AP 2602 Problem with Code 7.4.100.60

[M.Netuschil5148]

Hi at all,

I have problems with the code 7.4.100.60 and 2602 AP´s.

The AP´s stops delivering services and no client can connected to them. After a reboot

all problems are solved, but this problem comes back every ten days.

In the logs are only shown a disconnect from these AP´s on the controller.

On the AP´s is nothing to find.

Is this a known problem? Is there a workaround available?

Thanks in advance,

Mario

IF the APs are connected to a Cisco PoE switch, what output to do you get when you issue the command "sh power inline"?

Here are the screenshoot:

Oh no.  I meant when the APs "disconnect" from the WLC, is the above screenshot output the same?

Ok so I must wait until one of this AP´s run in this state.

Thanks

Yes.  That's right.  When one (or more) of the APs has "disconnected" from the WLC, and you've got a Cisco PoE switch, post the output to the command "sh power inline".  I want to see if the output is "IEEE" or something else.

if you have other models without same issue, this is known issue on current 7.4 code, only impact 1600/2600/3600 APs and 2.4 G .

but the AP should not disconnect, it is a radio issue.

or it might be different thing, get AP event.log in flash.

Hello Mario,

As per your query i can suggest you the following solution-

Please check the powering options-

• 802.3af Ethernet Switch

• Cisco AP2600 Power Injectors (AIR-PWRINJ4=)

• Cisco AP2600 Local Power Supply (AIR-PWR-B=)

and Power Draw

AP2600: 12.95W

Note: When deployed using Power over Ethernet (PoE), the power drawn from the power sourcing equipment will be higher by some amount depending on the length of the interconnecting cable. This additional power may be as high as 2.45W, bringing the total system power draw (access point + cabling) to 15.4W.

Hope this will help you.
