The existence and defintion of these pins are model dependent. +-D32------------------------------------------------------------D1-+ ++ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ++ | * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * | X| * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * |X | * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * | +A32------------------------------------------------------------A1+ (Electrical connectors (rear and top view) - CxC models) Unitized Connector ------------------ 1 -MFG Programmable GND Test +--+ +5V (long) -SYNC Mode +--+ | +---9-----7-----5-----3------1-----+ | | | 8 = -Device Fault | +--10-----8-----6-----4------2-----+ | 4 = -Write Protect +--+ -Device -Auto Start+ Programmable Activity 2 (long) +-------+GND +3.3V +------ +----+ |15 13 11 9 7 5 3 1 | +--- | +------------------------------------------+ | | +------------------------------------------+ | +--+16 14 12 10 8 6 4 2 +--+ GND +3.3V (long) 11 = -Power Fail 12 = Gnd (long) 09 = +5V 10 = Gnd (long) 07 = Gnd (long) 08 = Gnd (long) 05 = +12V 06 = +12V 03 = Gnd (long) 04 = Gnd (long) 01 = +12V Charge (long) 02 = +5V Charge (long) The unitized connector is located on the left side of the top view (bottom drawing). The jumper connector is located on the right side of the top view (bottom drawing). This jumper connector is referred to as front jumper because of its front location. It is reserved for IBM engineering use only. Manufacturing test mode (option port pin 1) ------------------------------------------- A low active input pin, that when active (pulled below 0.8V) makes pin 2, 3, 4, 6, 8, 9 and 10 available to be redefined. Pins 5 and 7 must remain ground and +5V respectively. One possible purpose for this pin is to allow a manufacturing tester to redefine the option pins to what ever function it desires, while allowing the shipped product to return to the standard product definitions in the customer environment. All models (CxC and CxB) reserve this pin but it is not connected to any internal logic. Auto start pin (option port pin 2) ---------------------------------- A low active input pin, that when active (pulled below 0.8V) on CxC model causes the drive motor to spin up and become ready for media access operations after power is applied without the need to receive a start/stop unit command. When inactive (pulled above 2.0V), the drive motor shall not spin up until after the receipt of a start/stop unit command. The signal is set to be sampled by the device at power on, or hard reset or soft reset conditions. This pin is not accesible on CxB models. Sync pin (option port pin 3) ---------------------------- Th esync input/output pin on CxC model can be used for synchronizing among devices. The synchronization is achieved by having one device use this pin as an output to transmit one sync character one per its spindle revolution. The other node may use this pin as an input and synchronize their spindle revolution position to match the sync signal. The SSA network provide sync character over SSA link, but this option pin allows synchronization across multiple SSA networks, or allow tighter latency of the sync pulse. The width, period, and tolerance of the negative active sync pulse is manufacturer dependent, and thus synchronization across different manufacturers or even different product lines of the same manufacturer is not guaranteed. The sync pin usage is controlled by mode pages within the mode select command. This pin is not accessible on CxB model. Write protect pin ----------------- The write protect pin is a low active pin, thatz when active (pulled below 0.8V) the drive will prohibit commands that alter the customer data area portion of the media from being performed. The state of this pin is monitored on a per command basis. This pin is not accessible on CxB model. Ground long (option port pin 5) ------------------------------- The ground long output pin on CxC models can be used to drive an external light emitting diode. CxB models have an integrated green LED. CxC models provide up to 24 mA of TTL level LED sink current capability. Current limiting for the LED is provided on the electronics card. The anode may be tied to the +5V power source (provided on the unitized connector). The LED cathode is then connected to the device activity pin to complete the circuit. +5V (option port pin 7) ----------------------- The +5V output pin on CxC and CxB models shall supply up to 1.0Amp of current limited +5V ( 10%), as long as power is supplied to the device. Device fault pin/indicator (option port pin 8) ---------------------------------------------- The device fault pin on CxC models can be used to drive an external light emitting diode. CxB models have an integrated amber LED. CxC models provide up to 24 mA of TTL level LED sink current capability. Current limiting for the LED is provided on the electronics card. The anode may be tied to the +5V power source (provided on the unitized connector). The LED cathode is then connected to the device fault pin to complete the circuit. Programmable pin 1 (option port pin 9) -------------------------------------- This pin can be used by a manufacturer for whatever purposes it desires within the specified definition, electrical characteristic and the availability of microcode. This pin is completely controlled by microcode. This pin is not accessible externally on CxB models. Programmable pin 2 (option port pin 10) --------------------------------------- This pin is reserved and is not connected to any internal logic. This pin is not accessible externally on CxB models. Early power off warning or power fail (power port pin 11) --------------------------------------------------------- The early power off warning input pin on CxC models can be used to indicate to the drive that a power loss will occur by pulling this signal above a 2.0 volt threshold. The input must provide a minimum of 6 milliseconds warning before power falls below operating specifications in order for the drive to stop its activities and handle the fault. This pin is not accessible on CxB models. 