Section 1. General description The Seagate ST43400N/ND Elite 3 disc drives are high speed, random access digital data storage devices. They communicate with an initiator using the Small Computer System Interface (SCSI). The drive is shown in Figure 1, and its specifications are listed in Table 1 on the following page.
2 Table 1. Drive specifications Characteristics Conditions Specifications Size Dimensions See “Space requirements” in section 2 Weight (drive only) 3.
General description 3 continued from previous page Characteristics Conditions Specifications SCSI transfer rate, burst 10.0 Mbytes/sec max Seek time (time required to move heads to a different track address— excluding SCSI I/O overhead) Typical full 23.
4 The drive contains all the circuits and mechanical devices necessary to record data on and recover it from its discs. The drive requires DC voltage input from an external power supply, which receives its AC input power from the site main power source.

Section 2. Installation The information contained in this section describes installation and initial checkout of the drive. Site requirements The site requirements considered are environment, airflow, space, power, grounding, and interface. Environmental requirements All environmental requirements for the drive are listed in Table 2 below.
8 Airflow requirements The enclosure design must ensure adequate cooling for the drive. Note that the fan in the power supply cools only the power supply’s internal parts. The drive’s product specification (document 64403601) describes how to evaluate the airflow design.

24 Mounting the drive The drive may be secured to the enclosure via tapped holes in either the sides or the bottom of the drive chassis. Figure 10 shows two of the three allowable orientations. Note. The mounting screws must be completely engaged in the drive chassis, but the portion that extends into the chassis must not exceed 3.

26 Connecting the system I/O cabling Be sure that the site has been prepared in accordance with the site requirements information provided earlier in this section. This procedure describes how to cable the system in a daisychain configuration. This configuration was discussed earlier in this section under “Interface require- ments.
Installation 27 Figure 12 shows how the terminator resistor-paks are attached on drives with single-ended I/O. The terminator resistor-paks, which are single inline pack- ages, mount in the rows of holes located in the control board.
28 Figure 13 shows how the terminator resistor-paks are attached on drives with differential I/O. These terminator resistor-paks, which are dual inline packages, mount in sockets in the control board. These terminators are also marked with a dot above pin 1.

30 To enable the feature, it is necessary to run an additional daisychain cable from drive to drive and to make a master/slave selection for each drive. Connector J5 on the control board handles the cable connections. Master/slave selection is made by a jumper on connector J4A.
Installation 31 For each drive in the middle of the daisychain, the cable from the preceding unit connects to one of the two rows of pins (row A or row B), and the cable to the next unit connects to the other row of pins.
32 Verification After installing the drive, follow the sequence outlined below for initial startup. 1 . Place the on/standby switch in the on ( l ) position. What follows depends on the setting of the Start Command option and the Spinup Delay option jumpers on the control board.
Section 3. Operation This section provides the information and instructions to operate the drive. It includes the following topics: • Switches and indicators—locates and describes the switches and indicators used for normal drive operation. • Operating instructions—describes procedures for operating the drive.

Operation 35 Table 7. Switches and indicators Switch or Indicator Function Power supply On/standby switch Applies DC operating voltages to the drive electronics and (on/ ) power supply fan when placed in the on ( l ) position.
36 Operating instructions Following initial checkout, the drive normally requires no attention from the operator. DC power is available to the drive, as the on/standby switch on the power supply is normally left in the on ( l ) position.
Section 4. Parts data This section lists part numbers of options and accessories that can be used in a drive installation. Because the drive is depot repairable, there are no field- replaceable parts. If the drive requires maintenance, refer to the instructions in section 5.
38 Table 8 below lists the part numbers for options and accessories for system installation. Table 8. Options and accessories Part Number Description 12263496 Static ground wrist strap, 6 1/2 to 8 inc.
Section 5. Maintenance This section contains the following maintenance information: • Observing maintenance precautions • Arranging for depot repair • Removing and replacing a drive • Removing.
40 Arranging for depot repair Before returning any units to Seagate, it is necessary to obtain a returned material authorization (RMA) number. To get the number, you will need to know the part number and serial number of the unit. These numbers appear on a label located on the front surface of the HDA.
Maintenance 4 1 Removing and replacing a power supply To remove a power supply for maintenance, perform the following steps: 1. Remove power from the drive by setting the On/Standby switch on the power supply to the Standby position. 2. Disconnect the AC power cable from site power.
