cisco WS-C2960C-8PC-L // issues // the first four ports don´t work

[Eduardo Ruiz chico]

i have a  cisco WS-C2960C-8PC-L , but it doesnt work fine.  it has 8 ports but just only four work correctly, 

when we connect any cable into any port, it just work when we do it in the last four port.

the first four ports doent get up the link or even PoE  

PLEASE, could you give me some light on this issue ¿?¿

Hi, do you have errors in the boot logs?

Can you execute a diagnostic test to check the ports status?

PoE module is dead.  Please organize for an RMA.

As you can see from the test the PoE for the first 4 ports have some problems:

POST: Inline Power Controller Tests : Begin
POST: inline power post failed for port 0
POST: inline power post failed for port 1
POST: inline power post failed for port 2
POST: inline power post failed for port 3
POST: Inline Power Controller Tests : End, Status Failed

As suggested from Mr. Leo Laohoo you can ask for an RMA.

Regards.
