Redundant NI2 will not become
active
Be sure that you have enabled the command no auto-sync bootflash in the redundancy
configuration mode if you are using OC3 NI2's with different product numbers (for
example, an NI2-155SM-155SM or NI2-155MM-155MM with an NI2-155SM-155SM2
or NI2-155MM-155MM2). Different types of NI2's require different bootflash image
types to operate properly.
