Important software upgrade considerations
6
General upgrade considerations
•
The combined interface module FPGA image can exceed 32 MB, which is greater than the file
size limit in older versions of TFTP server applications. Before using TFTP to transfer image
files, be sure that you are using an updated TFTP server capable of handling larger file sizes.
•
In most cases boot and monitor images do not need to be upgraded, regardless of whether you
are using the combined IronWare image, or are copying images to the management module
and interface modules individually. Do not upgrade boot or monitor images unless you are
explicitly instructed to do so in the upgrade instructions for the version you are using.
•
Hitless OS upgrades are only supported for upgrades within the same major software release.
Hitless OS upgrades are not supported for upgrades from one major release to another major
release. For more information about hitless upgrades, refer to “Hitless IS Upgrades”.
Special upgrade information for PowerConnect B-MLXe routers
•
PowerConnect B-MLXe routers require a minimum software release of R05.1.0.
•
In rare circumstances, you may receive management modules that are running Pre 5.1.0 code.
In this instance, follow the instructions below to upgrade the management module and the
MLXe router to R05.1.00.
Interface module software upgrade considerations
The following sections contain important upgrade information for interface modules.
Interface module FPGA image upgrade considerations
NOTE
You must use FPGA images that are specified for PowerConnect B-MLXe series routers. Use of FPGA
images intended for other products will render your chassis inoperable.
The following rules apply when upgrading FPGA images on interface modules:
•
FPGA images on interface modules must be compatible with the software version running on
the router.
•
You can upgrade FPGA images
•
individually, or upgrade all FPGA images using the combined FPGA image.
•
When you copy the
•
combined FPGA image from to the management module, the management module selects the
FPGA images to be downloaded based on the types of interface modules installed and checks
for duplicates before downloading the images.
•
The FPGA upgrade utility compar
•
es the FPGA image version currently installed to new images being downloaded. If the versions
are identical, the download is aborted and a warning message is displayed. You can use the
force-overwrite option with the FPGA upgrade command to override this feature.
•
The bundled FPGA image is more than 32 MB in size. If you are using a TFTP server, be sure
that it is capable of handling larger file sizes.
