By default, the board does not detect the compatibility of the PD connected to it.
Caution:
Detecting an incompatible device slows down the detection and decreases system
performance; therefore, you are not recommended to enable compatibility detection if
the device connected is 802.3af-compliant.
Examples
# Enable the board in slot 2 to detect the compatibility of the PD connected to it.

H3C S9500 Series Routing Switches Chapter 1 PoE Configuration Commands
1-9
Description
Use the poe mode command to configure the PoE mode on the current port.
Use the undo poe mode command to restore the default PoE mode on current port.
By default, the port adopts signal lines to supply power.
Caution:
H3C S9500 series routing switches currently do not support the spare mode. If a PD
only supports the spare mode, a conversion is needed.
Examples
# Configure the PoE mode on current port to signal.
[H3C-GigabitEthernet3/1/1] poe mode signal
1.1.11 poe power-management
Syntax
poe power-management { auto | manual } slot slot-num
View
System view
Parameters
slot-num: Number of the slot where the board resides.
auto: The switch automatically manages the PoE mode on a board.
manual: You need to manually manage the PoE mode on a board on the switch.
Description
Use the poe power-management command to configure the PoE power management
mode for a board on the switch.
By default, you need to manually manage PoE on the board on the switch.
Before the power supply is almost fully loaded, the system powers all ports. Working
together with the command for configuring PoE priority on a port, this command takes
effect when the external power supply by the switch is almost fully loaded.
The following section describes PoE in auto mode and in manual mode:
Command Manual – PoE
H3C S9500 Series Routing Switches Chapter 1 PoE Configuration Commands
1-10
z Auto mode: Priority management mode. If new PDs are connected to the switch
when the external power supply is almost fully loaded, the switch first powers the
PD connected to the port whose PoE priority is the highest. For example, assume
that the PoE priority on port A is set to critical. If a new PD is connected to port A
when the external power supply by the switch is almost fully loaded, the switch
stops powering the PD connected to the port whose PoE priority is the lowest and
begins to power the PD connected to port A.
z Manual mode: If new PDs are connected to the switch when the external power
supply is almost fully loaded, the switch disregards the PoE priority of the port but
notifies you that a new device is connected, without changing the original PoE
status. For example, assume that the PoE priority on port A is set to critical. If a
new PD is connected to port A when the external power supply by the switch is
fully loaded, the switch notifies you that a new device is connected but will not
power the device connected to port A.
Related command: poe priority.
Examples
# Configure the switch to automatically power the PD connected to the board in slot 2.
[H3C]poe power-management auto slot 2
# Restore the mode in which the switch powers the PD connected to the board in slot 2
to manual.

1.1.13 poe priority
Syntax
poe priority { critical | high | low }
undo poe priority
View
Ethernet port view
Parameters
critical: Sets the port priority to critical (the highest).
high: Sets the port priority to high.
low: Sets the port priority to low.
Description
Use the poe priority command to set the PoE priority on a port.
Use the undo poe priority command to restore the default priority.
By default, the PoE priority on each port is low.
Caution:
When the PoE power of the switch is not enough to support all the port, the switch
supplies power to ports with higher priority, and powers down some ports with lower
priority.
Examples
# Set the PoE priority of current port to critical.
[H3C-GigabitEthernet3/1/1] poe priority critical
# Restore the default priority.
[H3C-GigabitEthernet3/1/1] undo poe priority
