DLP- A554 Upgrade EC-1 Cards in a 1:1 Configuration to DS3/EC1-48 Cards
Slot 1 contains the protect card if you are working on the A side of the shelf, and Slot 17 contains the
protect card if you are working on the B side of the shelf.
Step5 Make sure the current protect card is not active:
a. In card view, click the Maintenance > Protection tabs.
b. Select the protection group where the protect card resides.
Step6 If the card status is Protect/Active, perform a switch so that the protect card becomes standby:
a. Click Switch.
b. Click Yes in the confirmation dialog box.
Step7 Physically insert the new high-density electrical card into the new 1:N protect slot (Slot 3 for the A-Side
and Slot 15 for the B-Side). Be sure to remove the plastic protective covers on rear of the card before
installing the card.
a. Open the ejectors on the card.
b. Slide the card into the slot along the guide rails.
c. Close the ejectors.
For more information about LED behavior during the high-density card boot-up, see theNTP-A17 Install
the Electrical Cards, page 2-10. Allow the card to completely boot up before proceeding.
Step8 Delete the 1:1 EC1-12 low density protection group. See the “DLP-A155 Delete a Protection Group”
task on page 18-23.
a. Open the card ejectors.
b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the
upgrade is complete.
Step9 Create a 1:N protection group for the EC1-12 cards and the new DS3/EC1-48 card. See the“NTP-A324
Create Protection Groups” task on page4-11.
Note Make sure that the new protection group is 1:N and not 1:1. If you upgrading the A side of the
shelf, make sure the protect card is in Slot 3 and the working cards are Slots 1 and 2. If you are
upgrading the B side of the shelf, make sure the protect card is in Slot 15 and the working cards
are in Slots 16 and 17.
Step10 Because the low-density card is now active, switch traffic away from the low-density card in Slot 1 if
you are working on the A side, or Slot 17 if you are working on the B side:
a. In node view, double-click the card in Slot 1/Slot 17.
b. Click the Maintenance > Protection tabs.
c. Double-click the protection group that contains the working card in Slot 1/Slot 17.
d. Click the card in Slot 1/Slot 17.
e. Click Switch and Yes in the Confirmation dialog box.
Step11 Physically remove the low-density card in Slot 1/Slot 17:
a. Open the card ejectors.
b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the
upgrade is complete.
