If Switch is in recovery mode :

Stick USB into Switch with the required IOS loaded. Run the command “boot”, this will look for a
compatible IOS withing the USB and intall it.

Now continue with the update process of both the stack switches. Displaying Available File Systems :

To display the available file systems on your switch, use the show file systems privileged EXEC
command as shown in this example for a standalone switch:


Switch# show file system

Under 2nd line “31440470016  31296831488    disk            rw        disk1:”
if it say’s “Unknown“, this means the USB pen drive inserted is uncompatible or not formatted
to fat32 partition”.


To see the contents within the USB pen inserted into Cisco hardware :

Now let’s copy the IOS from USB over to FLASH0:

copy usbflash01:c2960x-universalk9-mz.150-2.EX5.bin flash1:

Check to see if IOS is copied from USB to Flash1:

no IOS c2960x-universalk9-mz.150-2.EX5.bin found on Flash2:

This will copy IOS from USB over to Flash1: which is stack 1 on the 2960x.

Repeat the steps for Flash2: on stack 2 from the same console session.

copy usbflash01:c2960x-universalk9-mz.150-2.EX5.bin flash2:

Finally we need to tell the Switches to boot the new loaded IOS :

config t
boot system c2960x-universalk9-mz.150-2.EX5.bin

or

#boot system switch all flash1:c2960x-universalk9-mz.150-2.EX5.bin

Reload the Primary and Secondary Stacks.

This completes this exercise.
