Alarm Procedures
Note When replacing a card with an identical type of card, you do not need to change the CTC
database.
1.5.18 CONTBUS-B-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 11 lost communication with the coprocessor on the TCC-I card in Slot 7. The problem is
with the physical path of communication from the TCC-I card to the reporting TCC-I 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.
Procedure: Clear the CONTBUS-B-18 Alarm on the TCC-I Card
Step 1 Position the cursor over the TCC-I card in Slot 11.
Step 2 Right-click and choose RESET CARD to make the TCC-I in Slot 11 the active TCC-I card.
Step 3 Wait approximately two minutes for the TCC-I in Slot 7 to reset as the standby TCC-I card. Verify that
the Standby LED is lit before proceeding to the next step.
Step 4 Position the cursor over the TCC-I card in Slot 7.
Step 5 Right-click and choose RESET CARD again to make the TCC-I in Slot 11 the active TCC-I card.
Step 6 If the alarm reappears when the TCC-I in Slot 11 reboots as the active TCC-I, the TCC-I card in Slot 11
is defective and must be replaced.
Note When replacing a card with an identical type of card, you do not need to change the CTC
database.
1.5.19 CTNEQPT-PBPROT
• Critical, Service-affecting
The interconnection equipment failure protect payload bus alarm indicates a failure of the main payload
between the protect cross-connect XC10G card in Slot 10 and the reporting traffic card. The
cross-connect card and the reporting card are no longer communicating through the backplane. The
problem exists in either the cross-connect card, the reporting traffic card, or the backplane.
