This article describes how to apply firmware upgrade for the NSM/SonicCore build in a closed network environment.
Must be on minimum build 2.3.3-674. Any prior build will require a rebuild of the NSM/SonicCore server or an upgrade from the system upgrade option.
*If using NSM HA begin upgrade process with the active node first. The standby will take over as active while upgrading the first node. Once first upgrade is complete, wait until it comes back and is showing in standby mode. Now do same upgrade process for the current active node and the standby will take over as the active unit.
