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.
2.8.7
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 
 an
 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
