Chapter 2 Alarm Troubleshooting

2.7.43 CONTBUS-IO-A

Clear the CONTBUS-DISABLED Alarm

Step 1 If the IMPROPRMVL alarm is raised, complete the “Physically Replace a Card” procedure on

page 2-154. (For general information about card installation, refer to the “Install Hardware” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.)

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL or ONS 15310-MA.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447) in order to report a Service-Affecting (SA) problem.

2.7.43 CONTBUS-IO-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: EQPT

A15310-CL-CTX A or CTX2500 card to Shelf Slot Communication Failure alarm occurs when the cross-connecting card (in this platform, the controller card) has lost communication with another card slot in the shelf. The other card is identified by the Object column in the CTC alarm window.

Clear the CONTBUS-IO-A Alarm

Step 1 Ensure that the reporting card is physically present in the shelf. Record the card type. Click the Inventory tab and view the Eqpt Type column to reveal the provisioned type.

If the actual card type and the provisioned card type do not match, see the “MEA (EQPT)” alarm on page 2-109for the reporting card.

Step 2 Complete the “Soft- or Hard-Reset an Ethernet or Electrical Card in CTC” procedure on page 2-153.

Caution Avoid soft-resetting multiple ONS 15310-MA cards at one time; doing so might cause an unexpected traffic hit.

For LED behavior, see the “2.9.2 Typical Card LED Activity During Reset” section on page 2-147.

Wait ten minutes to verify that the card you reset completely reboots.

Step 3 If CONTBUS-IO-A is raised on more than one card at once, complete the “Soft- or Hard-Reset a Controller Card” procedure on page 2-153.

Caution Avoid soft-resetting multiple ONS 15310-MA cards at one time; doing so might cause an unexpected traffic hit.

Step 4 Verify that the reset is complete and error-free and that no new related alarms appear in CTC. A green ACT LED indicates an active card.
