Chapter 2 Alarm Troubleshooting

2.7.59 EQPT-MISS

Step 3 If the CTC reset does not clear the alarm, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-154for the reporting card.

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

Step 4 If the physical reseat of the card fails to clear the alarm, complete the “Physically Replace a Card” procedure on page 2-154for the reporting card.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Step 5 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.

2.7.59 EQPT-MISS

Default Severity: Critical (CR), Service-Affecting (SA)

SONET Logical Object: FAN

The Replaceable Equipment or Unit Missing alarm is reported against the fan tray within the ONS 15310-CL or ONS 15310-MA. It indicates that the fan is not operational, or that the

ONS 15310-MA fan tray is not present. For an ONS 15310-CL, this alarm is not user-serviceable. For the ONS 15310-MA, complete the fan tray replacement procedure located in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

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.

2.7.60 ERFI-P-CONN

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

SONET Logical Objects: STSMON, STSTRM

The Three-Bit (Enhanced) Remote Failure Indication (ERFI) Path Connectivity condition is triggered on DS-1, DS-3, or VT circuits when the “UNEQ-P” alarm on page 2-142and the “TIM-P” alarm on page 2-139are raised on the transmission signal.

Clear the ERFI-P-CONN Condition

Step 1 Complete the “Clear the UNEQ-P Alarm” procedure on page 2-142and the “Clear the TIM-P Alarm” procedure on page 2-139. This should clear the ERFI condition.
