Brocade FastIron Ethernet Switch Software Upgrade Guide - Manual (Page 33)

1. Check if the current installed management module supports the 08.0.xx software version. If not
supported, uninstall the management module and install the supported management module. For
information on installing a management module in FSX, see the Brocade FastIron SX Series
Chassis Hardware Installation Guide.
2. If you have installed a management module factory-loaded with the required software version, skip
the next step as the upgrade is complete.
3. Load the required boot code. For detailed steps, see Load the boot code on page 36.
4. Load the required flash code. For detailed steps, see Load the flash code on page 37.
NOTE
When upgrading an FSX device with the 0-Port Third Generation XL Management Module from
08.0.0x to 08.0.10 or 08.0.10a, download the flash image to the primary flash only. Downloading
the flash image to the secondary flash is not supported. Reload the device with the boot system
flash primary command to boot from the primary flash. After reload, the device automatically
copies the image to the secondary flash. After a successful upgrade to 08.0.10 or 08.0.10a,
downloading a higher software version to the secondary as well as primary flash is supported but a
mix of 08.0.10 or 08.0.10a and an older version image in the flash partitions is not supported.
Software upgrade from 07.5.xx to 08.0.01
The following limitations are applicable while upgrading from 07.5.xx to 08.0.01:
• When you load the 08.0.01 boot code on a 07.5.xx FastIron device, the device loses all boot
environment variables. As a result, you cannot use the boot system flash primary or boot
system flash secondary commands to configure boot preference. The device also ignores any
boot preference stated in the startup configuration file. Therefore, the device boots from the default
primary flash. This is only an upgrade limitation. After the completion of upgrade, the device boots
from the preferred flash partition, as configured.
• You must load the primary as well as the secondary flash with the 08.0.01 flash image. A mix of
07.5.xx and 08.0.01 images in the flash partitions is not supported.
Upgrade using a manifest file
FastIron 08.0.00a introduces a manifest file to provide a simplified upgrade mechanism from FastIron
08.0.00a to later releases, especially for units in a stack. You can use a single command to copy boot
and flash images. Using the official manifest file, the images are copied onto the devices and all the
member units are upgraded.
NOTE
Software upgrade using manifest file is supported on FCX, ICX 6610, ICX 6430, ICX 6450, ICX 6650,
and ICX 7750 standalone devices and on both homogeneous and mixed stacks.
NOTE
The manifest file upgrade process is only applicable when you upgrade a device from FastIron 08.0.00a
to a higher version. For upgrade from 07.x.xx to 08.0.xx, see
Upgrade process on page 30.
