CP390 Introduction

1. Introduction

1.1 Overview

PMC modules are renowned for their flexibility and versatility of use. They afford the
user wide ranging system independent solutions by means of easily interchanged or
upgraded mezzanine add-on modules. The PEP CP390 has been designed to maxi­mize the advantages provided by PMC modules in a 3U environment. Flexibility, versa­tility, convenience and ease of use have been keynotes throughout the design process.
The result is a board which, although essentially a carrier for PMC modules, also
includes a wide range of important features such as a PCI-PCI bridge and (optionally
available) the ability to hotswap. Use of the hotswap version means, of course, that all
PMC modules employed on the board are effectively hotswapable.

The CP390 is a 3U non-intelligent, active CPCI carrier board with one PMC slot.

Some of the Outstanding Features of the CP390:

• active carrier with PCI-to-PCI bridge: the primary and secondary PCI busses are
capable of being operated independently of one another

• 32 Bit / 33MHz PCI Bus on the CPCI and on the PMC side

• it supports the Interrupts INTA, INTB, INTC and INTD

• software transparent: the non-hotswap version does not require a software driver.

• it supports all the signals of the PCI Bus on its connectors Jn1 (CON2),
Jn2 (CON3)

• The connectors which connect the mezzanine board with the carrier include all the
signals of a 33MHz, 32-bit, multi-master PCI bus, the power rails for 5V, 3.3V,
V(I/O) and other specialised signals for Board Detection.

• A PCI-to-PCI bridge provides for coupling of the PMC side to the CompactPCI
side, so that two independent PCI busses exist. The PCI-to-PCI bridge is the
INTEL 21150. It is software transparent and consequently a software driver is not
required to manage data transfer between the PMC module and the CPCI bus.

• The CP390 has been designed to function with all PEP CompactPCI backplanes.

Features of the PEP Modular Computers’ PMC modules

PEP Modular Computers’ PMC modules are operable in both CompactPCI and VME
systems. They offer all the key benefits of PC I/O technology, namely:

• low cost solutions

• high performance

• a processor independent local I/O bus

• a broad range of I/O peripheral devices

PEP Modular Computers’ PMC modules may be installed on a variety of different carrier
boards, including:

• CompactPCI 3U/6U: CPU CP600, CP602, CP610, CP611, CP612

• CompactPCI PMC carrier boards such as the CP390 and CP690

Customers who additionally require the functionality of the CP390 in the 6U Form
Factor are referred to PEP’s new double-height PMC Module carrier board, the
CP690, which holds two PMC modules.

CP390 Introduction

1.2 Board Interfaces

CompactPCI Interface

The CompactPCI interface connector J1 (CON1) provides all the necessary signals for
data transfer as defined by PCI Specification Rev. 2.1.

The CP390 is routed to the CompactPCI backplane by means of the Intel 21150 PCI-to­PCI bridge which interfaces the board with a data path width of 32-bit and a speed up to
33MHz.

PMC Interface

The PMC interface of the CP390 provides an easy way to extend a CompactPCI system
via the wide array of interfaces and functions which are available on PMC modules pro­duced by the entire range of PMC vendors. The secondary side of the PCI-to-PCI
Bridge provides a 32-bit wide PCI data path with a speed of up to 33MHz which is
routed to the onboard connectors Jn1 and Jn2. These connectors also provide the
power supply for the PMC module. The interface has been designed to comply with the
IEEE 1386.1 specification which defines a PCI electrical interface for the CMC (Com­mon Mezzanine Card) form factor.

Additionally, the CP390-HS (Hotswap version) has been designed to comply with the
CPCI Hotswap specification PICMG 2.1 R1.0, which means that the power supply of the
PMC modules will be ramped up and a reset generated whenever the board is plugged
into a running system.

2.1 Board Installation

Caution!

If you are using the non-hotswap version of the CP390, please
switch off the target system before installing the board in a free
slot. Failure to do so could endanger your life/health and may
damage your board or system.

ESD Equipment!

Your carrier board and PMC module contain electrostatically sen­sitive devices. Please observe the necessary precautions to avoid
damage to your board:

• Discharge your clothing before touching the assembly. Tools
must be discharged before use.

• Do not touch components, connector-pins or traces.

• If working at an anti-static workbench with professional dis­charging equipment, please do not omit to use it.

