Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide
Install a TFTP server or an RCP server application on a TCP/IP-ready workstation or PC. Many
third-party vendors provide free TFTP server software, which you can find by searching for "TFTP
server" in a web search engine.
If you use TFTP:
Configure the TFTP application to operate as a TFTP server, not a TFTP client.
–
Specify the outbound file directory to which you will download and store the system image.
–
Download the new Cisco IOS software image into the workstation or PC. See the
Download the System Image?" section on page
Establish a console session to the router. We recommend that you connect your PC directly to the
router console port. See the hardware installation guide for your router.
Verify that the TFTP or RCP server has IP connectivity to the router. If you cannot successfully ping
between the TFTP or RCP server and the router, do one of the following:
Configure a default gateway on the router.
–
Make sure that the server and the router each have an IP address in the same network or subnet.
–
See the Determining IP Addresses: Frequently Asked Questions
tech note.
enable
copy tftp flash0:
or
copy rcp flash0:
When prompted, enter the IP address of the TFTP or RCP server.
When prompted, enter the filename of the Cisco IOS software image to be installed.
When prompted, enter the filename as you want it to appear on the router.
If an error message appears that says, "Not enough space on device," do one of the following, as
appropriate:
If you are certain that all the files in flash memory should be erased, enter y twice when prompted
to erase flash before copying.
If you are not certain that all files in flash memory should be erased, press Ctrl-Z and follow the
instructions in the "Ensuring Adequate Flash Memory for the New System Image" section on
page 223.
If the error message does not appear, enter no when prompted to erase the flash memory before
copying.
