Customer Service
Before performing any software upgrade, contact your respective customer service representative to
review your software upgrade requirements and to provide recommendations based on your current
operating environment.
If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you
purchased support directly from Cisco, contact Cisco Technical Support at this URL:
Scheduling
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 will be 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 modules or bootflash: (internal to the switch).
Ensure that the required free space is available for the image files to be copied.
Hardware
Avoid power interruption during any install procedure. These kinds of problems can corrupt the
software image.
Connectivity (to retrieve images from remote servers)
Configure the IP address for the 10/100 BASE-T Ethernet port connection (interface mgmt0).
–
– Ensure that the switch has a route to the remote server. If you do not have a router to route traffic
between subnets, the switch and the remote server must be in the same subnetwork. Verify
connectivity to the remote server.
Images
The specified system and kickstart images must be 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.
Images can be retrieved in one of two ways:
–
Local—Images are locally available on the switch.
Remote—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.
