Schedule the upgrade when the fabric is stable and steady. Ensure that everyone who has access to
the switch or the network is not configuring the switch or the network during this time. All
configurations are disallowed at this time.
Space
•
Verify that sufficient space is available in the location where you are copying the images. This
location includes the active and standby supervisor module bootflash: (internal to the switch).
• Hardware
Avoid power interruption during any install procedure. These kinds of problems can corrupt the
software image.
• Connectivity (to retrieve images from remote servers)

Standby supervisor module bootflash: file system (see
–
Internal bootflash: offers approximately 200 MB of user space.
–
– Configure the IPv4 address or IPv6 address for the 10/100/1000 BASE-T Ethernet port
connection (interface mgmt0).
1000 BASE-T Ethernet is only available on Supervisor-2 modules.
– Ensure the switch has a route to the remote server. The switch and the remote server must be in
the same subnetwork if you do not have a router to route traffic between subnets.
– Ensure that the specified system and kickstart images are compatible with each other.
– If the kickstart image is not specified, the switch uses the current running kickstart image.
– If you specify a different system image, ensure that it is compatible with the running kickstart
image.
– Retrieve images in one of two ways:
Local file—images are locally available on the switch.
Network file—images are in a remote location and the user specifies the destination using the
remote server parameters and the file name to be used locally.
