1.2 Introduction

The MVME5500 is a single-board computer based on the PowerPC MPC7457 processor and 

the Marvell GT-64260B host bridge with a dual PCI interface and memory controller. On-board 

payload includes two PMC slots, two SDRAM banks, an expansion connector for two additional 

banks of SDRAM, 8MB boot Flash ROM, one 10/100/1000 Ethernet port, one 10/100 Ethernet 

port, 32MB expansion Flash ROM, two serial ports, NVRAM and a real-time clock.

The MVME5500 interfaces to a VMEbus system via its P1 and P2 connectors and contains two 

IEEE 1386.1 PCI mezzanine card (PMC) slots. The PMC slots are 64-bit and support both front 

and rear I/O.

Additionally, the MVME5500 is user-configurable by setting on-board jumpers. Two I/O modes 

are possible: PMC mode or SBC mode (also called 761 or IPMC mode). The SBC mode uses 

the IPMC712 I/O PMC and the MVME712M transition module, or the IPMC761 I/O PMC and 

the MVME761 transition module. The SBC mode is backwards compatible with the MVME761 

transition module and the P2 adapter card (excluding PMC I/O routing) used on the MVME5100 

product. This mode is accomplished by configuring the on-board jumpers and by attaching an 

IPMC761 PMC in PMC slot 1. Secondary Ethernet is configured to the rear.

PMC mode is backwards compatible with the MVME5100 and is accomplished by configuring 

the on-board jumpers.

1.3 Getting Started

This section provides an overview of the steps necessary to install and power up the 

MVME5500 and a brief section on unpacking and ESD precautions.

1.4 Overview of Startup Procedures

The following table lists the things you will need to do before you can use this board and tells 

where to find the information you need to perform each step. Be sure to read this entire chapter, 

including all Caution and Warning notes, before you begin.

1.5 Unpacking Guidelines

Unpack the equipment from the shipping carton. Refer to the packing list and verify that all items 

are present. Save the packing material for storing and reshipping of equipment.

If the shipping carton is damaged upon receipt, request that the carrier’s agent be present 

during the unpacking and inspection of the equipment.

Table 1-1 Startup Overview

ESD

Emerson strongly recommends that you use an antistatic wrist strap and a 

conductive foam pad when installing or upgrading a system. Electronic components, 

such as disk drives, computer boards, and memory modules can be extremely 

sensitive to electrostatic discharge (ESD). After removing the component from its 

protective wrapper or from the system, place the component flat on a grounded, 

static-free surface (and, in the case of a board, component side up). Do not slide the 

component over any surface.

If an ESD station is not available, you can avoid damage resulting from ESD by 

wearing an antistatic wrist strap (available at electronics stores) that is attached to an 

active electrical ground. Note that a system chassis may not be grounded if it is 

unplugged.

Personal Injury or Death

Dangerous voltages, capable of causing death, are present in this equipment. 

Use extreme caution when handling, testing, and adjusting.

Configuring the Hardware

This section discusses certain hardware and software tasks that may need to be performed 

prior to installing the board in a chassis.

To produce the desired configuration and ensure proper operation of the MVME5500, you may 

need to carry out certain hardware modifications before installing the module.

Most options on the MVME5500 are software configurable. Configuration changes are made 

by setting bits in control registers after the board is installed in a system.

Jumpers and switches are used to control those options that are not software configurable. 

These settings are described further on in this section. If you are resetting the board jumpers 

or switches from their default settings, it is important to verify that all settings are reset properly. 

 Configuring the Board

Figure 1-1 illustrates the placement of the jumpers, headers, switches, connectors, and various 

other components on the MVME5500. There are several manually configurable headers and 

switches on the MVME5500 and their settings are shown in Table 1-2. Each default setting is
