Ensure the following criteria are set and correct prior to starting the process:
Click OK to save the settings, but leave the main TFTP Server window open.
Download the firmware from the Dell Support site located at www.premiersupport.dell.com.
The filename for the 6.0.4 firmware is 604firm.zip.
Unzip the file and place the firmware binary file (RDUx_604.fir) in the root directory of the TFTP Server (C:\TFTP-ROOT by default).
Connect to the management interface of the switch using a terminal emulation program (HyperTerminal Private Edition, Tera Term, etc.)
Browse to the System Manager/Firmware Upgrade menu.
Highlight the option for Next Boot From: and press the <Spacebar> to change the setting to Net (the default is Last Saved).
For the TFTP Server IP address option, input the IP address of the system running the TFTP Server application (this will also be shown in the bottom right-hand corner of the main TFTP Server application window).
For the TFTP Path/Filename option, input only the filename. If the file is in another folder, input the path from the TFTP root directory. (Figure 3)

Once the switch has booted, verify that the Firmware Upgrade menu now displays the new firmware version and verify that the firmware file is not corrupt by navigating through a couple of menus.
If there appears to be any problem, try downloading another copy of the firmware file and re-flash with the new file.
If there appears to be no problem with the firmware flash, navigate back to the System Manager/Firmware Upgrade menu and change the Next Boot From: option to Net & Save.
Save the settings again by pressing the <Ctrl> + <W> keys .
Press the < Esc> key to navigate back to the System Manager menu and then select the Reset option.
The switch will now boot to the new firmware from the TFTP Server and automatically save the new firmware to the flash memory. The Next Boot From: option will be changed back to Last Saved.
Once the switch has booted, verify that the Firmware Upgrade menu now displays the new firmware version.
