The ±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initiator. the +12V current profile in the Elite 47 Product Manual (publication number 83329280). condition occurs when the Motor Start option is enabled and the drive has not yet received a Start Motor command. 2A 3 See 4 This 5 See "Conducted noise immunity" in the Elite 47 Product Manual.

Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device. 10 No terminator power.

B 19 SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system's SCSI controller usually uses the ID that has the highest priority interrupt in the SCSI I/O system. The lower priority SCSI IDs are normally used for other SCSI devices such as this Elite 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. This drive is a SCAM (SCSI Configured Auto Magically) compliant drive. If the system into which you are installing this drive requires SCAM compliant drives, you do not need to be concerned about the drive ID jumper settings, as the system automatically assigns your new drive the ID it wants it to have. Setting the drive ID doesn't hurt anything, but is not necessary in a SCAM compliant system. 20 Elite 47 Installation Guide, Rev. B Most Elite 47 disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, install jumpers on the appropriate pins as shown in Figure 2. J4A Pin 1 SCSI ID = 0 (default) SCSI ID = 1 SCSI ID = 2 SCSI ID = 3 SCSI ID = 4 SCSI ID = 5 SCSI ID = 6 SCSI ID = 7 SCSI ID = 8* SCSI ID = 9* SCSI ID = Ah (10)* SCSI ID = Bh (11)* SCSI ID = Ch (12)* SCSI ID = Dh (13)* SCSI ID = Eh (14)* SCSI ID = Fh (15)* Pin 15 Pin 1 J4A J01 J6 SCSI I/O Connector DC Power Connector J4B Pin 1 Figure 2. Setting the SCSI ID 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 Elite 47 Installation Guide, Rev.

Signal ground on the printed circuit board assembly (PCBA) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. Ensure the equipment in which you have mounted the drive is connected directly to the HDA. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions.
