Using a Control Word to Reboot the Module 
If you need to cold boot the module from the processor without using the 
Coldboot mailbox, use the ModuleStatus_SetOperatingMode control word 
variable. 
To reboot the module 
1  Enter the hexadecimal value 16#9999 in the 
ModuleStatus_SetOperatingMode register, as shown in the following 
illustration. 
2  Add the following lines to the program file: 
This logic will reset the value in ModuleStatus_SetOperatingMode to 
16#0000. 
Note: It is normal for the remote (passive) Master in Hot Standby applications to reboot twice 
during this procedure.
