PoE is not working on SM-ES3G-24-P Module

[Andrewkai]

Hello,

I am working for a voice project now. Unfortunately the PoE feature is not working in my switch Module.

When I connect to my cisco IP phone, it doesn't provide the power.

What will be the cause? Do I need to configure for PoE?

Appreciate your Help!

Sincerely,
Andrew

From what I read in the configuration guide, power should be enabled by default.

http://www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/eesm_sw.html#wp1920081

The command to configure is: power inline {auto [max max-wattage] | never | static [max max-wattage]}

You may try " sh power inline" to get an idea of what might be wrong.

Referring to the first link, the docs for configuring the module are those for the 2960:

Andrew,

Call "sh inventory" or "sh diag" and check that module PoE status.

You should check power supply also where as PoE or AC.

HTH.

Oh I see. Mine is AC power supply.

NAME: "C2911 AC Power Supply", DESCR: "C2911 AC Power Supply"

That's why switch module is not providing inline power. No wonder

So, I have to change it to PoE power supply.

Thanks a lot.

Cheer!

Hi Andrew,

How did you change the config to PoE mode from AC? Would you be ablle to share?

My router also shows:

NAME: "C2911 AC Power Supply", DESCR: "C2911 AC Power Supply"

but cant figure out how to change it to PoE.

Thanks
