IBM OEM Storage Products Deskstar DALS-3540 IBM introduced a disk drive for the desktop personal computer marketplace. It was available at the 540 MB capacity point with SCSI-2 FAST interface, the drive provided excellent performance and improved reliability. APPLICATIONS Desktop personal computers Low end workstations Storage expansion applications FEATURES 541 MB Formatted capacity (512 byte/sector) 10 MB/s data transfer speed 48.7 Mb/s (OD) media data rate 32.2 Mb/s (ID) media data rate Average seek time 12 ms (read) 4500 RPM 64 KB segmented buffer Read ahead caching with LFU (Least frequently used) segment update Industry standard mounting The drive can be mounted with any of its six surfaces facing down Advanced ECC on the fly Power saving modes Robust design for EMC/RFI MR (Magneto Resistive) head technology No-ID sector format MTBF 350,000 hours BENEFITS Generic popular storage capacity Fast interface data rate Excellent performance on long records Fast access to data Ease of installation Improved data throughput Reduced power consumption Ideal for energy-efficient systems Easy integration across multiple platforms High area density, low component count More data stored per track, increased sustained data transfer rate Assured reliability Pin 1 SCSI I/F Power Connector Connector Pin 2 CONNECTORS Power Connector Back Side of Drive SCSI I/F Logic Connector Card JP 12 Option Block JP 1 Bottom of drive Pin# 1 2 3 4 +5V GND GND +12V 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 mounti
