A11 – 6U VMEbus PowerPC Workstation
The A11 is an industrial PowerPC workstation with scalable performance delivering
up to 1160 MIPS. When equipped with the 603e, the A11 delivers excellent price-
performance for cost-sensitive applications with a need for high computing power.
The board can also be ordered with the 740 PowerPC CPU family for applications
where maximum perfomance is required.
The A11 is a complete state-of-the-art single-board computer needing only one slot
on the VMEbus. It offers fast Ethernet and Ultra2 SCSI controllers, a large amount
of DRAM, Flash and CompactFlash memory. Four serial interfaces are provided -
two of them default as COM3 and COM4, and the others as COM1 and COM2
directly at the front panel or via a transition module.
The A11 offers computer I/O flexibility by providing two slots for PC•MIP
mezzanine modules, while still providing full front-panel connectivity. Both Type I
and Type II PC•MIP modules can be used to equip the A11 with a full range of
workstation and industrial I/O options. Graphics for VGA, additional Ethernet or
SCSI for server or redundancy purposes, fieldbus interfaces for remote I/O control,
and many others are available, depending on the application.
The A11 CPU board is compatible with Motorola's PowerPC computer boards
(MVME1600 and MVME2600) and offers I/O compatibility with many existing P2
transition modules from Motorola (MVME712M) and other vendors.

Electrostatic discharge (ESD) can damage components. To protect the board and
other components against damage from static electricity, you should follow some
precautions whenever you work on your computer.
• Power down and unplug your computer system when working on the inside.
• Hold components by the edges and try not to touch the IC chips, leads, or cir-
cuitry.
• Use a grounded wrist strap before handling computer components.
• Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.
• Store the board only in its original ESD-protected packaging. Retain the original
packaging in case you need to return the board to MEN for repair.

1.2 Configuring the Hardware
You should check your hardware requirements before installing the board in a
system, since most modifications are difficult or even impossible to do when the
board is mounted in an enclosure.
The following check list will give an overview on what you might want to configure.
DRAM SO-DIMM modules
The A11 is shipped with 32MB DRAM on board. You should check on your
main memory needs and install a suitable SO-DIMM module if necessary.
Refer to Chapter 2.5.2 SDRAM on page 23 for a detailed installation
description and hints on supported SO-DIMM modules.
CompactFlash
Refer to Chapter 2.10 CompactFlash on page 37 for a detailed
installation description and hints on supported CompactFlash cards.
PC•MIPs
Refer to Chapter 2.9.1 Installing PC•MIPs on page 35 for a detailed
installation description. Also, observe the installation recommendations
given in the M-Module’s user manual.
Rear I/O adapter
Refer to Chapter 2.21.2.3 Connecting a Rear I/O Adapter to P2 on page
54 for hints on connection of a rear I/O adapter.
PCI Expansion
Refer to Chapter 2.8 PCI Expansion on page 33 for more information on
possible PCI expansion.

1.3 Integrating the Board into a System
The A11 is a complex board and setting it up requires experience. You can use the
following check list when installing the CPU board in a VMEbus system for the first
time and with minimum configuration.
The board is completely trimmed on delivery. Perform the following procedure
without a PC•MIP installed!
Power-down the system.
Remove all boards from the VMEbus system.
Install the A11 in slot 1 of the system.
Connect a terminal to the standard RS232 interface COM1 (9-pin micro D-Sub
connector) by wiring the following lines to the connector:
Table 1. Terminal Lines of the 9-pin micro D-Sub RS232 Plug Connector
(COM1)
Set your terminal to the following protocol:
- 9600 baud data transmission rate
- 8 data bits
- 1 stop bit
- No parity
Note: If you need to restore these default settings on the A11, do the following:
Press the Reset and Abort buttons at once.
Release the Reset button.
Hold the Abort button until the green front-panel LEDs light up in succes-
sion, then release the button.
Press the Reset button again.
Power-up the system.

The terminal displays the following message:
Now you can use the MENMON debugger (see detailed description in Chapter
3 MENMON on page 57).
Observe the installation instructions for the respective software.
1.4 Installing Operating System Software
The A11 supports VxWorks, OS-9, LynxOS and QNX.
You can find any software available on MEN’s website.
By standard, no operating system is installed on the board. Please refer to MEN’s
operating system installation documentation on how to install the software!

Functional Description

2 Functional Description
The following describes the individual functions of the A11 and their configuration
on the board. There is no detailed description of the individual controller chips and
the CPUs. They can be obtained from the data sheets or data books of the
semiconductor manufacturer concerned (Chapter 5.1 Literature and WWW
Resources on page 100).
2.1 Power Supply
The A11 is supplied with +5V via the VMEbus. However, PC•MIPs, PCI expansion
cards or rear I/O adapters may need +12V.
Two power supplies generate different supply voltages on the board: One is used for
the PowerPC core voltage, which is factory-set for the corresponding processor. The
other converter is fixed to 3.3V. It supplies the PC•MIP PCI bus and the host
memory bus devices.
2.2 Clock Supply
The clock supply generates all clocks for the on-board devices (PowerPC, SDRAM,
L2 Cache, host bridge, PCI bus devices). The clock frequency is factory-set for the
corresponding processor.
The local PCI clock is limited to 33MHz because of the Tundra Universe II
VMEbus chip.
