Upgrade Failed
If a device fails to complete the upgrade successfully, start the firmware
upgrade procedure again (see p. 64).
Firmware Upgrade Recovery
If the firmware upgrade procedure is aborted prematurely (due to a power
outage, for example), the switch that was being upgraded at the time may
become inoperable, and may be incapable of accepting a normal firmware
upgrade.
To recover from a failed firmware upgrade:
1. Slide the unit's Firmware Upgrade Recovery Switch (see p. 8), to the
RECOVER position.
2. Perform a system reset (see System Reset Button on p. 7). The switch is
now ready to be upgraded.
3. Slide the Recovery Switch back to the NORMAL position.
4. Start the firmware upgrade procedure again (see p. 64).
