PoE setup on M4300-28G-PoE+
Hi all!
We experience an issue with a brand-new M4300 series PoE+ switch. There is no power available on the ports.
System > PoE > Basic > PoE Configuration
Power Status sais OFF, and it is read-only parameter.
System > PoE > Advanced > Port Configuration
All Ports are set to ADMIN MODE Enable.
The high Power mode, which is set to 802.3at matches the connected devices, which are expecting 802.3at.
The system is running with two power supplies, both are working properly. There is more than enough power (Watts) available for everything we want to do.
My question:
Is there a menu parameter which sets the Power Status to ON? Or does it switch to ON automatically when a PoE device is detected?
Any help is appreciated!
Chris
the replacement has arrived. I've installed the system, and it works perfectly.
Thanks for the assistance!

How do you know there is no power available? Plug one and you will see...
Standards compliant PoE power is not always "on" on PoE ports - on plugging, there is a handshake between the PO and the PD.The connedted devices don't power up. Nothing happens. (The devices itself power up and work when they are connected to a different PoE switch.) I am aware about the handshake for PoE, and that it is only provided when the device needs it.
System > PoE > Basic > PoE Configuration > Power Status ON/OFF
Should this parameter automatically switch to ON when PoE demands are detected? Because it doesn't. It is always OFF. That's why I was wondering if there is a general configuration menu to enable or disable PoE systemwide.
Hi ChristianB,
Welcome to the community! :)
Let us isolate the problem. Kindly answer the questions below:
a. What is the current firmware version of the M4300-28G-PoE+ switch?
b. Kindly try this. On the web-GUI, go to System > PoE > Basic > PoE Configuration. Select the Unit 1 box and click on Apply. Did the Status changed to "ON"? Kindly post a screenshot of what you see.
c. Have you tried to factory reset the M4300-28G-PoE+ switch? If not yet, kindly try it and see if it helps. Kindly read pages 653-654 of the M4300-28G-PoE+ switch user manual here on How to Reset the Switch to Its Factory Default Settings.
