Upgrade Failed
If the Upgrade Succeeded screen doesn’t appear, it means that the upgrade failed to complete
successfully, in which case you should do the following:
1. Power off the CS1782 and remove its housing.
2. Using a jumper cap, short the jumper on the mainboard labeled J17. The diagram below indicates
the jumper location on the CS1782 board:
3. Power on the CS1782. It will now work with the factory default rmware.
4. Do the rmware upgrade procedure again.
5. After the upgrade procedure completes, power off the switch, remove the jumper cap from J17,
close the housing, and power the CS1782 on again.
