Hi,

     I have one WS-c2960-24TT-L which is working properly and able to configure in my office place,But the same switch I put at customer place but the switch was not working ,but the same I have taken to my office it's working.

what may be the cause,tell me how to check power issues?

how to fix it ?

I'm assuming that you tried multiple power outlets at the customer's location? Was it connected to a UPS or directly to the wall? You could take another device and connect it to the outlet that wasn't working for the switch to see if the outlet works, but otherwise it sounds like a power issue.

while connecting D-link switch its working properly,at the same power outlet while connecting the WS-c2960-24TT-L  switch its not working the power ,STAT only blinking

but switch port LED not blinking initially and after connecting ethernet cable not blinking?
