Upgrade Failed
If the Upgrade Succeeded screen does not appear, it means that the upgrade failed to complete
successfully, in which case you should do the following:
1. Power off the GCS1204 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 GCS1204 board:
3. Power on the GCS1204. It will now work with the factory default rmware.
4. Repeat the rmware upgrade procedure.
5. After the upgrade procedure completes, power off the switch, remove the jumper cap from J17, close
the housing, and power the GCS1204 on again.
