Chapter 2 Alarm Troubleshooting

Alarm Procedures

•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 8 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130for the traffic card.

Step 9 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

2.6.174 SWTOPRI

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

The Synchronization Switch to Primary Reference (SWTOPRI) condition occurs when the ONS 15327 switches to the primary timing source (reference 1). The ONS 15327 uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference.

Note SWTOPRI is an informational condition. It does not require troubleshooting.

2.6.175 SWTOSEC

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

The Synchronization Switch to Secondary Reference (SWTOSEC) condition occurs when the ONS 15327 has switched to the secondary timing source (reference 2). The ONS 15327 uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference.

Procedure: Clear the SWTOSEC Condition

Step 1 To clear the condition, clear alarms related to failures of the primary source, such as the SYNCPRI alarm (see page 2-117).

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).

2.6.176 SWTOTHIRD

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

The Synchronization Switch to Third Reference (SWTOTHIRD) condition occurs when the ONS 15327 has switched to the third timing source (reference 3). The ONS 15327 uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference.
