7.The Progress tab displays the status of the firmware upgrade. Do not interrupt the procedure. The process begins by erasing flash sectors and then uploading the firmware file.

8.If the process fails, do not use the Start Over button. Close GFirm instead and verify you are using a 9-pin straight-through serial cable and that baud rate and flow control are configured properly. Restart GFirm and return to step one of this procedure.

9.When the upgrade is complete, the Finished tab appears. Check the front panel of unit and verify the proper firmware version for your unit is now displayed. If you have no more units to upgrade, you can now close the GFirm program.

If updating multiple units, move the RS-232 connection to the next unit and click Start Over to continue.

10.After upgrading the firmware on all units, restore expansion bus connections.
