How to Install, Upgrade, or Downgrade NME-NAM-120S
Upgrading or Reinstalling NAM Software
During software upgrades, you use the Bootloader, a small set of system software that runs when the
system first powers up. The Bootloader loads and runs the NAM application. The bootloader might
optionally load and run the helper image on flash memory.
Reinstalling software involves installing, configuring, and starting a helper image. The helper, in turn,
starts the NAM installation wizard, which installs the software.
Note Plan software upgrades or downgrades for times when you can take all applications that run on the host
router out of service or offline.
NAM Software Images
The NME-NAM-120S contains three NAM software images:
• Bootloader image in flash memory—Use to specify whether to boot the NAM application image or
the helper image
• Helper image in flash memory—Use to recover or upgrade NAM software images
• NAM application image on the hard drive—Source of the NAM Traffic Analyzer and NAM CLI
Types of NAM Software Upgrades
NAM software upgrades are available in two forms:
• Images—Full image releases that are installed from the helper image. Full image upgrades are
typically used to update the NAM application image, and if necessary and recommended by
technical support, you can also use the helper image to upgrade the bootloader image or helper
image.
• Patches—Incremental updates to software versions that are installed with the patch NAM CLI
command. Patches are available only for the NAM application image.
Perform one of the following procedures in this section, depending on whether you are adding a patch
to your NAM application or are performing a full software image upgrade:
• Upgrading the NME-NAM-120S Application Image (Full Image), page 13
• Upgrading the NAM Application Image — Patch, page 16
