2.9.2 10/100Mb Ethernet Interface
The 10/100Mb Ethernet interface (Ethernet 2) comes from the GT-64260B, and connects to an
external PHY. This port can be routed to a front-panel RJ-45 connector or to the P2 connector
with user-configurable jumpers.
Each Ethernet interface is assigned an Ethernet Station Address. The address is unique for each
device. The Ethernet Station Address is displayed on a label affixed to the board. The assembly
policy is to assign MAC addresses in such a manner that the higher value MAC address is
assigned to Ethernet port 1 and the lower to Ethernet port 2.
In addition, the Gigabit Ethernet address is stored in a configuration ROM interfaced to the
82545GM device, while the 10/100Mb Ethernet address is stored in the on-board VPD serial
EEPROM.
2.9.3 PCI-to-PCI Bridges
The MVME5500 uses a PCI 2.1 compliant, 66 MHz capable, HiNT PCI 6154 PCI-to-PCI bridge.
The primary side connects to PCI Bus 0.0 of the GT-64260B and PMC/IPMC slot 1. The
secondary side connects to PCI Bus 0.1 on which a PMC expansion connector and the VME
controller resides.
2.9.4 PMC Sites
The MVME5500 board supports two PMC sites. Both sites support processor PMC boards with
two IDSELs and two arbitration request/grant pairs. Slot 1 is connected to PCI Bus 0.0 of the GT-
64260B and is 66 MHz capable. Slot 2 is connected to PCI Bus 1.0 of the GT-64260B and is also
66 MHz capable.
If a PMC module is plugged into PMC slot 1, the memory mezzanine card cannot be used
because the PMC module covers the memory mezzanine connector.
2.9.5 PCI IDSEL Definition
PCI device configuration registers are accessed by using the IDSEL signal of each PCI agent to
an A/D signal as defined in the Peripheral Component Interconnect (PCI) Local Bus Specification,
Revision 2.2. IDSEL definitions for the MVME5500 are shown in the MVME5500 Single-Board
Computer Programmer’s Reference Guide.
