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.
