIT when the Selection Timeout Delay or longer has passed in the RESELECTION phase, the timeout procedure shall be performed though one of the following schemes: 1) The INIT asserts the RST signal to generate the RESET condition.

Bus Settle Delay (Min) Figure 7.13 INFORMATION TRANSFER phase (phase control) 1. After the ACK signal becomes false during the INFORMATION TRANSFER phase, the TARG can begin to prepare for a new phase by changing the status of C/D, I/O, and MSG signals.
Page 130
SCSI BUS (1) Asynchronous transfer In asynchronous transfer mode, information transfer is controlled by the INIT and TARG which are checking the status transition (from false to true and vice versa) of REQ and ACK signals (interlock type). Asynchronous transfer can be used in all types of INFORMATION TRANSFER phase (COMMAND, DATA, STATUS, MESSAGE).

SCSI BUS (2) Synchronous mode Information is transferred through offset-interlock of REQ/ACK handshake. Operation in this mode is only available for the DATA phase. The default data transfer mode is asynchronous mode. When power is first switched on, a RESET condition develops or a BUS DEVICE RESET message is exchanged, data transfer is performed in asynchronous mode until the message described below is exchanged, even if synchronous mode transfer is permitted with the...

The minimum pulse width is Assertion Period. The minimum period between the trailing edge of a pulse and the leading edge of the next pulse is Negation Period. The period between the leading edges of a pulse and the next pulse is equal to or greater than the time defined by the Transfer Period parameter.
Page 134
SCSI BUS 4) Starting with the rise of the ACK pulse, the TARG reads data on the data bus (DB7 to DB0, P) within the Hold time. (3) Time monitoring of ACK response wait When the ODD operates as a TARG, wait time for ACK response to REQ can be monitored.
7.6.6 COMMAND phase The COMMAND phase is a bus phase in which the TARG requests the INIT to transfer command information (CDB) to the TARG. The TARG keeps the C/D signal true and the I/O and MSG signals false during REQ/ACK handshaking in this phase.
Page 136
SCSI BUS Figure 7.16 (4) Data transfer rate in synchronous mode Table 7.9 lists parameters for synchronous data transfer that can be performed by the ODD. Values assigned to these parameters are determined by SYNCHRONOUS DATA TRANSFER REQUEST messages transferred between the INIT and TARG.
1) If (n T1) (T2 + 700), Average data transfer rate in SCSI = 1000/T1 (MB/s) 2) If (n T1) (T2 + 700), Average data transfer rate in SCSI = (n 1000)/(T2 + 700) (MB/s) where, n: Value assigned to REQ/ACK Offset parameter T1: Value in ns assigned to Transfer Period parameter (see Table 7.9) T2: Average time in ns from REQi pulse transmission to corresponding ACKi response at the pertinent pins of the SCSI connector on the ODD...
If the message consists of more than one byte, all bytes must be transferred in a single MESSAGE phase. For details of message types and their operation, see Chapter 5, "MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS Optical Disk Drives SCSI Logical Interface Specifications."...
Unless a parity error is detected, the TARG can execute the received message immediately after its reception. If a parity error is detected, the TARG ignores that part of the message which has been received after the detection of the parity error.
ODD executes the timeout process (see Subsection 7.6.4) to free the SCSI bus and then executes the retry process (see Section 6.1) of the RESELECTION phase in "MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS Optical Disk Drives SCSI Logical Interface Specifications." (2) Time monitoring in INFORMATION TRANSFER phase The ODD monitors the timing of the ACK signal against the REQ signal in the INFORMATION TRANSFER phase.
When timeout is detected, the ODD clears the command being executed and forces the SCSI bus into the BUS FREE phase (see Section 6.1) in "MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS Optical Disk Drives SCSI Logical Interface Specifications." Table 7.10 Setting value of SCSI time monitoring...
The INIT must make the ATN signal false before making the ACK signal true to transfer the last message byte if so specified for the particular type of message to the TARG. (See "MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS Optical Disk Drives SCSI Logical Interface Specifications.")
Page 143
(2) Response against ATTENTION condition (TARG) The TARG must enter the MESSAGE OUT phase and respond to the ATTENTION condition under the following situations. After terminating the MESSAGE OUT phase and sending back a MESSAGE REJECT message, the TARG must reenter the MESSAGE OUT phase if the ATN signal is true. When the ATN signal becomes true in the COMMAND phase, the TARG must initiate the MESSAGE OUT phase immediately after the command (command descriptor block [CDB]) has completed the transfer of all or some...
The ATTENTION condition generated by the INIT in the SELECTION phase determines the message level to be used in the command execution sequence. (Details are explained in Subsection 5.1.3. of “MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS OPTICAL DISK DRIVES SCSI LOGICAL INTERFACE SPECIFICATIONS.”) If the ATTENTION condition is not generated in the SELECTION phase, the TARG uses a COMMAND COMPLETE message only.
Page 145
All SCSI devices must deactivate all the bus signals except RST signals and release the bus within 800 ns (Bus Clear Delay) after the RST signal becomes true. After the RESET condition, the SCSI bus must enter the BUS FREE phase. Figure 7.20 shows the RESET condition.
7.8 Bus Sequence SCSI bus phases are switched in the specified sequence according to the command operation executed in the TARG. After a TARG has asserted the BSY signal in the SELECTION or RESELECTION phase, the bus phase sequence other than ATTENTION condition and RESET condition is controlled by the TARG.
