2 Gbyte Standard Connector Disk Drive Installation Manual—May 1995

1

The drive is a standard connector, 2.1 Gbyte SCSI low profile disk drive. It is
approximately 1 inch high and 3.5 inches wide. It supports fast SCSI at
10 Mbytes per second.

When you examine your 2.1 Gbyte disk drive, locate the label that has the Sun
part number to determine which vendor manufactured it. Disks with the
370-2067 part number are manufactured by Seagate, disks with the 370-1957
part number are from IBM. While all performance specifications are the same
for both drives, the jumper locations and settings are different. Once you have
identified which drive you have, follow the instructions for that specific drive
only.

Mounting Hardware

When you unpack the disk drive, remove the plastic bags that contain various
mounting brackets, screws, grommets and cables. The bags are labeled:

•

Multi-Disk Pack

•

Desktop Disk Pack

Open only the appropriate bag for your system. Put the other bags aside.
