Cisco 2811 PoE Power Supply

Unanswered Question
Oct 1st, 2008

Hi, What command is used to remotely discover if a 2811 has a PoE power supply installed. I have tried both the "show diag" and "show env" commands but cannot find a definitive answer.



I have this problem too.

Do you have an Layer 2 card in the c2811 (something like NM-16ESW in the NME port)?

Please paste here the output of "show version" to be able to help.

Hi Glen,

Does "show power available" give you anything? I've not 28xx with a switch modulbe installed to check, but that command works on POE enabled switches.
