Memory Clear Debug Procedures
Several memory clear procedures are possible and are listed below. Use of these commands
will clear all information from the CFN III memory. To perform a memory clear, proceed as
follows:

2
Set memory board S2 switch for debug mode.
3
Remove SC3 CPU board K4.

Enter the Dbug Mode as in
“Preparing Before Entering Dbug Mode”
on
. At the
prompt “>> >>---..”
5
Preform any of the procedures below to complete Dbug memory clear.
Note: All data and configuration information will be written over with 0’s.
Procedure 1
“!”(! Equals SHIFT+1) Will test all memory address and set to 0’s. Process takes about
20 minutes. The test will run from A00 to D0F. It is very important to wait until the screen
displays D0F to fully complete the test and clear the memory.
Procedure 2
Enter F 1000,1000000,00 press Enter and then enter F 1000000,1FFFFF,0 press Enter. This
process takes just a few seconds each.
Procedure 3
Enter F 100,FFFFF,0 and press Enter and then enter F 0,100,0 press Enter. This process
takes just a few seconds each. However the second entry causes a reboot as it clears the Dbug
process space.
