PoE+ on 2960S 1

[disturbedone]

I have just got a 2960S-24PS-L as I require the PoE+ to power a Meru Access Point (AP433i). The AP requires PoE+ to power the 3 radios whereas all other APs (AP320i) only require standard PoE for their 2 radios.

I have plugged the AP in and it works but only has 2 radios working. The GUI for the 2960 shows the port only using 15.4W ie standard PoE.

What needs to be done to get the switch to send more power to the AP?

In the detail below, ports 1-3 are standard APs and port 4 is the new AP. It's detecting it as Class 4 but not pulling any extra power.

Any ideas?

Non-cicso endpoint cannot use CDP messages to negotiate, also make sure the "power inline static max" is not configured. The " power inline consumption 30000" should fix the port to 30watts in case the auto function does not work.
Make this number the actual max.

Example:
Switch(config)# interface gigabitethernet2/0/2
Switch(config-if)# power inline consumption 12000
%CAUTION: Interface Gi1/0/2: Misconfiguring the 'power inline consumption/allocation'
command may cause damage to the switch and void your warranty. Take precaution not to
oversubscribe the power supply. Refer to documentation.

Thanks. I ran

switch(config)#interface gigabitEthernet 1/0/4 
switch(config)#power inline consumption 29999

and it appears have powered the 3rd radio in the AP.

I had to use 29999 as when using 30000 it would not stay in the config. It would accept the command but show run would not show this on the port. Any ideas why?

 

[telcoguy]

Just guessing, but i think it may still see it as default, and therefor hides it. "show run all" should show you hidden default commands as well.

Interestingly if I have power inline consumption 29999 on the port that shows in show run but if I have power inline consumption 30000 it doesn't show in show run but it does show in show run all. If I have it set to 30000 then show power inline shows the power back to 15.4W which is the default but I have it at 29999 it shows it at 30.0W
