Chapter 1 Alarm Troubleshooting
1.3.63 IMPROPRMVL
• Critical, Service-affecting
A card was physically removed from its slot before the card was deleted in CTC. The card does not need
to be in-service to cause this alarm, it only needs to be recognized by CTC and the TCC+ card. This
alarm does not appear if you delete the card from CTC before you physically remove the card from the
node.
Note CTC gives the user approximately 15 seconds to physically remove the card before the CTC begins
a card reboot.
Caution Do not pull 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 15454.
Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf
assembly.
