CHAPTER 5: Operation
The ServSwitch Wizard’s front-panel 7-segment display should now show a
lowercase “u” to indicate that the Wizard is ready to be upgraded:
5. Run the SSW
xyz
.EXE firmware-upgrade program that you downloaded in
step 1. Follow the directions that appear on the host PC’s screen to transfer
the new firmware to the Wizard. The Wizard’s 7-segment display will change
to show an uppercase “U” and its dot will flash to show that the Wizard’s
receiving data from the PC:
6. When the upgrade’s complete, the 7-segment display will change back to the
lowercase “u” and the dot will stop flashing. Move position 7 of the Wizard’s
DIP switch back to OFF (down) to return the Wizard to normal operation.
CAUTION—if the upgrade goes wrong:
The upgrade program rewrites the Wizard’s existing firmware code with
the code in the SSW
xyz .HEX file. If the upgrade process is interrupted,
the Wizard will contain invalid code and will not operate properly.
A partial, interrupted, or failed upgrade can be fixed, but only if you
immediately repeat the upgrade process without turning OFF position 7
of the Wizard’s DIP switch. (The code that the Wizard uses to download
new firmware is not itself affected by the upgrade process.) If you move
position 7 back to OFF after a failed upgrade attempt, the Wizard will
begin running the incomplete code. This could have unpredictable
results and might damage your Wizard or the attached equipment!
7. Verify that the upgrade has been successful by having the Wizard indicate its
new firmware revision as described in Section 4.2.9 .
