Firmware Upgrade Recovery
Should the switch's main firmware upgrade procedure fail, and the switch
becomes unusable, the following firmware upgrade recovery procedure will
resolve the problem:
1. Power off the switch.
2. Press and hold the Reset Switch in (see Reset Switch, page 9).
3. While holding the Reset Switch in, power the switch back on.
This causes the switch to use the original factory installed main firmware
version. Once the switch is operational, you can try upgrading the main
firmware again.
