Motorola MVME5100 manual P2 Input/Output I/O Modes, Input/Output Interfaces, Ethernet Interface

Features Descriptions

P2 Input/Output (I/O) Modes

The MVME5100 has two P2 I/O modes (SBC and PMC) that are user- configurable with jumpers on the board (J6 and J20). The jumpers route the on-board Ethernet port 2 to row C of the P2 connector. Ethernet jumpers (J4, J10, and J17) should also be configured.

The SBC mode (also called 761 or IPMC mode) are backwards compatible	4
with the corresponding MVME712 and MVME761 transition cards and
the P2 adapter card (excluding PMC I/O routing) used on the
MVME2600/2700. The SBC mode is accomplished by configuring the on-
board jumpers and attaching an IPMC712 or IPMC761 PMC in PMC slot
1 of the MVME5100.
PMC mode is backwards compatible with the MVME2300/MVME2400.
PMC mode is accomplished by simply configuring the on-board jumpers.
Note Refer to Chapter 5, Pin Assignments for P2 Input/Output Mode
jumper settings.
Input/Output Interfaces
The following subsections describe the major I/O interfaces on the
MVME5100 including Ethernet, VMEbus, asynchronous communications
ports, real-time clock/NVRAM/Watchdog Timer, other timer interfaces,
interrupt routing capabilities and IDSEL routing capabilities.
Ethernet Interface
The MVME5100 incorporates dual Ethernet interfaces (Port 1 and Port 2)
via two Fast Ethernet PCI controller chips.
The Port 1 10BaseT/100BaseTX interface is routed to the front panel. The
Port 2 Ethernet interface is routed to either the front panel or the P2
connector as configured by jumpers. The front panel connectors are of the
RJ45 type.
