show power-injector issue (Bridge 1410)

[Yde Ihop]

Hello All,

We have set up a point to point link using two 1410 wireless bridges. The connection has been working for more than 1 year without a major issue.

This morning, we have noticed  that on one of the bridge the result of the show power-injector is as follows:

#sh power-injector

=========== Power Injector Statistics ===============

==Power Injector port 0 is disabled

==Power Injector port 1 is disabled

==Power Injector port 2 is disabled

==Power Injector port 3 is disabled

==Power Injector port 4 link down

==Power Injector port 5 is disabled

==Power Injector port 6 is disabled

Both bridges are associated. The problem is that you can't ping the bridge that displayed the aforementioned command through its power injector. We have even replaced the power injector with a  new one and we are still facing the same issue.

Both bridges are using the following image c1410-k9w7-mx.124-21a.JY.

Did someone has encountered the same issue and how did he/she fix it ?

Thank you,

[Saurav Lodh]

Hi,

Actually port on the power injector switch are in auto-duplex and auto-speed mode
you need to ensure external devices which you connected to power injector switch ports are not hardcoded in full-duplex, they needed to be in auto-duplex mode.
because in result of duplex mismatch you connection could be slow down and even ports may shutdown.

and also check both bridge with the latest firmware release
Cisco Aironet equipment operates best when you load all components with the latest version of the software. 
You can download the latest software and drivers from the Wireless Downloads Page ( registered customers only) .
