NTP-A308 Upgrade In-Service Low-Density Electrical Cards to High-Density Electrical Cards
Note For 1:N protection groups, the protect card is installed in Slot 3 on the A side of the shelf and
Slot 15 on the B side. For 1:1 protect groups, working and protect cards can be installed in any
traffic slot.
The following limitations apply if you are upgrading a low-density protect card:
• The protect card must be in a protection group.
• The protect card must not protect any low-density electrical cards in Slots 4, 5, or 6 on the A side
of the shelf (Slots 12, 13, or 14 on the B side).
• 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 DS3XM-12 card can protect a DS3XM-6 or DS3XM-12 card on the other side of the shelf, but
the protected card must be in portless mode.
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).
Step 4 In node view, double-click the current protect card. The card view appears.
Step 5 Make sure the current protect card is not active:

Step 7 Physically remove the card:
a. Open the card ejectors.
