Chapter 1 Alarm Troubleshooting
The alarm raises when the OC-192 card temperature exceeds 90 degrees Centigrade. The internal
equipment automatically shuts down the OC-192 laser when the card temperature rises to prevent the
card from self-destructing.
Procedure: Clear the AUTOLSROFF Alarm
Step 1 Read the temperature displayed on the ONS 15454 LCD front panel.
Step 2 If the temperature of the ONS 15454 exceeds 90 degrees Centigrade, complete the “Clear the HITEMP
Alarm” procedure on page 1-43.
Step 3 If the temperature of the ONS 15454 is below 90 degrees Centigrade, replace the OC-192 card.
Note When replacing a card with an identical type of card, you do not need to change the CTC
database.
Step 4 Call the Technical Assistance Center (TAC) at 1-877-323-7368 to discuss the case and if necessary open
a returned materials authorization (RMA) on the original OC-192 card.
1.3.14 AUTORESET
• Minor, Non-service affecting
The card is performing a warm reboot automatically. An AUTORESET occurs when you change an IP
address or perform any other operation that causes an automatic card-level reboot.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf
assembly.
Procedure: Clear the AUTORESET Alarm
Step 1 Check for additional alarms that may have triggered an automatic reset.
Step 2 If the card automatically resets more than once a week with no apparent cause, replace it with a new card.
Note When you replace a card with an identical type of card, you do not need to make any changes
to the database.
