2911 with switch module POE issue


We got a new Cisco 2911 router (CISCO2911/K9) with a switch module (SM ES2-16-P) on it. Everything works fine after the configuration except for the power. We got 4 WAP that we will connect to the switch module that needs power. So the switch module with POE doesn't give any power out.

Do we need to enter anything to enable the POE?

here's some details:

So do I need to buy Cisco 2911 POE Power Supply (PWR-2911-POE) since our package only have Cisco 2911 AC Power Supply(PWR-2911-AC)? Can someone pls. confirm on this?

2911 with switch module POE issue

Hi redrobish,

    You would need to buy this 'PWR-2911-POE' in order for POE to work on that switch module. Thanks

Re: 2911 with switch module POE issue

I can confirm that replacing the -AC power with the -POE corrects this issue. Thanks!
