I have in my lan 4 switches WS-C2960-24TT-L and recently my company is buying IP Avaya Hardphones.
They need a power supply. Avaya tells me that I should enable POE in my switch for the telephones can be able to receive power.
I search everywhere , but I could´t finf information if this switches supports (or not) POE.
I figured it out to access the por configuration. But when I type POWER INLINE , OR POWER command, or Show Power Inline, insede the terminal configuration , y Receive "Invalid input detectedat market" (I am attaching a link image of th error)
Is it posible that this switch does not support POE?
In the future, you can also run the command "show power inline" or "show env power" and you can see if a PoE power supply is in this device. If there is PoE power supply it will state the available PoE power.
However, the WS-C2960-24TT-L does not support PoE. Look at the link below:
