Fabric Extender Image Management

No software ships with the Cisco Nexus 2000 Series Fabric Extender. The Fabric Extender image is bundled
into the system image of the parent switch. The image is automatically verified and updated (if required)
during the association process between the parent switch and the Fabric Extender.
When you enter the install all command, it upgrades the software on the parent Cisco Nexus Series switch
and also upgrades the software on any attached Fabric Extender. To minimize downtime as much as possible,
the Fabric Extender remains online while the installation process loads its new software image. Once the
software image has successfully loaded, the parent switch and the Fabric Extender both automatically reboot.
This process is required to maintain version compatibility between the parent switch and the Fabric Extender.
