Chapter 2 Alarm Troubleshooting

Alarm Procedures

Procedure: Clear the MANUAL-REQ-RING 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).

2.6.126 MANUAL-REQ-SPAN

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

The Manual Switch Request on Span (MANUAL-REQ-SPAN) condition occurs on BLSRs when a user initiates a MANUAL SPAN command to move BLSR traffic from a working span to a protect span.

Procedure: Clear the MANUAL-REQ-SPAN 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).

2.6.127 MEA (EQPT)

Critical (CR), Service Affecting (SA)

The Missing Equipment Attributes (MEA) alarm for equipment is reported against a card slot when the physical card inserted into a slot does not match the card type that is provisioned for that slot in CTC. Removing the incompatible cards clears the alarm.

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 MEA (EQPT) Alarm

Step 1 Physically verify the type of card that sits in the slot reported in the Alarms window MEA alarm Object column.

Step 2 In CTC, click the Inventory tab to reveal the provisioned card type.

Step 3 If you prefer the card type depicted by CTC, complete the “Physically Replace a Card” procedure on page 2-130for the reporting card.

Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
