NCS540X software upgrade procedure

[jigojar]

Hi,

 Can someone share the procedure for the NCS540X software upgrade/downgrade

[mivens]

Same as your question for the ASR9903, download the upgrade Method of Procedure document from CCO.
It's a PDF contained in NCS540-docs-7.3.2.tar downloadable at
https://software.cisco.com/download/home/286324675/type/280805694/release/7.3.2

[jigojar]

link is not working, can someone help

[tkarnani]

This upgrade pdf is only for specific NCS540 platforms.

[mivens]

It specifically mentions NCS540X (product ID N540X-ACC-SYS).

Check file NCS540-docs-7.3.2.tar , from 
https://software.cisco.com/download/home/286324675/type/280805694/release/7.3.2
(as mentioned above) and if the link is not working, follow this path.

Here is how we ugraded all our N540X

copy .iso image to harddisk:

then 

install package replace /harddisk:/filename.iso

when finished replacing the package (you can check by issuing show install log detail ... the info is self explanatory

then 

install apply reload

then once fully booted

install commit

All 6 of our N540X upgraded successfully with the method above

Good luck

Does this apply for versions prior 7.3.1 to 7.3.2 ?
Cisco mention :
731 is a break release due to partition changes integrated via CSCvr79738, Software
upgrade/downgrade using “install replace” or “install package replace” CLI from
7.0.x/7.1.x/7.2.x to 7.3.2 is NOT supported and will need to be done via re-image using
iPXE/USB boot

We only went to 7.1 so I was not aware of the new Cisco limitation on 7.3
