Chapter 2 Alarm Troubleshooting
Alarm Procedures
Caution Do not remove a card during a card reboot. If CTC begins to reboot a card before you remove the card,
allow the card to finish rebooting. After the card reboots, delete the card in CTC again and physically
remove the card before it begins to reboot.
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.
Note CTC gives the user approximately 15 seconds to physically remove the card before CTC begins a card
reboot.
Procedure: Clear the IMPROPRMVL Alarm
Step 1 In node view, right-click the card reporting the IMPROPRMVL.
Step 2 Choose Delete from the shortcut menu.
Note CTC does not allow you to delete the reporting card if the card is in service, has a circuit mapped
to it, is paired in a working protection scheme, has DCC enabled, or is used as a timing reference.

a. Click View > Go to Previous View to return to the node view.
