About PoE
Power over Ethernet (PoE) enables a network device to supply power to terminals over twisted pair cables.
PoE system
As shown in Figure 1, a PoE system includes the following elements:
· PoE power supply—A PoE power supply provides power for the entire PoE system.
· PSE—A power sourcing equipment (PSE) supplies power to PDs.
· PI—A power interface (PI) is a PoE-capable Ethernet interface on a PSE.
· PD—A powered device (PD) receives power from a PSE. PDs include IP telephones, APs, portable chargers, POS terminals, and Web cameras. You can also connect a PD to a redundant power source for reliability.
AI-driven PoE
AI-driven PoE innovatively integrates AI technologies into PoE switches and offers the following benefits:
· Adaptive power supply management
AI-driven PoE can adaptively adjust the power supply parameters to fit power needs in various scenarios such as multiple types of PDs and address issues such as no power supply to a PD and power failure, minimizing human intervention.
· Priority-based power management
When the power demanded by PDs exceeds the power that can be supplied by the PoE switch, the system supplies power to PDs based on the PI priorities to ensure power supply to critical businesses and reduce power supply to PIs of lower priorities.
· Smart power module management
For a PoE switch with a dual power module architecture, AI-driven PoE can automatically calculate and regulate power output of each power module based on the type and quantity of the power modules, maximizing the power usage of each power module. When a power module is removed, AI-driven PoE recalculates to preferentially guarantee power supply to PDs that are being powered.
· Alarms and logs
AI-driven PoE constantly monitors the PoE power supply status. If an exception occurs, it automatically analyzes, recovers, or even resets the PoE function, and outputs alarms and logs for reference.
· High PoE security
When an exception such as short circuit or circuit break occurs, AI-driven PoE immediately starts self-protection to protect the PoE switch from being damaged or burned.
· Fast reboot
Immediately when the PoE switch restarts upon a power failure, AI-driven PoE starts to supply power to PDs before the PoE switch completes startup, shortening the PD recovery time from a power failure.
· Perpetual PoE
During a hot reboot of the PoE switch from the reboot command, AI-driven PoE continuously monitors the PD states and ensures continued power supply to PDs, maintaining terminal service stability.
· Remote PoE
AI-driven PoE adaptively adjusts the network bandwidth based on the transmission distance between a PSE and PD. When the transmission distance exceeds 100 m (328.08 ft), the system automatically decreases the port rate to reduce the line loss and ensure the signal and power transmission quality. With AI-driven PoE enabled, a PSE can transmit power to a PD of 200 to 250 m (656.17 to 820.21 ft) away.
Protocols and standards
802.3af, 802.3at, and 802.3bt are the 3rd, 4th, and 5th editions of the PoE protocol established by the IEEE. The differences between the three PoE technologies lie in their power transmission capabilities and the number of wires used for power transmission.
· 802.3af, also known as the PoE standard, was released in 2003. It provides a maximum power output of 15.4 W and uses 2 pairs of wires for power transmission.
The name of the 802.3af standard is 802.3af-2003, IEEE Standard for Information Technology - Telecommunications and Information Exchange Between Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 3: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications - Data Terminal Equipment (DTE) Power Via Media Dependent Interface (MDI).
· 802.3at, also known as the PoE+ standard, was released in 2009. It provides a maximum power output of 30 W and uses 2 or 4 pairs of wires for power transmission. It is backward compatible with the 802.3af standard.
The name of the 802.3at standard is 802.3at-2009, IEEE Standard for Information technology-- Local and metropolitan area networks-- Specific requirements-- Part 3: CSMA/CD Access Method and Physical Layer Specifications Amendment 3: Data Terminal Equipment (DTE) Power via the Media Dependent Interface (MDI) Enhancements.
· 802.3bt, also known as the PoE++ standard, was released in 2018. It provides a maximum power output of 90 W and is compatible with existing low-power PoE devices. This standard uses 4 pairs of wires for power transmission and supports PoE devices over long distances and with better performance. It is backward compatible with the 802.3af and 802.3at standards.
· The name of the 802.3bt standard is 802.3bt-2018 - IEEE Standard for Ethernet Amendment 2: Physical Layer and Management Parameters for Power over Ethernet over 4 pairs.
Restrictions: Hardware compatibility with PoE
Only the PoE models in the S5580X-HI switch series supports PoE.
Restrictions and guidelines: PoE configuration
You can configure a PI through either of the following ways:
· Configure the settings directly on the PI.
· Configure a PoE profile and apply it to the PI. If you apply a PoE profile to multiple PIs, these PIs have the same PoE features. If you connect a PD to another PI, you can apply the PoE profile of the original PI to the new PI. This method relieves the task of configuring PoE on the new PI.
You can only use one way to configure a parameter for a PI. To use the other way to reconfigure a parameter, you must first remove the original configuration.
You must use the same configuration method for the poe max-power max-power and poe priority { critical | high | low } commands.

