Images and procedures required

The software images required and the procedures for upgrading have been changed as described in the
following sections:

 Upgrading Software Images as Required by Version – This sub-section describes the

procedures required for your software upgrade depending upon the version you are upgrading
from or to. Links are provided to the required procedures as required.

 Displaying the Flash Memory and Version Information – This sub-section describes the

commands that allow you to determine the contents of the BigIron RX Series switch’s flash
memory and how to read the output of those commands.

 Upgrading the device’s Monitor and Boot Images – This sub-section describes the procedures

required for upgrading the BigIron RX Series Switches Monitor and Boot software images.

 Upgrading the device’s Multi-Service IronWare Image – This sub-section describes the

procedures required for upgrading the BigIron RX Switches Multi-Service IronWare software
image.

 Rebooting the device – This sub-section describes the procedures required for rebooting the

device after upgrading the software images.

Upgrading the Multi-Service IronWare software

When performing this upgrade, you will usually only need to upgrade Multi-Service IronWare image. The
Boot and Monitor images will only need to be upgraded as specifically directed in the relevant release
notes.

The steps for this upgrade include the following:

1. Determine the versions of the software images currently installed and running on the switch.

2. Upgrade the Device’s Multi-Service IronWare Image.

3. Reboot the BigIron RX Series switch.

In most cases, this is all that will be required. If you are directed by the release notes to upgrade the
Monitor or Boot images, use the following procedures:

4. Upgrade the BigIron RX Series switches Monitor and Boot images.

5. Reboot the BigIron RX Series Switch.

Release Notes v 1.0 Page 11 of 46

Displaying flash memory and version information

Prior to upgrading the images on a BigIron RX Series switch, it is advisable to check the versions already
installed. This allows you to determine which versions need to be upgraded. It is also useful to check the
versions installed immediately after an upgrade has been done to make sure that you have installed the
versions required in your installation. The following sections describe how to use the show flash and
show version commands to display this information.

Displaying flash information

You can display information concerning the contents of a BigIron RX using the show flash command as
shown in the following:
