Unpacking Instructions

Note If the shipping carton is damaged upon receipt, request that

the carrier’s agent be present during the unpacking and inspection of the equipment.

Unpack the equipment from the shipping carton. Refer to the packing list and verify that al l items are present . Sa ve t he packing material for storing and reshipping of equipment.

Getting Started

Caution

Avoid touching areas of integrated circuitry; static discharge can damage circuits.

ESD Precautions

Motorola strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading a system. Electronic components, such as di sk driv es, comput er boar ds, and memory mod ules, c an be extremely sensitive to ESD. After removing the component from the system or its protective wrapper, 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 unpainted metal part of the system chassis.

Inserting or removing modules with power applied may result in damage

Hardware Preparation and Installation

Preparation

This section discusses certain hardware and software tasks that may need to be performed prior to installing the board in a CompactPCI chassis.

Hardware Configuration

To produce the desired configuration and ensure proper operation of the MCPN750A, you may need to carry out certain hardware modifications before installing the module.

The MCPN750A provides software control over most options by setting bits in control registers after installing the module in a system. You can

also modify the board’s configuration by modifying similar control registers. The MCPN750A control registers are described in the

MCPN750A CompactPCI Single Board Computer Programmer’s Reference Guide (MCPN750A/ PG), whi ch can be accessed on line i n pd f

or html format through the Moto rola Comput er Group Liter ature web site

(http://www.motorola.c om/comp uter/li tera ture).

Some options, however, are not software-programmable. These options are controlled by installing or removing header jumpers or interface modules on the baseboard or the associated transition module.

MCPN750A Baseboard Preparation

Figure 1-2 illustrates the placement of the switches, jumper headers, connectors, and LED indicat ors on the MCPN750A. Manua lly configured items on the baseboard include:

❏ Flash bank selection (J7) ❏ Stand-Alone Operating Mode (J8)

For a discussion of the configu red ite ms on th e trans itio n module , re fer in this chapter to the sections titled TMCPN710 Transition Module Preparation, or to the respec tive user’s manual s for the transit ion modules (listed in the Related Documentation appendix) as necessary.

1-6 Computer Group Literature Center Web Site

The MCPN750A is factory tested and shipped with the configurations

described in the following sections. The MCPN750A’s required and factory-installed debug monitor, PPCBug, operates with those factory settings.

Flash Bank Selection (J7)

The MCPN750A baseboard has provision for 1MB of 16-bit Flash memory and 4MB of linear Flash memory.

The Flash memory is organized in two banks, Bank A is 64 bits wide and Bank B is 16 bits wide. Bank B contains the onboard debugger, PPCBug.

To enable Flash Bank A, place a j umper acr oss he ader J 7 pins 1 and 2. T o enable Fla sh Bank B (1MB of firmware located in sockets on the baseboard), place a jumper across header J7 pins 2 and 3.

Stand-Alone Operating Mode (J8)

The MCPN750A has a stand-alone operating mode that allows the MCPN750A to function withou t t he clock from the sys tem sl ot con tr oll er board. Installi ng a jumper across p ins 1 and 2 of J8 enab les the stan d-alone mode. The J8 jumper must be removed for normal operation.

Hardware Preparation and Installation

System Considerations

The MCPN750A is designed to operat e as a CompactPCI no n-system sl ot board. Consequently, the MCPN750A must be installed in the subrack system slot marked with the circle symbol.

The MCPN750A can operate properly, with or without a system slot controller board. In the standard operating mode (with a system slot board), the system slot board is used to provide clock and arbitration signals to the MCPN750A. In t he sta nd-alo ne mode, a j umper mu st be se t on the MCPN750A, in order to obtain clock signals from other on-board devices.

Installing a jumper on J8 ro utes an onboard PCI clock to the 21554 pri mary side clock input. This allows the MCPN750A to operate in a chassis without a system sl ot c ont roller board instal led. The chassis must pr ovi de +5V, +3.3V, +12V, -12V and VIO to the MCPN750A, and the BD_SEL pin (P1-D15) in the chassis must be grounded. In addition, in the standalone mode, the MCPN750A cannot communicate over the CompactPCI backplane.

On the MCPN750A baseboard, the standard serial console port (

COM1)

serves as the PPCBug debugg er console port. The fir mware console should be set up as follows:

❏ Eight bits per character ❏ One stop bit per character ❏ Parity disabled (no parity) ❏ Baud rate of 9600 baud

9600 baud is the power-up defaul t for serial p orts o n MCP N750A board s. After power-up you can reconfigure the baud rate if you wish, using the PPCBug PF (Port Format) command via the command line interface.

Whatever the baud rate, some type of hardware handshaking — either XON/OFF or via the RTS/CTS line — is desirable if the system supports it.