Before you configure PoE, make sure the PoE power supply and PSEs are operating correctly.
Enabling PoE
Enabling PoE for a PI
About this task
After you enable PoE for a PI, the system reserves and supplies power to the PD connected to the PI.
If the PI will result in PSE power overload, the following restrictions apply:
· If the PoE priority policy is not enabled on the PI, the PI cannot supply power to the connected PDs.
· If the PoE priority policy is enabled on the PI, whether the PDs can be powered depends on the priority of the PI.
For more information about the PI priority policy, see "Configuring the PI priority policy."
Power can be transmitted over a twisted pair cable in either of the following modes:
· Signal pair mode—Signal pairs 1, 2, 3, and 6 of the twisted pair cable are used for power transmission.
· Spare pair mode—Spare pairs 4, 5, 7, and 8 of the twisted pair cable are used for power transmission.
Restrictions and guidelines
The device supports power transmission only over signal wires.
A PSE can supply power to a PD only when the PSE and PD use the same power transmission mode. If the PSE and PD use different power transmission modes, you must change the order of the lines in the twisted pair cable to supply power to the PD.
When you specify a PoE standard for a PI, follow these restrictions and guidelines:
· For your configuration to take effect, restore the PI maximum power to the default before you configure this feature.
· This feature is mutually exclusive with the power class detection mode configuration (poe class-detect).
· IEEE PoE standards are not forward compatible. For a PI to supply power to PDs, make sure the PoE standard version of the PDs is the same as or earlier than the PoE standard version of the PI.
· If a PI operates in IEEE 802.3bt mode and supplies more than 30 W power, changing the PoE standard for the PI will cause the connected PDs to be power cycled. Be cautious when you modify the configuration of this feature.

poe power-delay time
By default, PoE delay is disabled.
Disabling PoE on shutdown interfaces
About this task
By default, the device continues supplying power to an interface after the interface is shut down by the shutdown command or by an upper layer module such as monitor link. As a result, the PD connected to the shutdown interface operates continuously but fails to access the network.
This task disables the PoE module from supplying power to an interface after the interface is shut down. After the interface comes up or you disable this task, the PoE module resumes power supply to the interface.
Restrictions and guidelines
The task does not power off an interface that has been shut down but is supplying power to a PD.
Procedure
1. Enter system view.
system-view
2. Disable PoE on shutdown interfaces.
poe track-shutdown
By default, PoE is not disabled on shutdown interfaces.
Allowing inrush currents from PDs
About this task
Inrush current might occur at PD startup and trigger PSE self-protection, As a result, the PSE stops supplying power to the PDs. To continue power supply to the PDs, configure this feature to allow inrush currents drawn by PDs.
IEEE 802.3af and IEEE 802.3at define specifications for inrush current. Support for the specifications defined by IEEE 802.3af and/or IEEE 802.3at depends on the device model.

