DLP- D176 Convert E1-N-14 Cards From 1:1 to 1:N Protection
Step 2 Click the protection group that contains Slot 3 or Slot 15 (where you will install the protect E1-N-14
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 and not Working/Active. If the protect slot status is
Working/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 do not change, do not continue. Troubleshoot the working card and slot to
determine why the card cannot carry working traffic.
Step 4 Repeat Steps 1 through 3 for each protection group that you need to convert.
Step 5 Verify that no standing alarms exist for any of the E1-N-14 cards that 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 box appears, click Yes .
Note Deleting the 1:1 protection group does not disrupt service. However, no protection bandwidth
exists for the working circuits until you complete the 1:N protection procedure. Therefore,
complete this procedure as quickly as possible.
Step 10 If needed, repeat Steps 7 through 9 for other protection groups.
Step 11 Physically insert an E1-N-14 card into the protection slot (Slot 3 or Slot 15).
Step 12 Verify that the card boots up properly.
Step 13 Click the Inventory tab and verify that the new card appears as an E1-N-14.
Step 14 Click the Provisioning > Protection tabs.
Step 15 Click Create.
Step 16 Type a name for the protection group in the Name field (optional).
Step 17 From the Type drop-down list, choose 1:N (card).
Step 18 From the Protect Card drop-down list, choose the E1-N-14 card. Verify that the correct E1-N-14 card
appears in the Protect Card field.
Step 19 In the Available Cards list, highlight the cards that you want in the protection group. Click the arrow
(>>) tab to move the cards to the Working Cards list.
Step 20 If necessary, set a new reversion time in the Reversion time drop-down list.
Note 1:N protection groups are always revertive.
Step 21 Click OK. The protection group appears in the Protection Groups list on the Protection subtab.
Step 22 Return to your originating procedure (NTP).
