Ethernet Interface
The MVME2300SC module uses Digital Equipment's DECchip 21143
PCI Fast Ethernet LAN controller to implement an Ethernet interface that
supports 10Base-T/100Base-TX connections, via an RJ45 connector on
the front panel. Ethernet AUI signals are routed to the P2 connector. The
balanced differential transceiver lines are coupled via on-board
transformers.
Every MVME2300SC is assigned an Ethernet station address. The address
is $0001AF2xxxxx, where xxxxx is the unique 5-nibble number assigned to
the board (i.e., every board has a different value for xxxxx).
Each MVME2300SC 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 the NVRAM (BBRAM) configuration area specified
by boot ROM. That is, the value 0001AF2xxxxx is stored in NVRAM. The
MVME2300SC debugger, PPCBug, has the capability to retrieve the
Ethernet station address via the CNFG command.
