Use the undo poe enable command to

By default, the PoE feature on a port is
enabled if the PoE feature is enabled on a board.

Parameter
slot-number:

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:
l
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.
l
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.
l
If you insert a PoE-incapable board into the
slot for which a rated power output is reserved, the reserved power output
shall be released.
l
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.

Description
Use the poe legacy enable slot command
to enable the board to perform PoE-compatibility detection for the remote PDs.
Use the undo poe legacy slot command
to disable PoE-compatibility detection for the remote PDs.
By default, PoE-compatibility detection for
PDs is disabled on the board.
Through the PoE-compatibility detection,
the switch can detect the PDs incompatible with IEEE802.3af and supply power to
them.
Caution:
PoE-compatibility
detection process is very slow and has impact on the system performance, so the
PoE-compatibility detection is not recommended if all PDs connected are
IEEE802.3af-compatible ones.

Parameter
auto:

slot-number:

Description
Use the poe power-management
command to configure the PoE management mode of the switch.
By default, the PoE management mode of the
switch is manual.
This command and the PoE priority settings
of PoE ports will work together to control the power feeding of the switch when
the switch is reaching its full power load in power supply.
l
auto mode: When
the switch is reaching its full load in supplying power, it will first supply
power to the PDs that are connected to the ports with critical priority, and
secondly supply power to the PDs that are connected to the ports with high
priority. For example, port A has the power priority of critical. When
the switch is reaching full load and a new PD is now added to the port A, the
switch will power down a PD that is connected to a port with the lowest
priority and turn to feed this new PD.
l
manual mode: When
the switch is reaching its full load in supplying power externally and a new PD
is added, it will neither take the priority into account nor make change to its
original power supply status; only the information about the newly added device
is provided. For example, port A has the priority of critical. When the
switch is reaching full load and a new PD is now connected to port A, the
switch does not supply power to this new device.

the full mode to update and restore the software.
l
When the upgrade procedure is interrupted for
some unexpected reasons (such as failure which causes restart), if the update
in the full mode fails after restart, you must upgrade the software in
the full mode after power-off and restart of the device, and then
restart the device manually. In this way, the former PoE configuration can be
