Hi there!
In an OptiX OSN 8800 T32 subrack, the slots can house the TN17LTX board are:
IU2~IU8、IU13~IU19、IU21~IU27、IU30~IU36.
Multiple exceptions occur on your NE. I suggest you check whether the SCC board and AUX board working in subrack 0 are normal, and then check whether the NE ID is duplicate.
Thank you!
