5.To activate the new microcode, it is necessary to swap the operational
microcode with the backup microcode, using the SWAP MICROCODE command and the SWAP FPGA_PICOCODE command. Don′t forget to SAVE
ALL first as the SWAP will reset the subsystem and any unsaved changes will be lost.
Reminder
This must be performed with No operational traffic flowing in through the 8285. Normally this operation would be done during a scheduled maintenance period.
