Chapter 22 Upgrading, Downgrading, and Installing System Images
Installing System Images
Step 9 Verify that you have access to the TFTP server by pinging it from your local Ethernet port with one of
the following commands:
rommon> ping server_ip_address
rommon> ping server
Step 10 If necessary define the path and filename on the TFTP file server from which you are downloading the
image.
rommon> IMAGE=path file_name
Caution Make sure that you enter the IMAGE command in all uppercase. You can enter the other ROMMON
commands in either lower case or upper case, but the IMAGE command specifically must be all
uppercase.
UNIX Example
rommon> IMAGE=system_images/IPS-4345-K9-sys-1.1-a-7.1-3-E4.img
Note The path is relative to the default tftpboot directory of the UNIX TFTP server. Images located
in the default tftpboot directory do not have any directory names or slashes in the IMAGE
specification.
Windows Example
rommon> IMAGE=system_images/IPS-4345-K9-sys-1.1-a-7.1-3-E4.img
Step 11 Enter set and press Enter to verify the network settings.
Note You can use the sync command to store these settings in NVRAM so they are maintained across
boots. Otherwise, you must enter this information each time you want to boot an image from
ROMMON.
Step 12 Download and install the system image.
rommon> tftp
Caution To avoid corrupting the system image, do not remove power from the IPS 4345 while the system image
is being installed.
Note If the network settings are correct, the system downloads and boots the specified image on the
IPS 4345. Be sure to use the IPS 4345 image.
