Important: In the event that an SPC/SMC requires replacement, you will need to remove the CompactFlash card from the SPC/SMC being replaced and install it onto the replacement SPC/SMC. Failure to exchange the CompactFlash card on the SPC/SMC will cause the session license to not match both SPCs/SMCs. The system will recognize that one of the SPCs match, and the session use license for the system would still be valid. However, unmatched keys would result in a loss of redundancy for all license-enabled session use and features should the remaining SPC/SMC that possesses the correctly matched license fail.
