Step 14 Physically insert a DS1N-14 card into the same slot.
Step 15 Verify that the card boots up properly.
Step 16 Click the Inventory tab and verify that the new card appears as a DS1N-14.
Step 17 Click the Provisioning > Protection tabs.
Step 18 Click Create. The Create Protection Group dialog opens with the protect card in the Protect Card field
and the available cards in the Available Cards field.
Step 19 Type a name for the protection group in the Name field (optional).
Step 20 Click Type and choose 1:N (card) from the pull-down menu.
Step 21 Verify that the DS1N-14 card appears in the Protect Card field.

tab to move the cards to the Working Cards list.
Step 23 Click OK. The protection group appears in the Protection Groups list on the Protection subtab.
Procedure: Convert DS3-12 Cards From 1:1 to 1:N Protection
Note This procedure assumes that DS3-12 cards are installed in Slots 1 - 6 and/or Slots 12 - 17. The
DS3-12 cards in Slots 3 and 15, which are the protection slots, will be replaced with DS3N-12 cards.
The ONS 15454 must run CTC Release 2.0 or later. The procedure also requires at least one DS3N-12
card and a protection group with DS3-12 cards.
Step 1 In node view, click the Maintenance > Protection tabs.
Step 2 Click the protection group containing Slot 13 or Slot 15 (where you will install the DS3N-12 card).
Step 3 Make sure the slot you are upgrading is not carrying working traffic. In the Selected Group list, the
protect slot must say Protect/Standby as shown in Figure 7-8 on page 7-32, and not Protect/Active. If the
protect slot status is Protect/Active, use the following steps to switch traffic to the working card:
a. Under Selected Group, click the protect card.
b. Next to Switch Commands, click Switch.
The working slot should change to Working/Active and the protect slot should change to
Protect/Standby. If they fail to change, do not continue. Troubleshoot the working card and slot to
determine why the card cannot carry working traffic.
c. Next to Switch Commands, click Clear.
Step 4 Repeat Steps 2 and 3 for each protection group that you need to convert.
Step 5 Verify that no standing alarms exist for any of the DS3-12 cards you are converting. If alarms exist and
you have difficulty clearing them, contact your next level of support.
Step 6 Click the Provisioning > Protection tabs.
Step 7 Click the 1:1 protection group that contains the cards that you will move into the new protection group.
Step 8 Click Delete.
Step 9 When the confirmation dialog displays, click Yes.
