3. Login to the Switch CLI either through Telnet or a serial console port.
4. Type the below command to upgrade the firmware in the normal area:
firmware upgrade tftp://<ip-address>/<filename> flash:fallbackl
Here <ip-address> is the IP address of the TFTP server and <filename> is the name
of the firmware image file.
5. On a successful download, the CLI displays the following string:
Firmware download completed successfully.
6. After a successful download, reboot the switch using the fallback image to verify the
fallback image. Refer to the steps listed above in the procedure
Fallback Firmware Image"
7. Once both the normal and fallback image both have latest firmware, continue to use
the normal image as directed in
Firmware Image".

Firmware Failure Recovery Steps

In case you have any issues in booting the switch with either a normal or fallback image,
use the procedure below to recover the switch functionality with a correctly working
firmware image.
Recovering Switch Functionality with a Firmware Image
1. Copy the latest firmware to the TFTP root directory on a TFTP server machine.
2. Make sure the upgraded TFTP server and switch both have network reachability.
3. Reboot the switch by power cycling the switch power.
4. During reboot, press any key when it displays the below text (as shown in

Figure 3-1.Use the "H" option to set hardware information by typing the character H.
This will display the hardware information that can be changed as shown in
Figure 3-2.
6. Configure the IP address for this switch (only for booting purposes) using the
command: ip=<IP address>
For example ip=192.168.2.3
7. Configure the subnet mask for this switch IP address using the following command:
mask=<subnet mask>
For example mask=255.255.255.0
8. Configure the TFTP server IP address using the following command:
tftpaddr=<TFTP server IP>
to boot the switch in the fallback image.
