Upgrading Dell PowerConnect 54xx switch firmware

This is the procedure we can use to upgrade the firmware of, for example, PowerConnect 5448 and PowerConnect 5424 switches.

You should have set up a tftp server in same network as switch admin ip is.

First, connect to to your switch via ssh or serial cable (COM) and enable privileged commands:

> enable

Copy new firmware from your tftp server:

# copy  tftp://tftp_server_ip/switch/powerconnect_54xx-20046.ros image


# copy tftp://tftp_server_ip/switch/powerconnect_54xx_boot-2000.rfb boot

Now, you should view the new firmware image ready, but not active:

Select image-2 as active for the next boot:

# boot system image-2

The image is selected as active for the next system boot (note that the asterisk now is on non active text):

Now, we only have to reload the switch to boot with updgraded image.

# reload

In this way we can upgrade several switches and in all of them the switch configuration will be preserved.
