May 2002
Chapter 1 Alarm Troubleshooting
Alarm Procedures
Step 4 If you prefer the card that physically occupies the slot, put the cursor over the provisioned card in CTC
and right-click to choose Delete Card.
The card that physically occupies the slot reboots, and CTC automatically provisions the card type into
that slot.
Note If the card is in service, has a circuit mapped to it, is paired in a working/protection scheme, has
DCC communications turned on, or is used as a timing reference, then CTC will not allow you
to delete the card.
Step 5 If the card is in service, take the facility out of service:
Caution Before taking the facility out of service, ensure that no live traffic exists on the facility.
a. Double-click the reporting card to display the card view.
b. Click the Provisioning tab.
c. Click the Status of any in-service ports.
d. Choose Out of Service to take the ports out of service.
Step 6 If a circuit has been mapped to the card, delete the circuit:
Caution Before deleting the circuit, ensure that no live traffic exists on the facility.
a. On the node view, click the Circuits tab.
b. Choose the applicable circuit (the one that connects to the reporting card).
c. Click Delete.
Step 7 If the card is paired in a protection scheme, delete the protection group:
a. Click the Provisioning > Protection tabs.
b. Choose the protection group of the reporting card.
c. Click Delete.
Step 8 Right-click the card reporting the MEA.
Step 9 Choose Delete.
1.5.49 MEA (FAN)
Critical, Service-affecting
The mismatch between entity/equipment type and provisioned attributes alarm is reported against the
fan tray when an older ONS 15454 SDH fan-tray assembly (FTA2) is used with certain cards that require
the newer fan-tray assembly (15454E-FTA-60V or 15454E-FTA-48V). The 10-Gbps-compatible shelf
assembly (15454E-SA-ETSI) and fan-tray assembly (15454E-FTA-60V or 15454E-FTA-48V) are
required with the ONS 15454 OC192 LR/STM64 LH 1550, E1000-2-G, E100T-G,
OC48 IR/STM16 SH AS 1310, or OC48 LR/STM16 AS 1550 cards.
