Catalyst 3750 upgrade--Can c3750-ipbasek9-tar.122-55.SE1.tar be delete

[Coco Liu]

Hi All,

We have a 3750 stack of two. it is with a pretty old version WS-C3750X-48 12.2(55)SE1. planning to upgrade o 

But the flash space is not enough. 

1)I am wondering whether i could delete 'c3750-ipbasek9-tar.122-55.SE1.tar' or not?  see detail below

          Directory of flash:/c3750e-universalk9-mz.122-55.SE1/

          9 drwx 5632 Mar 1 1993 01:14:13 +01:00 html
          451 -rwx 14570585 Mar 1 1993 01:14:47 +01:00 c3750e-universalk9-mz.122-55.SE1.bin

2)Show boot result  is as  below:

          BOOT path-list : flash:/c3750e-universalk9-mz.122-55.SE1/c3750e-universalk9-mz.122-55.SE1.bin
          Config file : flash:/config.text
           Private Config file : flash:/private-config.text

3)If not, could some suggest which file can be delete please?

Please initiate this command: 

archive download-sw flash:c3750-ipbasek9-tar.122-55.SE1.tar

Once the unpacking is complete, do the following: 

delete /f /r flash:c3750-ipbasek9-tar.122-55.SE1.tar
delete /f /r flash:c3750e-universalk9-mz.122-55.SE1.bin

Thanks for your reply. 

Sorry i think i  didn't explained myself clearly.

1)c3750-ipbasek9-tar.122-55.SE1.tar is already in switch flash, and  12.2(55)SE1  is the current version.  so i believe it doesn't need to be download it again with the following command ',

archive download-sw flash:c3750-ipbasek9-tar.122-55.SE1.tar

2) I would like to upgrade version to 15.2.4E10. But there is not enough space in the switch flash,:/, so i would like to delete some file to get more space for the new ISO software.

3) So I checked the flash, and I found that in flash:/c3750e-universalk9-mz.122-55.SE1/, there are four files as below, but in fact only the 2nd one(c3750e-universalk9-mz.122-55.SE1.bin) has been used for system boot, so I was wondering whether I could delete the forth(c3750-ipbasek9-tar.122-55.SE1.tar) one or not?  I am wondering whether switch could be reversed to current version  or not  without ''c3750-ipbasek9-tar.122-55.SE1.tar'. 

Here is show boot result:

.tar file only used as a source to support IOS installation, i.e. it's not needed, but, if possible, as it may no longer be available from Cisco, suggest you save it elsewhere before you delete it.

If you still need space, often you can remove running IOS, as it's only used during boot load. (Of course, if you don't have a valid .bin to load, switch won't boot.)

Yes and no.  Yes, the BIN file is already there, however, it does not hurt to unpack the TAR file because it will also unpack the HTML files too.  Next, it is easy to mistakenly delete the BIN file in the main directory but the BIN file in the sub-directory (if the file is correctly extracted from the TAR file) requires some bit of effort.

Alright, just humour me a bit, OK?  

First, unpack the IOS from the TAR file (just as I laid out the instruction).  Next, delete the BIN and TAR file from the main directory.  Leave the IOS in the sub-directory alone. 

Finally, upgrade the IOS correctly using the following command: 

arch download-sw /OVERWRITE tftp://IP_ADDRESS/c3750e-universalk9-tar.152-4.E10.tar

Please observe what this command will do -- Pay close attention to the "sh boot" command before and after.
