how to upgrade a WS-C2960CX-8PC-L to IOS Release 15.2.7E3 MD

[dbov68]

Hi,

I try to upgrade the existing IOS 15.2(4)E2 to an Release 15.2.7E3 for a switch WS-C2960CX-8PC-L.

command to do the upgrade:
archive download-sw /overwrite /reload tftp://172.16.11.125/c2960cx-universalk9-mz.152-7.E3.bin

!!test TFTP
SW_01#copy running-config tftp://172.16.11.125/config.txt
Address or name of remote host [172.16.11.125]?
Destination filename [config.txt]?
!!

!!start upgrade
SW_01#$/reload tftp://172.16.11.125/c2960cx-universalk9-mz.152-7.E3.bin

I tried some older release with the same issue

The solution is to open a TAC case ?

Thanks for the help

Correct intention but wrong filename.  

The filename needs to be TAR.

NOTE:  Use the /imageonly to push the BIN file only (HTML files will not be unpacked).

I downloaded fresh the tar file from cisco site (png file attached)

sh ver

Model number : WS-C2960CX-8PC-L

op Assembly Revision Number : B0
Version ID : V03
CLEI Code Number : CMMT410BRB
Hardware Board Revision Number : 0x09

Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 12 WS-C2960CX-8PC-L 15.2(4)E2 C2960CX-UNIVERSALK9-M

It seem to be the good file for the good device

Best regards

Daniel

Uhhhhh ... Did someone renamed the file to a "TAR" extension? 

Because that filename is definitely not correct. 

Download the TAR file from the Cisco website (and not rename it).

Thanks Leo,
I apologize, I had a bad copy/paste.

With the good string it works better "archive download-sw /overwrite /reload tftp://172.16.11.125/c2960cx-universalk9-tar.152-7.E3.tar"

Best regards
Daniel
