PoE Configuration Example
The newly added function is upgrading the PoE module of the fabric switch remotely. See Upgrading the PSE Processing Software of Fabric Switches Online for details.
PoE Overview Introduction to PoE Power over Ethernet (PoE)-enabled devices use twisted pairs through electrical ports to supply power to the remote powered devices (PD) in the network and implement power supply and data transmission simultaneously.
Advantages of PoE z
Reliability: The centralized power supply provides backup convenience, unified management, and safety.
z
Easy connection: Network terminals only require an Ethernet cable, but no external power supply.
z
Standard: PoE conforms to the 802.3af standard and uses a globally uniform power interfaces;
z
Bright application prospect: PoE can be applied to IP phones, wireless access points (APs), chargers for portable devices, card readers, network cameras, and data collection system.
PoE components PoE consists of three components: power sourcing equipment (PSE), PD, and power interface (PI). z
PSE: PSE is comprised of the power and the PSE functional module. It can implement PD detection, PD power information collection, PoE, power supply monitoring, and power-off for devices.
z
PD: PDs receive power from the PSE. PDs include standard PDs and nonstandard PDs. Standard PDs conform to the 802.3af standard, including IP phones, Wireless APs, network cameras and so on.
z
PI: PIs are RJ45 interfaces which connect PSE/PDs to network cables.
PoE Features Supported by S3600 PoE-enabled S3600 series Ethernet switches include: 1-1

S3600-28P-PWR-SI
z
S3600-28P-PWR-EI
z
S3600-52P-PWR-SI
z
S3600-52P-PWR-EI
A PoE-enabled S3600 switch has the following features: z
As the PSE, it supports the IEEE802.3af standard. It can also supply power to the PDs that do not support the 802.3af standard.
z
It can deliver data and current simultaneously through data wires (1,2,3,and 6) of category-3/5 twisted pairs.
z
Through the fixed 24/48 Ethernet electrical ports, it can supply power to up to 24/48 remote Ethernet switches with a maximum distance of 100 m (328 feet).
z
Each Ethernet electrical port can supply at most a power of 15,400 mW to a PD.
z
When AC power input is adopted for the switch, the maximum total power that can be provided is 300 W. The switch can determine whether to supply power to the next remote PD it detects depending on its available power.
z
When DC power input is adopted for the switch, it is capable of supplying full power to all of the 24/48 ports, that is, 15,400 mW for each port, and the total power is 369.6 W/739.2 W.
z
The PSE processing software on the switch can be upgraded online.
z
The switch provides statistics about power supplying on each port and the whole equipment, which you can query through the display command.
z
The switch provides two modes (auto and manual) to manage the power feeding to ports in the case of PSE power overload.
z
The switch provides over-temperature protection mechanism. Using this mechanism, the switch disables the PoE feature on all ports when its internal temperature exceeds 65°C (149°F) for self-protection, and restores the PoE feature on all its ports when the temperature drops below 60°C (140°F).
z
The switch supports the PoE profile feature, that is, different PoE policies can be set for different user groups. These PoE policies are each saved in the corresponding PoE profile and applied to ports of the user groups.
z
When you use the PoE-enabled S3600 switch to supply power, the PDs need no external power supply.
z
If a remote PD has an external power supply, the PoE-enabled S3600 switch and the external power supply will backup each other for the PD.
z
Only the 100 Mbps Ethernet electrical ports of the PoE-enabled S3600 switch support the PoE feature.

By default, the PoE function on a port is enabled by the default configuration file (config.def) when the device is delivered.
z
If you delete the default configuration file without specifying another one, the PoE function on a port will be disabled after you restart the device.
Setting the Maximum Output Power on a Port The maximum power that can be supplied by each Ethernet electrical port of a PoE-enabled S3600 switch to its PD is 15,400 mW. In practice, you can set the maximum power on a port depending on the actual power of the PD, in the range of 1,000 to 15,400 mW and in the granularity of 100 mW.

Remarks Required 15,400 mW by default.
Setting PoE Management Mode and PoE Priority of a Port When a switch is close to its full load in supplying power, you can adjust the power supply of the switch through the cooperation of the PoE management mode and the port PoE priority settings. S3600 series switches support two PoE management modes, auto and manual. The auto mode is adopted by default. z
auto: When the switch is close to its full load in supplying power, it will first supply power to the PDs that are connected to the ports with critical priority, and then supply power to the PDs that are connected to the ports with high priority. For example: Port A has the priority of critical. When the switch PoE is close to its full load and a new PD is now added to port A, the switch will power down the PD connected to the port with the lowest priority and turn to supply power to this new PD. If more than one port has the same lowest priority, the switch will power down the PD connected to the port with larger port number.
z
manual: When the switch is close to its full load in supplying power, it will not make change to its original power supply status based on its priority when a new PD is added. For example: Port A has the priority critical. When the switch PoE is close to its full load and a new PD is now added to port A, the switch just gives a prompt that a new PD is added and will not supply power to this new PD.
After the PoE feature is enabled on the port, perform the following configuration to set the PoE management mode and PoE priority of a port. Follow these steps to set the PoE management mode and PoE priority of a port: To do…

Setting the PoE Mode on a Port PoE mode of a port falls into two types, signal mode and spare mode. z
Signal mode: DC power is carried over the data pairs (1,2,3,and 6) of category-3/5 twisted pairs.
z
Spare mode: DC power is carried over the spare pairs (4,5,7,and 8) of category-3/5 twisted pairs.
Currently, S3600 series Ethernet switches do not support the spare mode. After the PoE feature is enabled on the port, perform the following configuration to set the PoE mode on a port. Follow these steps to set the PoE mode on a port:

PoE Profile Configuration Example
Introduction to PoE Profile On a large-sized network or a network with mobile users, to help network administrators to monitor the PoE features of the switch, S3600 series Ethernet switches provide the PoE profile features. A PoE profile is a set of PoE configurations, including multiple PoE features. Features of PoE profile: z
Various PoE profiles can be created. PoE policy configurations applicable to different user groups are stored in the corresponding PoE profiles. These PoE profiles can be applied to the ports used by the corresponding user groups.
z
When users connect a PD to a PoE-profile-enabled port, the PoE configurations in the PoE profile will be enabled on the port.

Use either approach.
Note the following during the configuration: 1)
When the apply poe-profile command is used to apply a PoE profile to a port, some PoE features in the PoE profile can be applied successfully while some cannot. PoE profiles are applied to S3600 series Ethernet switches according to the following rules:
z
When the apply poe-profile command is used to apply a PoE profile to a port, the PoE profile is applied successfully only if one PoE feature in the PoE profile is applied properly. When the display current-configuration command is used for query, it is displayed that the PoE profile is applied properly to the port.
z
If one or more features in the PoE profile are not applied properly on a port, the switch will prompt explicitly which PoE features in the PoE profile are not applied properly on which ports.
z
The display current-configuration command can be used to query which PoE profile is applied to a port. However, the command cannot be used to query which PoE features in a PoE profiles are applied successfully.
2)
PoE profile configuration is a global configuration, and applies synchronously in the Intelligent Resilient Framework (IRF) system.
3)
Combination of Unit creates a new Fabric. In the newly created Fabric, the PoE profile configuration of the Unit with the smallest Unit ID number will become the PoE profile configuration for the Fabric currently in use.
4)
Split of Fabric results in many new Fabrics. In each newly created Fabric, the PoE profile configuration of each Unit remains the same as it was before the split.
