Enter the telnet access password for the Cisco swict when requested, and then the "Enter" key.
Type "enable" at the command prompt, and then the "Enter" key.
Enter the Privileged Exec password when requested at the command prompt, and then the "Enter" key. Then enter "configuration terminal" at the command prompt, and then the "Enter" key.
Type "interface fastethernet0/1," replacing the "fastethernet0/1" with the name of an interface in which you wish to enable PoE, and then the "Enter" key. Then, while in interface configuration mode, type "power inline auto" and then the "Enter" key. Repeat this step for each interface in which PoE is required.
Type "end" at the command prompt and then the "Enter" key, copy running-config
Below is some commands to run, I don't have any power on the interface but this will show you if this is working...

Will the PoE Function of S2700/S3700/S5700 PoE Switches Be Affected When a 110 V Power Source Is Used?


When using Huawei power supply units, Huawei fixed switches supports 110 V AC input power. The power consumption of most powered devices (PDs) is 4 W to 5 W; therefore, 250 W and 500 W power supply units can provide sufficient PoE power for PDs.
NOTE:
All fixed PoE switches except the S2700-9TP-PWR-EI, S2750-20TP-PWR-EI-AC, S2750-28TP-PWR-EI-AC, S2751-28TP-PWR-EI-AC, S5700-10P-PWR-LI-AC, S5700-28P-PWR-LI-AC, S5700-28TP-PWR-LI-AC, S5700S-28P-PWR-LI-AC, S5701-28TP-PWR-LI-AC, S5700-52P-PWR-LI-AC, S5700-28X-PWR-LI-AC, and S5700-52X-PWR-LI-AC support double PoE power supply units.

The power devices that Cisco Catalyst 2960 Series Support?


The Cisco Catalyst 2960-48PST-L can support 48 PoE ports with total PoE power output capacity at 370W. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 2960-48PST-L configuration can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.

The Cisco Catalyst 2960-24PC-L can support 24 simultaneous full-powered PoE devices at 15.4W for maximum powered-device support.

The Cisco Catalyst 2960-24LT-L can support eight PoE devices at 15.4W

How to resolve PoE fault hp5400zl


Those switches have a lifetime replacement warranty. Find the number you need on this website: http://www8.hp.com/us/en/contact-hp/phone-assist.html
and have the serial number of the switch handy. have the switch plugged in and running and have a laptop and a console cable ready before you get HP on the phone. If it comes down to being a problem with a part they will either send you the part you need OR the whole switch depending on what the problem is with the switch. Most PoE faults are power supply problems. if your switch has more than one power supply be sure the connect both of them to power as HP POE switches that have more than one power supply, 1 power supply gives power to a certain portion of ports and the other power supply will give power to another portion of the ports. Much good luck!

My EAP 350 not supporting POE for more than 40 mtrs. i am using netgear prosafe POE switch. Thanks in advance


Dear Rajkuma,
As per poe 802.3 af specification only 50 Mtrs distance is supported.
If you want to cover more distance then you must purchase 1 Port PoE Repeater which Allows up to an additional 330 ft
Hope this may solve your problem.

PoE


If your switch does not support PoE, you'll have to use a power injector which should be enclosed with your router package.
connect the switch to the injector using one of the two ports in the injector (should be labeled with a small drawing or writing to differentiate which port of the two connects to the switch and which connects to the router), power the injector up, connect the other port to the router.

good luck

I am trying to add an additional PoE device, put it will not power up. How can I tell the switch to power up a specific port, or put the switch into automatic mode?


Are you within the power budget?

Power feeding of Ethernet is limited for fixed 10BASE-T/100BASE-TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 12 ports or 7.5W on 24 ports simultaneously. The Switch provides independent overload and short-circuit protection for each port, LED indicators for power status per PoE port, and supports IEEE802.3af MIB for Power over Ethernet functionality.
For each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable. Each port can provide up to 15.4W of power at the standard -48 VDC voltage.
