DLP- A553 Upgrade DS1 or DS3-12 Cards in a 1:N or 1:1 Configuration to High-Density Electrical Cards
•For 1:N protection groups where N = 2: On the A side, the protect card cannot be upgraded if any
electrical cards are installed or preprovisioned in Slots 4, 5, or 6 (or Slots 12, 13, or 14 on the B side).
•For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and
it protects a low-density card in Slot 1, the protect card cannot be upgraded if Slot 5 or 6 has an
electrical card installed or preprovisioned. For the B side, if the protect card is installed in Slot 15
and it protects a low-density card in Slot 17, the protect card cannot be upgraded if Slot 12 or 13 has
an electrical card installed or preprovisioned.
•For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and
it protects a low-density card in Slot 2, the protect card cannot be upgraded if an electrical card is
installed or preprovisioned in Slot 4. On the B side, if the protect card is installed in Slot 15 and it
protects a low-density card in Slot 16, the protect card cannot be upgraded if an electrical card is
installed or preprovisioned in Slot 14.
The following limitations apply to upgrading a working card after you have upgraded the protect card:
•A working card in Slot 1 on the A side (Slot 17 on the B side) cannot be upgraded if an electrical
card is installed or preprovisioned in Slot 5 or 6 (Slot 12 or 13 on the B side).
•A working card in Slot 2 on the A side (Slot 16 on the B side) cannot be upgraded if an electrical
card is installed or preprovisioned in Slot 4 (Slot 14 on the B side).
Step4 In node view, double-click the current protect card. The card view appears.
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 remove the card:
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.
Step8 Right-click the Protect/Standby slot and change the low-density card to the high-density card:
a. Choose Change Card from the drop-down list.
b. Choose the new high-density card type from the Change to drop-down list.
c. Click OK.
Step9 Physically insert the new high-density electrical card into the protect slot. 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.
Wait for the IMPROPRMVL alarm to clear and the card to become standby. For more information about
LED behavior during the high-density card boot-up, see the "NTP-A17 Install the Electrical Cards"
procedure on page 2-9.
Step10 Because the low-density working card is now active, switch traffic away from the low-density card:
a. In node view, double-click the slot where the low-density card is installed.
