ICS TRIPLEX T3419 Redundant channel module

The MVME2603/2604 VME module uses Digital Equipment’s DECchip 21140 PCI Fast Ethernet LAN controller to implement an Ethernet interface that supports both AUI (via MVME712M) and 10BaseT/100BaseTX (via MVME761) connections. The balanced differential transceiver lines are coupled via on-board transformers.Every MVME2603/2604 is assigned an Ethernet station address. The address is $08003E2xxxxx, where xxxxx is the unique 5-nibble number assigned to the board (that is, every board has a different value for xxxxx). Each MVME2603/2604 displays its Ethernet station address on a label attached to the base board in the PMC connector keepout area just behind the front panel. In addition, the six bytes including the Ethernet station address are stored in an SROM off the DECchip Ethernet controller, that is, the value 08003E2xxxxx is stored in SROM. At an offset of $1F2C, the upper four bytes (08003E2x) can be read. At an offset of $1F30, the lower two bytes (xxxx) can be read. The MVME2603/2604 debugger, PPCBug, has the capability to retrieve or set the Ethernet station address via the CNFG command

The unique Ethernet address is set at the factory

and should not be changed. Any attempt to change this address may create node or bus contention and thereby render the board inoperable. If the data in SROM is lost, use the number on the label in the PMC connector keepout area to restore it. For the pin assignments of the transition module AUI or 10BaseT/100BaseTX connector, refer to the user’s manual for the MVME712M or MVME761 (listed in Appendix D, Related Documentation) respectively. Refer to the BBRAM/TOD Clock memory map description in the MVME2600 Series Single Board Computer Programmer’s Reference Guide, listed in Appendix D, Related Documentation, for detailed programming information.

PCI Mezzanine Interface 

A key feature of the MVME2603/2604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the on-board local bus devices (SCSI, Ethernet, graphics, etc.), the PCI bus supports an industrystandard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card). PMC modules offer a variety of possibilities for I/O expansion through FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer Mode), graphics, Ethernet, or SCSI ports. The base board supports PMC front panel and rear P2 I/O. There is also provision for stacking a PMC carrier board on the base board for additional expansion.
