Enable/Disable Lockdown of One or More Flash Blocks for Bank A
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
Preparing the Transition Module on page 131
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
