Hi.
I see, you have ONS 15454 Multishelf Node.
Do you see in CTC Substending Shelf w/o problem ?
Do you try reset Control Cards on the Node Controlleand Substending Shelf ?
Cisco use FTP for data transmission beetwen NC and SS.
Do you see same error, when download SW via CTC ?
What Control Cards ans version SW do you use ?
and what version SW you download to the NE ?
