CHAPTER 5: Operation
The Multi-Head ServSwitch’s front-panel 7-segment display should now show a
lowercase “u” to indicate that the Switch is ready to be upgraded:
5. Run the SSWxyz.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 Switch. The Switch’s 7-segment display will change to
show an uppercase “U” and its dot will flash to show that the Switch’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 Switch’s
DIP switch back to OFF (down) to return the Switch to normal operation.
CAUTION—if the upgrade goes wrong:
The upgrade program rewrites the Switch’s existing firmware code with
the code in the SSWxyz.HEX file. If the upgrade process is interrupted,
the Switch 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 Switch’s DIP switch. (The code that the Switch 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 Switch will
begin running the incomplete code. This could have unpredictable
results and might damage your Switch or the attached equipment!
7. Verify that the upgrade has been successful by having the Switch indicate its
new firmware revision as described in Section 4.2.8.
