Motorola CPCI-6020 manual Hardware Installation, Enable Write-Protect for Entire Flash on Bank a

Enable/Disable Lockdown of One or More Flash Blocks for Bank A Hardware Preparation and Installation

When using the +12 V and -12 V power disable (J18 jumper is installed), +12 V and -12 V power is not provided to on-board CPCI-6020 electronics or to the rear transition module. This may affect operation of any modules installed, such as: a PMC on the CPCI-6020 or a PIM or SIM on the rear transition module. For example, COM Port 3 and COM Port 4 on the rear transition module will not operate when the J18 jumper is installed. Generally, this jumper should be installed when there is no +/-12 V power coming from the chassis.

2.8.5Enable/Disable Lockdown of One or More Flash Blocks for Bank A

This 0.1 inch, 2-pin header (J17) located on the CPCI-6020 is used to enable lockdown of one or more flash blocks of bank A. When a jumper is installed between pins 1 and 2, one or more blocks of bank A are locked. Blocks in lockdown cannot be unlocked with the Flash Unlock command.

2.8.6Enable Write-Protect for Entire Flash on Bank A

This 0.1 inch, 2-pin header (J20) located on the CPCI-6020 is used to enable write-protect for the entire flash on bank A. When a jumper is installed between pins 1 and 2, memory contents cannot be altered in the entire flash.

2.8.7Remote Switch

This 0.1 inch, 3-pin header (J19) located on the CPCI-6020 allows you to connect a remote switch that performs the same function as front panel reset and abort switch. The pin configuration is as follows:

Pin #

1

2

3

Signal

Abort

GND

RESET

2.9Hardware Installation

The following sections discuss the installation of a PMC module on the CPCI-6020 baseboard, the installation of CompactFlash, and the installation of the complete CPCI-6020 assembly into a CompactPCI chassis. Also described are the start-up procedure and system considerations relevant to installation. Before installing the CPCI-6020, ensure that the serial ports and all jumpers are properly configured, refer t o CPCI-6020 Baseboard Preparation on page 40 and Preparing the Transition Module on page 131 for serial port configurations.

In most cases, the memory mezzanine card (RAM500) is already in place on the baseboard. The user-configured jumpers are accessible with the mezzanines installed. At least one RAM500 memory mezzanine card must be installed on the CPCI-6020 prior to operation in order for the board to function properly. To install one or more RAM500 memory mezzanine cards, refer to Chapter 6, RAM500 Memory Expansion Module.
