Upgrading a Port Extender
You can update the Dell Networking operating system (OS) on a port extender manually as needed or allow it to be
automatically updated by the controlling bridge.
Auto-Upgrade of the OS Image
An automatic OS upgrade is performed when a discovered standalone PE or PE stack is running an out-of-date or incompatible
software version compared to the OS image running on the controlling bridge. In this case, no operator intervention is
necessary. The management software automatically upgrades the PE or PE stack with the OS software version running on the
controlling bridge.
Manually Upgrading the OS Image
To manually upgrade the OS image on a standalone PE or PE stack, follow the procedure in this section.
NOTE
: You can also upgrade the OS image on a PE or PE stack as part of a global upgrade of all RPMs, line cards, and PEs
by using the upgrade all command. For more information, see the Dell Networking C9010 and C1048P Release Notes.
NOTE: The configurations shown here are examples only and are not intended to duplicate any real system or network.
1 From the C9010 console, upgrade the Dell Networking OS on a standalone PE or a PE stack using the OS version running
on the controlling bridge.