12V charge and 5V charge (power port pin 1 and 2) ------------------------------------------------- These pins are longer than the others. They help to reduce current spikes during hot plug. Each pin requires a resistor (not in the drive) in series between the power source and the drive connector. This allows for more controlled current draw as prior to other voltage pins. It is up to the subsystem to determine the proper resistance to add to these pins to meet the 10% voltage drop limitations and the current draw limitation of the connector. These pins are not accessible on CxB models. Front jumper connector ---------------------- All models contain a jumper block that is reserved for IBM engineering use only. SSA unitized connector ---------------------- Electrical connections for CxC models are provided by a single connector mounted on the rear of the drive. Connections are provided for two SSA port, fault sensors and indicators, option customization and power. ********************************************************************** I N S T A L L ********************************************************************** IBM DFHC ULTRASTAR XP SS NOTES ON INSTALLATION Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Carrier connector ----------------- Electrical connections for CxB models are provided by a single 128 pin connector on the rear of the drive. Connections are provided for two SSA ports, fault sensors and indicators, and power. The receptacle used is a 4 x 32 female contact, BERG HPC connector, IBM part number 99F9429. Clearances ---------- A minimum of 2 mm should be given to the bottom surface except for a 10 mm diameter area around the bottom mounting holes. For proper cooling it is suggested that a clearance of 6 mm be provided under the drive and on top of the drive. There should be 7 mm of clearance between drives that are mounted with their top sides facing each other. Mounting CxB ------------ The carrier is designed to be plugged into an auto-docking assembly. The auto-docking assembly contains an electrical receptacle that provides connections for DC power, SSA interface signals, and fault sensing and reporting signals. The carrier design allows for positive retention of the carrier in all axes when plugged into the auto-docing assembly. In addition, the carrier retention provides a force to bottom out the carrier auto-docking connector into the auto-docking assembly and maintain a force of 5 pounds minimum, 40 pounds maximum. The mating connector should contain two guide pins to align the carrier receptacle during seating. These guide pins are BERG part number 77693-014 (IBM part number 72G0343) or AMP equivalent part number 1-532808-1 (IBM part number 19G6789). The guide pin length should be 26.04mm while the thread depth depends upon the thickness of the circuit board the connector is mounted to. The guide pins should be tied to the docking assembly frame ground. NOTE The connector pins must be lubricated to insure seating of the carrier into the auto-docking assembly. The type of lubricant recommended is Stauffer CL-920 or equivalent. The maximum allowable penetration of the mounting screws is 3.8 mm. The torque applied to the mounting screws must be 0.8 newton meters 0.1 Newton meters. Grounding requirements of the disk enclosure --------------------------------------------- The disk enclosure is at power supply ground potential. It is allowable for the user mounting scheme to common the disk enclosure to frame ground potential or leave it isolated from frame ground. The drive's mounting frame must be within 150 millivolts of the drive's power supply ground. At no time should more than 35 milliamps of current (0 to 100 MHz) be injected into the disk enclosure. ********************************************************************** F E A T U R E S ********************************************************************** IBM SSA SSA --- Serial Storage Architecture (SSA) is a powerful high-speed serial interface designed to connect high-capacity data storage devices, subsystems, servers and workstations. Designed with the future in mind, SSA facilitates migration from current SCSI equipment and will accommodate implementation of future configurations, including the use of fiber-optic connections. IBM offers SSA interfaces on its 3.5-inch line of Ultrastar XP and Ultrastar 2XP high-performance drives. SSA reduces interface costs. No external drivers or receivers required; these functions are embedded within a CMOS protocol chip. Only four signal wires are required, compared to 68 for the closest SCSI equivalent. SSA interface require no address switches and no discrete terminators. SSA architecture operates at two protocol levels. The lower level, SSA-PH, defines the electrical characteristics, coding scheme and method of information transmission. The upper level maps SCSI commands into a form suitable for serial transmission. As a result, devices now using SCSI-2 can be upgraded to SSA with minimal code changes. SSA offers superior performance over the interfaces commonly used today. Each SSA link is full-duplex and frame multiplexed simultaneously, resulting in data rates in the 20MB/sec range in each direction, with total throughput of 80MB/sec at each node. As many as 127 devices can be connected per loop, with "hot plugging" supported. The combination of low power, fewer components and fault isolation makes SSA highly reliable. Each node performs extensive error checkig, and if errors occur, SSA provides transparent frame recovery. When SSA devices are configured in a loop, alternate paths to each device ensure that there is no single point of failure.
