Software Upgrades

Dell™ PowerConnect™ 3024 Systems User's Guide

Upgrade Procedure

The application software is field upgradable. The new software must reside on a TFTP server that can be accessed by the switch.

Before you upgrade the firmware, ensure that Port Trunking is disabled.

  1. Write down the current Port Trunking configurations.

  2. Unplug all but one port from each of the trunks.

  3. Delete all trunks through the management interface.

  4. Save all configurations to NVRAM.

  5. Reset the switch to perform the firmware upgrade.

To upgrade the software, you must go to the Firmware Upgrade screen. Complete the following steps:

  1. Go to System Manager/Firmware Upgrade (in the Web or console interface).

  2. Under Boot from field, choose Net during the normal operation.

This setting allows you to try out a new version of the software before upgrading. This option runs the software from an internet location you specify in step 3.

  1. Verify information such as the IP address for the TFTP Server, Gateway IP address, and the new image filename and path.

  2. Click Apply in the Web interface or press <Ctrl><w> in the console interface.

  3. Go to the Reset screen and restart the system.

The boot routine retrieves the new image then passes control to it. The system executes the new image.

  1. If you decide to upgrade to the new image, go to the Firmware Upgrade screen again. Set the Boot from field to Net & Save and click Apply in the Web interface, or press <Ctrl><w> in the console interface.

  2. Go to the Reset screen and restart the system.

The boot routine retrieves the new image then passes control to it. The system executes the new image. The new version overwrites the old one.

  1. Verify that the software has been upgraded by going to the Firmware Upgrade screen and checking the software release information.

If the older version of the software has not been replaced, the system was unable to reach the new software and executed from the previous version.

NOTE: Perform the upgrade procedure from the console interface via an RS232 serial port. When using a telnet session or web interface alone, your connection to the switch is not available until the switch has entered forwarding mode. This takes approximately three minutes.
