4510R+E problem with PoE Module

[cedrick.mendes]

Hi Sirs. 

I have a catalyst WS-4510R+E, with 2 x SUP 7E, and 2 modules WS-X4748-RJ45V+E, and IOS cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin.

Now i need install one AIR-LAP1231G-A-K9 with power supply the module PoE off catalyst.

But when i connect the cable, the catalyst generate the following log:

%PM-4-ERR_DISABLE: inline-power error detected on Gi1/31, putting Gi1/31 in err-disable state

%ILPOWER-5-ILPOWER_POWER_DENY: Interface Gi1/31: inline power denied. Reason: Insufficiente inlie power, requested(31579) available(0).

could anyone give any tips?

is missing any setting?

Hi Cedrick,

This error message indicates that there is insufficiant inline power, could you please share the #show power detail output to check this issue further.

apparently everything is right.

I would say you might have insufficient power supplies for what you  have, 1400W is not much . One way to test would be during a window change the power supplies from redundant to combined and see if that fixes it .  If the chassis doesnt have enough power the card may be active but it wont supply inline power. I just noticed you only have a single supply so what I reccomended above wont work. You may need a 4000W supply .

[Leo Laohoo]

Agree with Glen.  You have a single 1400W power supply and you have TWO PoE blades.

You need to upgrade your PS with a 4kW unit (and this does not factor in PS redundancy).

Hi,

I am sorry to let you know that your PSU type PWR-C45-1400AC does NOT support PoE (ie. it is for data only), please see eg. the document beneath:

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet0900aecd801792b1.html

PSUs to support both Data and PoE are listed in the table 8 down the document (while you PSU is listed in the table 7).

Best regards,

Antonin

Thank´s sirs.

I will evaluate the cost of a new PSU with support PoE.
