3-4 Firmware for the 1/10 Gigabit and 10-Gigabit
Ethernet Switch Modules
The firmware for the 1/10-Gigabit and 10-Gigabit Ethernet switch modules resides on a
chip on the PCB.
The switch modules have internal flash memory in two areas to hold two firmware
images. The flash area used for the normal firmware image is referred to as the
normal
area. The other flash area, referred to as the fallback area, is used to store the firmware
image for fallback purpose in case of a failure to boot from the normal area.
Firmware Upgrading Procedures
The procedures for firmware upgrading and using a fallback firmware image are listed
below.
Upgrading Firmware on the Switch using TFTP:
To upgrade the switch’s firmware, use the procedure below.
1. Copy the latest firmware to the TFTP root directory on the TFTP server machine.
2. Make sure the upgraded TFTP server and switch both have network reach ability.
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:normal
Here <ip-address> is the IP address of the TFTP server and <filename> is the name
of the firmware image file.
5. On successful download CLI displays the below string:
Firmware download completed successfully.
6. After a successful download, reboot the switch to use this latest firmware.
7. If the download fails, check the IP address, file name, network connections and
configurations to reach the TFTP server.
8. If the switch does not come up after the firmware upgrade due to any incorrect
firmware images, boot the switch using a fallback firmware image. Refer the steps in
the procedure
"Booting using a Fallback Firmware Image:" below to boot the switch
using a fallback firmware image.
9. Once the switch is booted with a fallback firmware, repeat the above steps to
upgrade with the correct firmware image.
10. On successful upgrade of the latest firmware, it is advised that you upgrade the
fallback firmware image also. Follow the steps listed in the procedure "Upgrading
Fallback Firmware using TFTP:" below to upgrade the fallback firmware image.
