IOS Booting from usb flash

[pongx2kim]

Hi I'm Kim student from South Korea.

An error occurs during initialization and booting of the switch.

The switch is ws-c2960x-48ts-l, and I think all the ios are missing during initialization.

I tried to download and install the image file on usb, but the following problems occurred.

     switch: boot usbflash0:c2960x-universalk9-mz.152-2.E7.bin
     Loading "usbflash0:c2960x-universalk9-mz.152-2.E7.bin"...usbflash0:c2960x-universalk9-mz.152-2.E7.bin: bad file number

     Error loading "usbflash0:c2960x-universalk9-mz.152-2.E7.bin"

     Interrupt within 5 seconds to abort boot process.
     Boot process failed...

     switch:

Even though I didn't get the file name wrong, I couldn't solve it. Do you know what the problem is?

Thank you

Hi,

download IOS from official site again and match the checksum before use. this message says, file is not able to load

Is this really a 2960X?

how do you check the checksum and how do you match it?
