Scsi Interface; Scsi Termination; Local Resources - Motorola MVME162 User Manual

If the data in the BBRAM is lost, use the number on the label on backplane
connector P2 to restore it.
The Ethernet transceiver interface is located on the MVME162 main module.
An industry-standard DB15 connector is located on the MVME712 series
transition module.
The MCchip provides support functions for the 82596CA. Refer to the
82596CA user's guide and to the MVME162 Embedded Controller Programmer's
Reference Guide for detailed programming information. Refer to the
MVME712-12, MVME712-13, MVME712A, MVME712AM, and MVME712B
Transition Modules and LCP2 Adapter Board User's Manual or the MVME712M
Transition Module and P2 Adapter Board User's Manual for the pin assignments
of the transition module Ethernet connectors.

SCSI Interface

The MVME162 supports mass storage subsystems through the industry-
standard SCSI bus. These subsystems may include hard and floppy disk
drives, streaming tape drives, and other mass storage devices. The SCSI
interface is implemented using the NCR 53C710 SCSI I/O controller.
Support functions for the NCR 53C710 are provided by the MCchip. Refer to
the NCR 53C710 user's guide and to the MVME162 Embedded Controller
Programmer's Reference Guide for detailed programming information. Refer to
the MVME712-12, MVME712-13, MVME712A, MVME712AM, and
MVME712B Transition Modules and LCP2 Adapter Board User's Manual or to the
MVME712M Transition Module and P2 Adapter Board User's Manual for the pin
assignments of the transition module SCSI connectors.

SCSI Termination

The individual configuring the system must ensure that the SCSI bus is
properly terminated at both ends.
The MVME162 provides sockets for SCSI bus terminators on the P2 adapter
board or the LCP2 adapter board. If the SCSI bus ends at the adapter board,
then termination resistors must be installed on the adapter board. +5V power
to the SCSI bus
through a fuse located on the adapter board.

Local Resources

The MVME162 includes many resources for the local processor. These include
tick timers, software programmable hardware interrupts, watchdog timer,
and local bus timeout.
