Deskstar SCSI-2 Fast (DALS-3540)
Electrical interface specifications |
Electrical connector locations |
 |
 |
The DC power connector is designed to
mate with AMP part 1-480424-0 (using AMP pins P/N 350078-4).
Equivalent connectors may be used. Pin assignments are shown below,
as viewed from the end of the drive. |
 |
| SCSI signal connector |
The SCSI Signal Connector is a 50 pin
connector meeting the ANSI SCSI specification. |
 |
| Note: It is intended that the
hard disk drive should only be in electrical contact with the
chassis of the PC at a designated set of mounting holes. Other
electrical contact may degrade error rate performance. As a result
of this it is recommended that there should be no metal contact to
the hard disk drive except at the mounting holes or the side rails
into which the mounting holes are tapped. |
SCSI cable |
The disk drive uses single-ended drivers
and receivers which will permit cable lengths of up to 6 meters
(19.68 feet). For a single ended cable a 50 conductor flat cable or
a 25 signal twisted cable can be used with a maximum length of 6.0
meters, and a stub length not exceeding 0.1 meters. |
SCSI bus terminator |
The drive has an internal active SCSI
bus terminator, and can be controlled on/off with one jumper block
provided at the card edge. The user is responsible for properly
terminating and powering the SCSI bus in the system. |
