Firmware Upgrade Recovery
If the firmware upgrade procedure is unnaturally aborted (due to an outage, for
example), the switch being upgraded may become inoperable and incapable of
accepting a normal firmware upgrade.
If this occurs, to recover, do the following:
1. Power off the CS1732
A / CS1734A and ensure all LEDs are off.
2. Slide the unit’s Firmware Upgrade Switch to the UPGRADE position.
3. Connect the firmware upgrade cable.
4. Power on the CS1732
A / CS1734A.
The CS1732
A / CS1734A is now ready to be upgraded.
5. Start the firmware upgrade procedure again. See Starting the Upgrade,
page 26.
After the upgrade has successfully completed, do the following:
6. Power off the CS1732
A / CS1734A and ensure all LEDs are off.
7. Slide the unit’s Firmware Upgrade Switch to the NORMAL position.
8. Power on the CS1732
A / CS1734A.
