Parameters
slot-number: Number of the slot where the board resides.
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:
zBefore 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.
zAfter 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.
zIf you insert a PoE-incapable board into the slot for which a rated power output is
reserved, the reserved power output shall be released.
zIf 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.

Parameters
slot-number: Number of the slot where the board resides.
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.

Parameters
auto: Manages PoE of the switch automatically.

slot-number: Number of the slot where the board resides.
Description
Use the poe power-management command to configure the PoE management mode
of the switch.

Command Manual – PoE
H3C S7500 Series Ethernet Switches Chapter 1 PoE Configuration Commands
1-13
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.
zauto 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.
zmanual mode: When the switch is reaching its full load in supplying power
externally and a new PD is added, it will neither consider the priority 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.

Use the undo poe priority command to restore the default PoE priority.

Command Manual – PoE
H3C S7500 Series Ethernet Switches Chapter 1 PoE Configuration Commands

and takes effect when the PoE power output of the switch reaches nearly to its
maximum value.

Parameters
refresh: Upgrades the existing valid software in the PSE in the refresh mode.
full: Reloads the software to the PSE when there is no valid software in the PSE.
filename: Upgrade file name, with a length of 1 character to 63 characters.
Description
Use the poe upgrade command to upgrade the processing software in the PSE online.
Note:
zThe full mode is used only when you cannot use the refresh mode.
zWhen the PSE processing software is damaged (that is, no PoE commands can be
successfully executed), you can use the full mode to update and restore the
software.
zWhen 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 restored.
