Firmware Upgrade Recovery
There are basically two conditions that call for firmware upgrade recovery:
Š When you invoke Firmware Upgrade Mode (see p. 29), but decide not to
proceed with the upgrade.
Š When the Mainboard firmware upgrade fails.
To perform a firmware upgrade recovery, do the following:
1. Power off the switch.
2. Slide the Firmware Upgrade Recovery Switch (see p. 7) to the Recover
position.
3. Use the Firmware Upgrade Cable (provided with this unit), to connect a
COM port on your computer with the Firmware Upgrade Port on the
switch.
4. Power the switch back on.
5. Follow the upgrade procedures under Starting the Upgrade section.
6. After the upgrade completes successfully, power the switch off, once
again.
7. Slide the Firmware Upgrade Recovery Switch back to the Normal
position.
8. Power the switch back on.
This completes the Firmware Upgrade Recovery operation, and the switch is
ready for use.