Configuring the PoE priority policy
Configuring the PI priority policy
About this task
The PI priority policy enables the PSE to perform priority-based power allocation to PIs when PSE power overload occurs. The priority levels for PIs are critical, high, and low in descending order.
When PSE power overload occurs, the PSE supplies power to PDs as follows:
· If the PI priority policy is disabled, the PSE supplies power to PDs depending on whether you have configured the maximum PSE power.
¡ If you have configured the maximum PSE power, the PSE does not supply power to the newly-added or existing PD that causes PSE power overload.
¡ If you have not configured the maximum PSE power, the PoE self-protection mechanism is triggered. The PSE stops supplying power to all PDs.
· If the PI priority policy is enabled, the PSE supplies power to PDs as follows:
¡ If a PD being powered causes PSE power overload, the PSE stops supplying power to the PD.
¡ If a newly-added PD causes PSE power overload, the PSE supplies power to PDs in priority descending order of the PIs to which they are connected. If the newly-added PD and a PD being powered have the same priority, the PD being powered takes precedence. If multiple PIs being powered have the same priority, the PIs with smaller IDs takes precedence.
Restrictions and guidelines
Before you configure a PI with critical priority, make sure the remaining power from the maximum PSE power minus the maximum powers of the existing PIs with critical priority is greater than maximum power of the PI.
Configuration for a PI whose power is preempted remains unchanged.
Procedure
1. Enter system view.

Configuring PoE monitoring
Configuring PSE power monitoring
About this task
The system monitors PSE power utilization and sends notification messages when PSE power utilization exceeds or drops below the threshold. If PSE power utilization crosses the threshold multiple times in succession, the system sends notification messages only for the first crossing. For more information about the notification message, see "Configuring SNMP."
Procedure
1. Enter system view.
system-view
2. Configure a power alarm threshold for a PSE.
poe utilization-threshold value pse pse-id
By default, the power alarm threshold for a PSE is 80%.
Associating Track with PoE
About this task
The PoE module can collaborate with the Track module to monitor the link status between the device and the PD connected to a PI. For example, if the PD supports the NQA ICMP echo test, you can specify a track entry associated with NQA for the PI to test the reachability of the PD. The NQA ICMP echo test must be configured on a Layer 3 interface. If the PI is a Layer 2 interface, create a VLAN interace and assign the PI to the VLAN interface, or configure the Layer 2 PI to operate in Layer 3 mode.
The Track module notifies the PoE module of the following monitoring results:
· Positive—The monitored object is reachable.
· Negative—The monitored object is unreachable.
· NotReady—The monitoring result is not ready because of reasons such as nonexistence of the NQA group associated with the track entry.
When the Track module detects failure of the link, it changes the track entry state from Positive to Negative, which triggers the PoE module to take the following actions:
· alarm: Outputs an SNMP notification and log.
· alarm-reboot-pd: Outputs an SNMP notification and log and reboots the PD connected to the PI.
For information about SNMP notifications, see "Configuring SNMP."
For information about logs, see "Configuring the information center."
For information about the Track module, see track configuration in High Availability Configuration Guide.
Procedure

Troubleshooting PoE
Failure to set the priority of a PI to critical
Symptom
Power supply priority configuration for a PI failed.
Solution
To resolve the issue:
1. Identify whether the remaining guaranteed power of the PSE is lower than the maximum power of the PI. If it is, increase the maximum PSE power or reduce the maximum power of the PI.
2. Identify whether the priority has been configured through other methods. If the priority has been configured, remove the configuration.
3. If the issue persists, contact H3C Support.
Failure to apply a PoE profile to a PI
Symptom
PoE profile application for a PI failed.
Solution
To resolve the issue:
1. Identify whether some settings in the PoE profile have been configured. If they have been configured, remove the configuration.
2. Identify whether the settings in the PoE profile meet the requirements of the PI. If they do not, modify the settings in the PoE profile.
3. Identify whether another PoE profile is already applied to the PI. If it is, remove the application.
4. If the issue persists, contact H3C Support.
