Must the system software match the type of the SRU installed on an AR2240 subrack or an AR3260 subrack

24

In scenarios where different SRUs may be installed on the AR2240 subrack or the AR3260 subrack, the system software does not need to match the type of the SRU. On an AR2240 subrack, the system software of AR2240 is used no matter what type of SRU is installed on the subrack. On an AR3260 subrack, the system software of AR3260 is used no matter what type of SRU is installed on the subrack.

You do not need to use different system software versions to match different SRUs. The same system software is used on AR2204-27GE, AR2204-27GE-P, AR2204-51GE-P, AR2204E, AR2240C, no matter which type of SRU is installed. This is true for AR3260.

Communication between a newly installed OptiX OSN 8800 subrack and existing subracks
If the newly installed subrack is configured as the slave subrack, connect the ETH port on the EFI board of the subrack to the ETH port on the EFI board of the existing subrack. If the newly installed subrack is configured as the master subrack, use extended ECC or SC2 for communication.

Difference between enhanced subracks and general subracks
