2.6.41CTNEQPT-PBWORK

Critical (CR), Service Affecting (SA)

The Interconnection Equipment Failure Working XTC Card Payload Bus (CTNEQPT-PBWORK) alarm indicates a failure in the main payload bus between the active XTC card the reporting traffic card. The XTC card and the reporting card are no longer communicating. The problem exists in the XTC card or the reporting traffic card.

Note If all traffic cards show CTNEQPT-PBWORK alarm, complete the “Reset the Active XTC Card in CTC” procedure on page 2-129for the active XTC card and then complete the “Remove and Reinsert (Reseat) the Standby XTC” procedure on page 3-3. If the reseat fails to clear the alarm, complete the “Physically Replace a Card” procedure on page 2-130for the XTC card. Do not physically reseat an active XTC card; it disrupts traffic.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

Procedure: Clear the CTNEQPT-PBWORK Alarm

Step 1 Complete the “Reset the Active XTC Card in CTC” procedure on page 2-129for the active XTC card.

Verify that the active card you reset is now standby. The ACT/STBY LED of this card should be amber, and the newly active XTC card LED should be green.

Step 2 Complete the “Reset a Traffic Card in CTC” procedure on page 2-129for the reporting card.

The reboot takes up to ten minutes.

Step 3 Verify that the reset is complete and error-free:

No new alarms appear in the Alarms window in CTC.

If you are looking at the physical ONS 15327, the ACT/STBY LED is illuminated.

If you are looking at the node view of the ONS 15327, an amber LED depiction with “Sby” has replaced the white “LDG” depiction on the card in CTC.

Step 4 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130for the standby XTC card.

Note The ACT/STBY LED of the active card is green. The ACT/STBY LED of the standby card is amber.

Step 5 If the alarm does not clear and the reporting traffic card is the active card in the protection group, complete the “Switch Protection Group Traffic with an External Switching Command” procedure on page 2-127. If the card is standby, or if you have moved traffic off the active card, proceed with the following steps.

Step 6 Complete the “Reset a Traffic Card in CTC” procedure on page 2-129for the reporting card:

While the card resets, the FAIL LED on the physical card blinks and turns off.

While the card resets, the white LED with the letters “LDG” appears on the reset card in CTC.
