[. . . ] The specified voltage tolerance is inclusive of ripple, noise, and transient response. power-up, the motor current regulator limits the +12V current to an average value of less than 1. 4A, although instantaneous peaks may exceed this value. current loading for each supply voltage is not less than 4% of the maximum operating current shown. separate ground returns for +5V and +12V supplies. 6 At 7 Minimum 8 Use 9 Where power is provided to multiple drives from a common supply, carefully consider individual-drive power requirements. Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device. A command is issued every 0. 075 seconds (every 0. 063 seconds on wide and SCA drives). 10 Operating Barracuda 9 Installation Guide, Rev. power-saving features are enabled; ASA II code only. 12 All 13 Seeking is defined as a third-stroke seek at OD. track is defined as repeat reads of track 15 with a duty cycle of: 78% for N drives, 32% for W drives, 48% for WC drives, 44% for WD drives, and 44% for DC drives. 14 Read 20 Barracuda 9 Installation Guide, Rev. B Initial setup information The general information beginning on this page applies to all of the Barracuda 9 drive models. After reading the general information topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model. Drive models ST19171N ST19171W ST19171WC ST19171WD ST19171DC Page 32 36 41 General information The following general information topics are discussed: · · · · · · · · SCSI ID jumpers Drive termination Terminator power Interface drivers and data path width notes Other applicable jumper options Providing adequate cooling Mounting the drive and connecting cables* Formatting the drive *This mounting procedure does not apply to WC or DC model drives. To mount a WC or DC drive, plug the drive into the system's single connector attachment (SCA) position on the system's back panel. Barracuda 9 Installation Guide, Rev. B 21 SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system's SCSI controller usually uses the highest-numbered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive. Other controllers do not allow this so be sure to refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. To change the SCSI ID, refer to the appropriate drive section for your model. If, after completing the installation process, the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Barracuda drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI "device" is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus. 22 Barracuda 9 Installation Guide, Rev. B The top example in Figure 2 shows an internal hard disc at one end of the SCSI bus with the SCSI controller at the other end (both are terminated). The bottom example shows two additional SCSI devices connected externally--this means the SCSI controller is no longer on the end of the SCSI chain and should not be terminated. Some controllers prefer to remain terminated even if they are in the middle of the chain. [. . . ] If you install the drive on the end of the SCSI bus, enable termination by installing a jumper on pins 15 and 16 of connector J2 (see Figure 11). Use active (ANSI SCSI-2 Alternative 2) terminators when terminating the bus. ST19171WD drives do not have internal terminators or any other way of adding internal termination to the drive. You must provide external differential termination to these drives when termination is required.
