Configuring the Carrier in a Managed ONcore Hub
3-7
Hot Swapping an
ONcore Module
You can remove a module from the ONcore hub and install an identical
module in the same slot without powering off the hub. This is called a hot
swap. Whether or not you hot swap the Edge Router module affects which
configuration source the carrier uses.
When you perform a hot swap, the DMM transfers to the new carrier the
configuration used by the old carrier. The new carrier saves the settings in
its NVRAM.
The DMM transfers the configuration to the new carrier only if it has a saved
configuration for the old carrier installed in that slot. The DMM saves the
configuration when you perform one of the following:
■
Issue the SAVE command.
■
Use SNMP to make the configuration changes to the carrier. The DMM
automatically saves the changes.
■
Reset or power-cycle the DMM. The DMM automatically acquires and saves
the NVRAM configurations of all installed modules.
Swapping in a new carrier that contains a different engine from the old
carrier is still a hot swap. Only the carrier models must be the same.
