DLP- A553 Upgrade DS3XM-6 Cards in a 1:1 Configuration to High-Density DS3XM-12 Electrical Cards
Step16 Return to your originating procedure (NTP).
DLP-A553 Upgrade DS3XM-6 Cards in a 1:1 Configuration to High-Density DS3XM-12 Electrical Cards
Note You cannot have any DS-1 cards installed on the same side of the shelf as the DS3XM-12 card when you
finish the low-density to high-density upgrade.
Caution After upgrading a DS3XM-6 card to a DS3XM-12 card, the newly installed DS3XM-12 card will run in
STS-12 mode. To change the backplane throughput rate, make sure the card is out-of-service and not
carrying live traffic. Changing the backplane throughput rate on a in-service card can cause a traffic
outage of up to 50 ms.
Step1 Complete the "DLP-A60 Log into CTC" task on page 17-68. If you are already logged in, continue with
Step 2.
Step2 According to local site practice, complete the "NTP-A108 Back Up the Database" procedure on page
15-5.
Step3 Determine which low-density card(s) (DS3XM-6) you want to upgrade to high-density, according to slot
limitations.
Note For 1:1 protect groups, working and protect cards can be installed in any traffic slot. But both cards
should be placed adjacent to each other.
The following limitations apply if you are upgrading a low-density protect card:
•The protect card must be in a protection group.
•For 1:N protection groups where N = 1: If 1:1 is created on A side protect card cannot be upgraded
if an DS1 card is installed or preprovisioned in A side. If 1:1 is created On the B side the protect
card cannot be DS1 card is installed or preprovisioned in B side
Purpose This task upgrades low-density electrical cards in a 1:1 protection
scheme to high-density electrical cards (DS3XM-12 cards). This
procedure upgrades low-density DS3XM-6 cards in a 1:1 protection
scheme to high-density DS3XM-12 cards.
Tools/Equipment DS3XM-12 card(s), as needed.
Upgrade of DS3XM-6 to DS3XM-12 does not require a High-density
shelf assembly. The upgrade can be performed on low-density shelf
assembly as well.
