Updating System Images
In some implementations of TFTP, you must create a dummy file on the TFTP server and give it read,
write, and execute permissions before copying the file over it. Refer to your TF TP docum en tati on for
more information.
Before you copy software between the network server and Flash memory in the router, do the following:
•Make sure you have access to the network server, and obtain its IP address and name.
•Verify that the server has sufficient room to accommodate the Cisco IOS system image.
•Check the filename requirements and file space of the network server.
•Create a dummy file on the server with read-write-execute permission. You copy the system image
to this file.
To create a backup of the system software on a TFTP server, perform the following steps:
Example

Updating System Images
This section provides minimal instructions for updating system images on your Cisco ONS 15530. The
default system configuration causes the system to boot automatically from the system image specified
in the BOOT environment variable. This procedure also describes now to update and manually boot the
system from a system image on a CompactFlash card. For additional information on booting options and
maintaining system images, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.
