10 Silicon Switch Processor (SSP) Installation and Configuration
Loading the System Software
Loading the System Software
This section presents the following topics:
• Backing up your current system software image (including learning the existing system software
image name and copying the image from Flash memory to the TFTP server)
• Copying the image from a TFTP server to Flash memory
• Verifying the new image in Flash memory
Note The SSP with 2 MB of packet memory requires Cisco IOS Release 10.0(11) or later.
Cisco IOS Releases 10.2(7) or later, 10.3(4) or later, and 11.0(1) or later, will provide the best use
of the 2-MB SSP.
Backing Up Your Current System Software and Configuration File
If you do not already have the current system software image and backup configuration file on your
TFTP server, make sure you back up these files before copying the new system software image to
Flash memory on your router.
Learning the System Image Name
To display the total amount of Flash memory present, its location, any files that currently exist in
Flash memory and their size, and the amount of Flash memory remaining, use the show flash
command. The following (typical) output displays:
Router> show flash
4096K bytes of flash memory sized on embedded flash.
File name/status
0 gs7-k.103-1
1 micro/ssp10-5
[246400/4194304 bytes free/total]
Use the file name near the bottom of the show flash command screen output (in this
case gs7-k.10-1) when you back up the image.
Backing up the Current System Image
Copy the image from Flash memory to a TFTP server using the copy flash tftp command:
Router# copy flash tftp
The router prompts you for the IP address of the TFTP server and the name of the image file you are
copying to the server.
A sample of the output for this command using IP address 1.1.1.11 and filename gs7-k.103-1
follows:
IP address of remote host [255.255.255.255]? 1.1.1.11
Name of file to copy []? gs7-k.103-1
writing gs7-k.103-1 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Router#
Use the image you backed up to the TFTP server if the upgrade image is damaged.
