Request 6 (PARBI6) Ethernet Port 2 (Front Panel or P2)
The MVME5100 provides dual Ethernet interfaces (Port 1 and Port 2) via
two pairs of Intel GD82559ER Fast Ethernet PCI controller chips. Port 1’s
10BaseT/100BaseTx interface is routed through the front panel. Port 2’s
Ethernet interface is routed to either the front panel or the P2 connector, as
configured by jumpers. The front panel connectors are RJ-45. Every
MVME5100 board is assigned two Ethernet Station Addresses. The
address is $0001AFxxxxxx, where xxxxxx is the unique number assigned
to each interface. The higher Ethernet Station Address corresponds to Port
1 and the lower Ethernet Station Address corresponds to Port 2. The
Ethernet Station Addresses are displayed on labels attached to the PMC
front-panel keep-out area. In addition, the presence of the Ethernet device
can be positively determined by reading the Vital Product Data (VPD)
Serial EEPROM which provides storage of the MVME5100 hardware
configuration. Refer to Appendix B, MVME5100 VPD Reference
Information for more information on VPD. Refer to the Intel GD82559ER
Reference Manual and Data Sheet, as referenced in Appendix A, Related
Documentation, for additional details on the Ethernet controller.
