Upgrading the PoE Controller
To upgrade the PoE controller firmware on a port extender, use the following command. You can upgrade the PoE controller firmware
using the firmware packaged with the Dell Networking OS. After the upgrade is successful, the port extender reloads automatically.

take a few minutes to complete. Also, the CLI is blocked until the upgrade is complete.
