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.

Enable/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.
2.8.6
Enable 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.

Remote 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:

Hardware 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
