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.
