I have a 2F-BLSR and I upgraded from TCCs to TCC2s. All went well until I went to remove my locks from the spans, but it just locks up the whole network in that I have to reset (physically or manually) the TCC cards to get back to CTC!
I can clear one segment with no issues, but the second one hangs the system as above.
Fiber is running clean, zero errors.
Is there something I should look for or an order to bringing the ring back up to fully protected? It is running unprotected now.
Which control cards were you starting from, TCC or TCC+? I don't believe it would be possible to directly upgrade from a TCC to TCC2 without using a TCC+ card in-between (due to software compatibilites). The TCC is compatible up to 2.x, The TCC+ up to R4.1, the TCC2 starts at R4.0.
