Applying a PoE profile
You can apply a PoE profile in system view or PI view. If you perform the operation in both views, the
most recent operation takes effect. To apply a PoE profile to multiple PIs, perform the operation in
system view. If a PoE profile is applied, it cannot be deleted or modified before you remove its
application.
A PoE profile can be applied to multiple PIs, but a PI can have only one PoE profile.

Upgrading PSE firmware in service
You can upgrade the PSE firmware in service in either of the following modes:
• Refresh mode—Updates the PSE firmware without deleting it. You can use the refresh mode
in most cases.
• Full mode—Deletes the current PSE firmware and reloads a new one. Use the full mode if the
PSE firmware is damaged and you cannot execute any PoE commands.
If the PSE firmware upgrade fails because of interruption such as a device reboot, you can restart the
device and upgrade it in full mode again. After the upgrade, restart the device manually for the new
PSE firmware to take effect.
