1.5.16 CONTBUS-A-18
• Major, Non-service affecting
The communication failure from TCC-I slot to TCC-I slot alarm means the main processor on the TCC-I
card in Slot 7 has lost communication with the coprocessor on the second TCC-I card in Slot 11. The
problem is with the physical path of communication from the TCC-I card to the reporting card. The
physical path of communication includes the two TCC-I cards and the backplane.
Caution Always use the supplied electrostatic discharge wristband when working with a powered
ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge
of the shelf assembly.