PMC Module Installation

1. Place the EMC gasket on the bezel of your PMC-Module

2. Unscrew the stand-off, which is positioned at the PCI-Bridge

Note:

In order to support an active PMC carrier and, therefore, to
comply with the CPCI specification, it was necessary to
place the PCI-to-PCI bridge in the position where a socket
for mounting a stand-off would normally be (PMC specifica­tion). As a result, the second stand-off has been omitted.

3. Push the PMC bezel into the window of the front-panel of the CP390 and plug the
connectors together.

4. Use three screws (M2.5 x 6mm) to fix the board

CP390 Hotswap

4. Hotswap

4.1 Technical Background of CompactPCI Hotswap

In many modern application systems downtime is costly and/or unacceptable. Server
applications, telecommunications networks and automated systems requiring continu­ous monitoring call for a system design in which a single card can be inserted or
extracted without affecting the rest of the system. The ease with which a board may be
removed and replaced is dependent on the mechanical design (form factor), the possi­bility of deactivating the software drivers for the board (operating system) and the ability
to remove and insert the board without disturbing the signal quality on the bus.

CompactPCI hotswap is currently the most effective way to meet this need. Staggered
pins on the backplane guarantee controlled power sequencing of the board, while the
signals ENUM, BDSEL, HEALTHY and the hotswap control and status register bits may
be used to control board access from the software side.

4.1.1 Hotswap System

A hotswap system consists of a hotswap platform which comprises a hotswap back­plane, the system host (CPU) with hotswap features, cooling, power supplies etc. plus
the boards to be hotswapped. Hotswapping is not possible unless the operating system
has the capability to enable and disable the board specific driver during normal opera­tion.

Some special signals (e.g. ENUM, HEALTHY, BDSEL...) have par­ticular routing requirements.

4.1.1.2 The System Host (System Controller)

The System Controller must have the possibility to utilize the special signals defined by
the CompactPCI hotswap specification. If a high availability system is used it must addi­tionally be able to control the hardware connection with the peripheral boards (Hardware
Connection Control).

4.1.1.3 The Hotswap Board

To ensure that a board may be removed and replaced in a working bus without
disturbing the system it requires the following additional features.

• precharge

• power ramping

• hotswap Control and status register bits

• automatic interrupt generation whenever a board is about to be removed or
replaced.

• an LED to indicate that the board may be safely removed.

4.1.1.4 Software and Operating System

No hotswap support is currently provided by Intel based operating systems. Windows
2000, which is scheduled to become available in February 2000, is expected to provide
hotswap support. Special software will require to be developed for other proprietary
systems.

In a hotswap environment the software driver and the operating system have the
following additional requirements:

• The OS must provide the possibility to initialize PCI devices during normal
operation whenever required (allocate resources).

• The OS must provide the possibility to load or unload software drivers during
normal operation whenever required.

4.2 Design Implementation on the CP390

4.2.1 Power Ramping

On the CP390, a special hotswap controller is used to ramp up the supply voltage of the
PMC modules (Back End Power). This is done to avoid transients on the 3.3V and the
5V power supplies from the Hotswap system. When the power supply is stable, the
hotswap controller generates a reset on the PMC slots to put the devices into a definite
state.

4.2.2 Precharge

Precharge is provided on the CP390 by a resistor on each signal line (PCI bus),
connected to a 1V reference voltage.

4.2.3 Handle Switch

A microswitch is situated in the extractor handle. Opening the handle initiates the
generation of the ENUM interrupt (produced by the onboard logic).

!

4.2.4 ENUM# Interrupt

The onboard logic generates a low active interrupt signal to indicate that the board is
about to be extracted from the system or inserted into the system.

4.2.5 Hotswap Control and Status Register / Statemachine

All hotswap peripheral boards provide a HotSwap Control And Status Register which
provides information on the current state of the board. The defined bits in this register
set are named:

Table 4-1: Hotswap Control and Status Register / Statemachine

Bit Name Function

EXT Indication of extraction process
INS Indication of insertion process
LOO Led on
EIM ENUM mask bit

Due to the fact that no 64-bit transparent PCI-to-PCI bridge currently exists, which
would provide built-in hotswap status registers, another way of implementing these bits
had to be found.

The solution, therefore, is to put this information into the onboard logic.
Since on-chip registers handle read and write accesses in the same way, it is necessary

to exercise care when configuring the PCI-to-PCI GPIOs (general purpose IOs).

Attention!
