(PPM) alarm.
The working port raises the CR,IMPROPRMVL,SA alarm and the protected port raises the
MN,IMPROPRMVL,NSA alarm. The severity on the client ports is changed according to the protection
switch state.
• Electrical issues such as short circuit or failure of DC-DC conversion.

DETAILED STEPS
Step 1 In node view (single-shelf mode) or shelf view (multishelf mode), right-click the card reporting the IMPROPRMVL.
Step 2 Choose Delete from the shortcut menu.
CTC does not allow you to delete the reporting card if the card is in service, does have circuits mapped to it,
is paired in a working protection scheme, has DCC enabled, or is used as a timing reference.
Note
Step 3 If any ports on the card are in service, place them out of service (OOS,MT):
Before placing a port out of service (OOS,MT) or OOS,DSBLD (or Locked,disabled), ensure that no live traffic
is present.
Caution
a) In node view (single-shelf mode) or shelf view (multishelf mode), double-click the reporting card to open the card
view.
b) Click the Provisioning > Line tabs.
c) Click the Admin State column of any in-service (IS) ports.
d) Choose OOS,MT (or Locked,maintenance) to take the ports out of service.
Step 4 If a circuit has been mapped to the card, complete the Delete a Circuit, on page 454 procedure.
Before deleting the circuit, ensure that the circuit does not carry live traffic.
Caution
Step 5 If the card is paired in a protection scheme, delete the protection group by completing the following steps:
a) Click View > Go to Previous View to return to node view (single-shelf mode) or shelf view (multishelf mode).
b) If you are already in node view (single-shelf mode) or shelf view (multishelf mode), click the Provisioning >
