To perform a firmware upgrade recovery, do the following:
1. Slide the Firmware Upgrade Recovery Switch (see p. 6) to the Recover
position.
2. Power off and restart the switch according to the instructions given in the
Powering Off and Restarting section (p. 18).
3. Slide the Firmware Upgrade Recovery Switch back to the Normal
position.
4. Repeat Step 2.
Note: If one of the child units fails to upgrade successfully, unchain it from the

independently. After it has been successfully upgraded, plug it back into
the chain
independently. After it has been successfully upgraded, plug it back into
the chain
