DLP- D247 Change an STM-N Card
Step 6 Repeat Steps 1 through 5 for other nodes, as necessary.
Step 7 Return to your originating procedure (NTP).
DLP-D247 Change an STM-N Card
Caution Physically removing an STM-N card can cause a loss of working traffic or a protection switch. See
Chapter 12, “Upgrade Cards and Spans” for information on upgrading traffic to a higher speed.
Note You can replace a multiport card with a card with a smaller number of ports only if the new card has the
same line rate as the multiport card. (The MRC-12 card can be replaced with either a single-port STM-4
card or a single-port STM-16 card.)
Step 1 If the card is the active card in a 1+1 protection group, switch traffic away from the card:
a. Log into a node on the network. If you are already logged in, go to Step b.
b. Display the CTC node (login) view.
c. Click the Maintenance > Protection tabs.
d. Double-click the protection group that contains the reporting card.
e. Click the active card of the selected group.
f. Click Switch and Yes in the Confirmation dialog box.
Step 2 In CTC, right-click the card that you want to remove and choose Change Card.
Step 3 From the Change Card drop-down list, choose the card type and click OK. An MEA alarm appears until
you replace the card.
Step 4 Physically remove the card:
a. Open the card latches/ejectors.
b. Use the latches/ejectors to pull the card forward and away from the shelf.
Purpose This task changes an STM-N card while maintaining existing provisioning,
including DCCs/generic communications channels (GCCs), circuits,
protection, timing, and rings. This task is intended to be used when you are
replacing a card with a card of identical type and line rate, when a slot is
preprovisioned and you want to change the optical speed of the card, or
when you have backed out of an automatic span upgrade.
