Each board has an Ethernet Station Address displayed on a label attached
to the VMEbus P2 connector. In addition, the six bytes including the
Ethernet address are stored in the configuration area of the BBRAM. That
is, 08003E2XXXXX is stored in the BBRAM. At an address of
$FFFC1F2C, the upper four bytes (08003E2X) can be read. At an address
of $FFFC1F30, the lower two bytes (XXXX) can be read. The MVME162
debugger has the capability to retrieve or set the Ethernet address.
If the data in the BBRAM is lost, the user should use the number on the
label on backplane connector P2 to restore it. The Ethernet transceiver
interface is located on the controller's main circuit board, and the industry
standard connector is located on its front panel.
Support functions for the 82596CA are provided by the MCchip ASIC.
Refer to the 82596CA user's guide and to the MCchip in the MVME162LX
Embedded Controller Programmer's Reference Guide for additional
programming information.
SCSI Interface
The controller 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 53C710 are provided by the MCchip ASIC. The
SCSI connector is located on the controller's front panel.
Refer to the NCR 53C710 user's guide and to the MCchip in the
MVME162LX Embedded Controller Programmer's Reference Guide for
additional programming information.
SCSI Termination
The individual configuring the system must ensure that the SCSI bus is
properly terminated at both ends. SCSI bus terminators are located on the
controller. The SCSI terminators are enabled/disabled by a jumper on
header J14. If the SCSI bus ends at the controller, then a jumper must be
installed between J14 pins 1 and 2.
