Contact Cisco TAC. The switch is dead.

johnlloyd_13 · ‎02-20-2017

hi,

before RMA with TAC, could you try:

switch: flash_init
switch: boot flash:c2960x-universalk9-mz.152-2.E6.bin

or revert to old IOS

switch: boot flash:c2960x-universalk9-mz.150-2.EX5

huucuonghumg · ‎02-20-2017

Are you able to enter the rommon mode ?

huucuonghumg · ‎02-20-2017

Dear Satwant Singh,

I cannot enter to rommon mode.

Satwant Singh · ‎02-20-2017

Dear huucuonghumg,

As Leo Laohoo suggested, better to contact with TAC

huucuonghumg · ‎02-21-2017

thanks Leo Laohoo and Satwant Singh

i will try contact with TAC

Did you try booting off USB Flash

Format your USB flash drive with a FAT file system. ...
Copy the system IOS image to the USB flash drive.
While the Switch is powered off, plug in the USB flash drive to the USB port on the router.
Power on the Switch and when it starts to boot up press the Break key to enter ROMMON mode

Otherwise you can contact TAC support and replace the product

cannot boot switch cisco 2960X, reboot loop
