DLP- A554 Upgrade EC-1 Cards in a 1:1 Configuration to DS3/EC1-48 Cards
DLP-A554 Upgrade EC-1 Cards in a 1:1 Configuration to DS3/EC1-48 Cards
Note You cannot have any DS-1 cards installed on the same side of the shelf as the DS3/EC1-48 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 cardcan cause a traffic
outage of up to 50 ms.
Step1 Complete the DLP-A60 Log into CTC, page 17-69. 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) you want to upgrade to high-density, according to slot limitations.
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:
•If you are upgrading an EC1-12 card in a 1:1 protection group to a DS3/EC1-48 card, the EC1-12
cards must be in either Slots 1 and 2 or 16 and 17.
•If you are upgrading EC1-12 cards in a 1:1 protection group to a DS3/EC1-48 card, Slot 3 needs to
be unoccupied if upgrading on the A-Side, and Slot 15 needs to be unoccupied if upgrading on the
B-Side.
Step4 In node view, double-click the current protect card. The card view appears.
Purpose This task upgrades low-density electrical cards in a 1:N protection
scheme (where N = 1 or 2) to high-density electrical cards
(DS3/EC1-48, DS1/E1-56, and DS3XM-12 cards). Low-density cards
are defined as DS-1 and DS3-12. This procedure also upgrades
low-density electrical cards (DS3XM-6 cards) in a 1:1 protection
scheme to high-density electrical cards (DS3XM-12 cards).
