Firmware

The firmware for Layer 2/3 1/10 and 10-Gigabit Ethernet switches resides on a chip on
the PCB.
The switch has 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 or the Network
To upgrade the switch's firmware, use the procedure below.
1. Designate a server or the network as an FTP server.
2. Copy the latest firmware to the TFTP root directory on the TFTP server machine.
3. Make sure the upgraded TFTP server and switch both have network reachability.
4. Login to the Switch CLI, either through Telnet or a serial console port.
5. Type the command below 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.
6. On successful download, the CLI displays the following string:
Firmware download completed successfully.
7. After a successful download, reboot the switch to use this latest firmware.
8. If the download fails, check the IP address, file name, network connections and
configurations to reach the TFTP server.
9. 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 to the steps
in the procedure
switch using a fallback firmware image.
10. Once the switch is booted with a fallback firmware, repeat the above steps to
upgrade with the correct firmware image.
11. On successful upgrade to the latest firmware, it is advised that you upgrade the
fallback firmware image also. Follow the steps listed in the procedure
