IBM PS/2 MICRO CHANNEL SCSI ADAPTER WITH CACHE IBM Announcement Letter Number 192-067 dated March 24, 1992 IBM US - Last Revised on March 24, 1992 Brief Description of Announcement, Charges, and Availability IBM is announcing a redesigned version of the Personal System/2 (R) (PS/2 (R)) Micro Channel (R) SCSI Adapter with Cache (#1132, 6451133). This new version of the PS/2 Micro Channel SCSI Adapter with Cache eliminates the requirement to terminate the small computer system interface (SCSI) bus at the external port of the adapter, with no external devices attached. The PS/2 Micro Channel SCSI Adapter External Terminator (#1039, 6451039) is not required with the new adapter (#1132, 6451133). This 32-bit bus master SCSI adapter can be installed in either a 16- or 32-bit card slot; has 16.6MB burst transfer rate and 512KB cache buffer; and adheres to the industry standard SCSI interface that supports connection for multiple internal or external devices. IBM SCSI adapters provide the ability to connect SCSI high-performance fixed disk drives, scanners, printers, CD-ROMs and other SCSI peripherals. The IBM PS/2 Card to Option Cable (#1140, 6451139) provides the capability to attach the first external SCSI device to a Micro Channel SCSI adapter, and the PS/2 Option to Option Cable (#1042, 6451042) provides the capability to attach an external SCSI device to another external SCSI device. The PS/2 Micro Channel SCSI Adapter Option Interface Terminator, included with the PS/2 Card to Option Cable, is still required to terminate external SCSI connections and must be installed on the last external SCSI device.

PLANNING INFORMATION CABLE ORDERS: The PS/2 Card to Option Cable (#1140, 6451139) is a 60-pin to 50-pin cable that connects from the external connector of the adapter to the first external SCSI option, or other equipment manufacturer's device, that meets the ANSI SCSI STANDARD (X3.131-1986). The cable is approximately four feet (1,220 millimeters) in length. The PS/2 Option Interface Terminator, included with the PS/2 Card to Option Cable, is a 50-pin terminator that is connected to the last SCSI device to terminate the SCSI bus. The PS/2 Option to Option Cable (#1042, 6451042), is a 50-pin to 50-pin cable that connects one external SCSI device to another external SCSI device ("daisy chain" fashion), or other equipment manufacturer's device, that meets the ANSI SCSI STANDARD (X3.131-1986) for single-ended devices. The cable is approximately two feet (610 millimeters) in length. NOTE: Single-ended implementations are limited to a maximum distance of 20 feet (6 meters) between the SCSI devices at the end-to-end position on the SCSI bus. INSTALLABILITY: The SCSI adapter requires about 30 minutes to install. NOTE: SCSI devices have device IDs that may need to be set by the installer. The specific instructions are contained as part of the optional setup package. Device ID 6 is the IPL device if only SCSI devices are part of the system. This should be checked when installing additional devices on the SCSI adapter. PROBLEM DETERMINATION: The standard system error indications should be followed to resolve all problems. PACKAGING PRODUCT SHIPMENT GROUP PS/2 Micro Channel SCSI Adapter Card SCSI Adapter Reference Diskettes with Cache Installation Instructions SECURITY, AUDITABILITY AND CONTROL Security and auditability features of the system in which this product is installed are: o A mechanical lock to allow the user to lock the system cover o A user-invoked password function used to prevent use of the system by unauthorized persons. LIMITATIONS: SCSI, as defined in the American National Standard Institute (ANSI) standard X3.131-1986, provides a port for the attachment of external devices. The SCSI bus may be internal or external to the system unit. The IBM PS/2 SCSI adapters are in conformance with this standard and have an external port. A data security exposure exists even with Power-On Password installed, since external SCSI adapters can attach through the external SCSI port and gain undetected read or write access to data stored on internal and external SCSI devices. Physical access to the system and external SCSI devices must be controlled to limit this exposure. User management is responsible for evaluation, selection and implementation of security features, administrative procedures and appropriate controls in application systems and communications facilities.
