Chapter 2 Alarm Troubleshooting

Alarm Procedures

Step 13 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-130for the Ethernet (traffic) card.

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

Step 14 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report

aservice-affecting problem (1-800-553-2447).

2.6.34CLDRESTART

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

The Cold Restart (CLDRESTART) condition occurs when a card is physically removed and inserted, replaced, or when the ONS 15327 is first powered up.

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 CLDRESTART Condition

Step 1 If the condition fails to clear after the card reboots, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130.

Step 2 If you reinsert a high-speed card, verify the following LED behavior:

The FAIL LED blinks for approximately 30 seconds.

All LEDs blink once and turn off.

The ACT/STBY LED is green (active).

Step 3 If the condition does not clear, complete the “Physically Replace a Card” procedure on page 2-130for the card.

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

Step 4 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
