Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3
May 2002
Chapter 1 Alarm Troubleshooting
Alarm Procedures
Note When replacing a card with an identical type of card, you do not need to change the CTC
database.
Step 10 If the alarm persists, replace the reporting traffic card.
1.5.20 CTNEQPT-PBWORK
Critical, Service-affecting
The interconnection equipment failure protect payload bus alarm affects the main payload bus between
the active cross-connect XC10G card in Slot 8 and the reporting traffic card. The cross-connect card and
the reporting card are no longer communicating through the backplane. The problem exists in the
cross-connect card, the reporting traffic card, or the backplane.
Note If all traffic cards show this alarm, do a forced side switch on the active TCC-I card, as shown in Step
1, and physically reseat this TCC-I card. If this fails to clear the alarm, replace the TCC-I card. Do not
physically reseat an active TCC-I card because it disrupts traffic.
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 CTNEQPT-PBWORK Alarm
Step 1 Do a side switch from the active cross-connect XC10G card to the protect cross-connect card:
a. Determine the active cross-connect card. The ACT/STBY LED of the active card is green. The
ACT/STBY LED of the standby card is yellow.
Note You can also place the cursor over the card graphic to display a popup identifying the card
as active or standby.
b. In the node view, select the Maintenance > XC Cards tabs.
c. Click Switch.
d. Click Yes on the Confirm Switch dialog box.
Note After the active cross-connect goes into standby, the original standby slot becomes active.
This causes the ACT/STBY LED to become green on the former standby card.
Step 2 Perform a software reset on the reporting card:
a. From the node view, position the cursor over the slot reporting the alarm.
b. Right-click to choose RESET CARD.
