8 BOOTCODE AND FIRMWARE UPGRADE 8.1INTRODUCTION
This section explains how to upgrade the G650 boot code and firmware.
BEFORE PERFORMING THE UPGRADE PROCEDURE CHECK THAT BOOT AND FIRMWARE VERSION MATCH
The boot code and firmware versions can be seen in the relay main screen: The relay firmware version appears after the
text "G650" (3.74 in the example) with the boot program version (4.10 in the example) followed by "GENERAL ELECTRIC",
the relay model and the default front RS232 port communication parameters.
BOOT CODE RELEASE NOTES
It is mandatory to maintain version compatibility between firmware and boot code in the upgrade procedure, otherwise the
relay will not start after upgrading.
NOTE
A STEP LIST SUMMARY that will allow the user to control the upgrading process is included at the end of this section.
It is necessary to read chapter 8 before accomplishing the G650 UPGRADE PROCEDURE.
Be aware that boot program and firmware upgrades will erase all the data contained in the relay, thus it is advisable to
save all the data, oscillography, events, settings and configuration files previously.
