Description
Use the poe enable slot command to enable the PoE feature on a board.
Use the undo poe enable slot command to disable the PoE feature on a board.
By default, the PoE feature is disabled on a board.
Note:
z Before enabling the PoE feature on a board, you must ensure that the remaining
power output is not less than the maximum power required for the board.
Otherwise, PoE cannot be enabled on the board correctly.
z After PoE is enabled on a PoE board, the rated power output shall be reserved for
the slot even when the board is removed from the slot. You need to release this
power output using the undo poe enable slot command.
z If you insert a board which does not support PoE into the slot for which a rated
power output is reserved, the reserved power output shall be released.
z If you insert a PoE board of another type into the slot for which a rated power
output is reserved, the switch still applies the former PoE configuration to the port.
