Cisco Firmware Update

[hainhtetaung]

Hi Expertise,

I was trying to firmware update to Cisco 3750 stack switches.

I can copy to Flash1: of Switch 1 and successful.

However trying to copy to Flash2:, facing one the issue flash is full. When I check dir flash2 , find out one file 23052009.cfg

Is it safe to delete???

this is a configuration file.

someday, you copied the config file to flash

you have switch backups on an external fodler? tftp server?

You can also delete the following files:

- config.txt.backp

-private-config.text.backup.

but the solution is not that ... because the flash is short (now you have 2MB free and normal ISO need 11MB)... you have to delete the original ISO (c3750-ipservicesk8-mz.122-55.SE5) !

for delete:

delete /force /recursive flash2:c3750-ipservicesk8-mz.122-55.SE5

I agree with Tiago, i.e. that your principle problem is you need to remove the existing IOS image to free sufficient space for the replacement image.  BTW, Tiago has a typo in the name of the existing directory.

Normally, you don't need to worry about tens of KB for some config files, but it appears you have a 3750 with only 16 MB flash.  For those, with later IOS images, flash space can be very tight.
