Thanks for the output.

Now which port(s) are not powering up the devices?

Can you post the output to the following commands:

sh module; and
sh interface <PORTS not powering up the devices>

hashimwajid1 · ‎06-06-2017

Thanks Leo for your Reply

* this happened with 6 ports of 48 port module on 4506-E

today i tried to reset the module by putting the below command

hw module 2 reset

it worked and solved the problem, but i am still worry, that i did not find any reason and can it happen again ?

can you explain that why did it happen ? is it a BUG or i need to upgrade the IOS or it is because Module is Faulty ?

i did not find any power consumption issue

i did not find any faulty IP Phone

CDP was enabled

nothing was configured on ports regarding power

I am eagerly waiting your Expert view on this matter

I just want to know the ROOT Cause Analysis of the issue

hashimwajid1 · ‎06-06-2017

Hi Leo

after reset the module, all ports are working. now everything is fine.

but I still did not find any reason for this issue, why this happened ?

should I upgrade the IOS or change the Module ? as it can be happen again in future ?

Regards

Hashim

I can't tell what is happening because the line card was reset.

BorislavPenchev0962 · ‎02-21-2019

Hi ,

have the same problem, would you be able to look at the logs and tell us what is the reason, we may still replace the hardware but wanted to confirm if thats required

Georg Pauwen · ‎02-21-2019

Hello,

post the logs (if you still have them) and the output of 'sh ver'. Did reseating the module solve your issue (at least temporarily) ?

BorislavPenchev0962 · ‎02-21-2019

sensitive info erased *

we did not tried to reset the module as we wanted to troubleshoot the issue first

do we need to connect anything to the ports while these are UP UP and then export sh int >

If I shut the port, the line protocol status goes to disabled. When I re-enable it, it goes to not connect.

If I plug my laptop to the port instead of the PoE device, the port goes up and I have connectivity.

Georg Pauwen · ‎02-22-2019

Hello,

I would schedule some downtime and remove/re-insert the entire module. Check if the problem persists after doing that...

BorislavPenchev0962 · ‎02-22-2019

we will try , is that a known bug , do we need to RMA the module and what warranties we have that even after module restart this issue will not appear after some time
