Chapter 2 Alarm Troubleshooting

Alarm Procedures

The FSTSYNC alarm disappears after approximately 30 seconds. If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

Note FSTSYNC is an informational alarm. The alarm does not require troubleshooting.

2.6.92FULLPASSTHR-BI

Not Alarmed (NA), Non-Service Affecting (NSA)

The Bidirectional Full Pass-Through Active (FULLPASSTHR-BI) condition occurs on a nonswitching node in a BLSR when the protect channels on the node are active and carrying traffic, and there is a change in the receive K byte from No Request.

Procedure: Clear the FULLPASSTHR-BI Condition

Step 1 Complete the “Clear a BLSR Span Lock Out” procedure on page 2-127.

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.93HITEMP

Critical (CR), Service Affecting (SA) for NE

Minor (MN), Non-Service Affecting (NSA) for EQPT

The High Temperature (HITEMP) alarm occurs when the temperature of the ONS 15327 is above 122° F (50° C).

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 HITEMP Alarm

Step 1 Verify that the environmental temperature of the room is not abnormally high.

Step 2 If the room temperature is not abnormal, physically ensure that nothing prevents the fan-tray assembly from passing air through the ONS 15327.

Step 3 If airflow is not blocked, physically ensure that blank faceplates fill the ONS 15327 empty slots. Blank faceplates help airflow.

Step 4 If faceplates fill the empty slots, verify whether the air filter needs replacement. Refer to “Inspect and Maintain the Air Filter” procedure in the Cisco ONS 15327 Procedure Guide.

Step 5 If the filter is clean, complete the “Remove and Reinsert Fan-Tray Assembly” procedure on page 2-130.
