Using Redundant Control Modules Initial Configuration

Software/Hardware Versions

Make sure that the software image are the same on the primary CM and backup CM – it is possible to have two different

software images on each Control Module. If the images are not the same and fail over occurs, the image on the backup

CM may or may not be able to process the configuration of the failed primary CM.

Caution Both the primary and backup Control Modules should be of the same hardware

version, and should contain the same amount of memory.

Changing Mastership

Whenever the power is cycled on the RS, the default relationship between the primary and backup CM is reestablished.

In other words, the Control Module in slot CM (whatever its role) becomes the primary CM and the Control Module

in slot CM/1 becomes the backup CM. If a hardware fail over occurs, do not power down the RS. Instead, hot-swap

the new Control Module into slot CM. As it boots, it will assume the role of the backup CM, and will obtain its

configuration from the current primary CM. Enter the

save startup command on the primary CM. Once this file

transfer is complete, you can restore the default roles of the Control Modules by entering the

system redundancy

change-mastership

command.

Hot-Swapping

Never hot-swap a line card either in or out of the RS 32000 while the backup CM is still booting. Always wait until

both CMs are fully operational before hot-swapping line cards.
