When it comes to NX-OS upgrade its quite easy and simple compared to the IOS upgrade of Cisco Catalyst Switches or Cisco Routers. Recently we upgraded our Nexus 5000 Series Switches from the NX-OS version 5.0.3 to 5.2.1. In this post let’s see how to upgrade the Nexus 5000 Series Switch step by step.

Step 1

Login to Cisco Website and download the NX-OS Kick Start and NX-OS System Software files to your TFTP server.

Kickstart

Step 2

Make sure that Nexus 5000 Switch has the enough space to install the new image files by using NX-OS command “ dir bootflash”. If there is enough space you are free to install the new NX-OS image files.

Step 3

If there is no enough memory delete old image files using NX-OS command

Delete boothflash: (kickstart image name)

Delete bootflash:  (system image name)

 

SF01-MB-1256-010# delete bootflash:n5000-uk9-kickstart.5.0.3.n1.1a.bin

SF01-MB-1256-010# delete bootflash: n5000-uk9.5.0.3.n1.1a.bin

 

Step 4

Copy the new kickstart and system images to the switch bootflash by using a transfer protocol such as ftp, tftp, scp, or sftp. The examples in this procedure use tftp. Use the following NX-OS command to copy the kick start and image file

Make sure that the TFTP server is started

SF01-MB-1256-010# copy tftp bootflash:

Step 5

Enter the install all NX-OS command to install the new images, specifying the new image names that you downloaded in the Step 1 as shown below

install all command

Once all the files are installed the switch will restart and reload with the new Image files.
