Hello guys, I'm trying to configure a stack between two WS-C2960S-48FPS-L but does not working.

The switch port is always Down.

I tried to change de module and cables.

I tried to make a loop in one of two switches and the ports always down.

IOS: 12.2(55)SE5

#show switch stack-ports

  Switch #    Port 1       Port 2

  --------    ------       ------

    1          Down         Down

Anyone could help me please?

Thanks in advance.

Ohhhhh ... THAT error message.  Now it makes sense.  LOL

Power down your switch, remove the stacking module.

GIVE IT A FEW SLAP and put it back in.

Hi leolaohoo,

I saw this error on my logging now:

If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under your warranty or under a Cisco technical support program such as Smartnet.  Please contact Cisco's Technical Assistance Center for more information.

Did the flex stack module/cable come with the switch or you purchased it separately?

I had restarted this switch before, and this message does not appeared and the stack does not worked.

This message appeared after I try to remove and put the stackmodule with switch powered.

Even without this message the stack port always Down.

Thanks

Judging from the serial number, I say you purchased the switch after April 2012.  So if you still can't get it to work, get Cisco to RMA you a new stacking module.

Just want to let you know that you can stack UP TO four 2960S in a stack.  You can't stack five or more.

I agree with Leo,  If you have warranty on this switch, just open a ticket with TAC and RMA to Cisco.  Let them take care of their defective product.
