BEFORE YOU BEGIN

Before beginning this procedure you must know or do the following:

•If you upgrade the active switch in a pair of redundant Cisco Nexus 1010s, then the standby switch is upgraded automatically.

•You have already saved a backup copy of your running configuration on an external server.

•You have saved a copy of the new Cisco Nexus 1010 software file from the following Cisco Nexus 1010 software download site to an external server:

www.cisco.com/go/1010download

---

Step 1 On the Cisco Nexus 1010, copy any unsaved configuration from the running configuration to startup so that it is preserved after the reload.

copy running-config startup-config

Example:

switch# copy running-config startup-config

[########################################] 100%

switch# 

Step 2 Copy the new software image from the external server to the following directory.

bootflash: \repository

copy scp://user@path/filename bootflash:filename

Example:

n1010# copy scp://user@linux-box.cisco.com/home/user/nexus-1010.4.0.4.SP1.1.1.iso 
bootflash: 

Enter vrf (If no input, current vrf 'default' is considered):

user@linux-box.cisco.com's password:

n1kv_license.lic                                   100%  252     0.3KB/s   00:00

n1010#

Step 3 Install the new image.

install nexus1010 full_path_to_filename

The following things occur on the switch:

•The new software image is copied to bootflash.

•Bootflash variables are updated with the names of the new system and kickstart images.

•The new image and bootflash variable information is saved in the running configuration.

Example:

switch# install nexus1010 bootflash:repository/nexus-1010.4.0.4.SP1.1.1.iso

Step 4 Save the new boot parameters in the startup configuration.

switch# copy running-config startup-config

[########################################] 100%

---

Caution If you do not copy the running configuration to the startup configuration, the new boot parameters are not saved when you reload the software in Step 5.

---

Step 5 Reload the software to refresh the Cisco Nexus 1010 software image with the new image file.

reload

The software image is replaced with the version named in the bootflash variables.
Any unsaved configuration is lost.

Example:

switch# reload

This command will reboot the system. (y/n)? [n] y
