DLP-A553 Upgrade Low-Density Electrical Cards in a 1:N Configuration to High-Density Electrical Cards
DLP-A553 Upgrade Low-Density Electrical Cards in a 1:N Configuration to
High-Density Electrical Cards
Caution Protect cards must be upgraded before working cards because working cards cannot have more
capabilities than their protect card.
Note You cannot upgrade electrical cards from low-density to high-density if the low-density electrical cards
are installed in Slots 4, 5, or 6 (or 12, 13, or 14 on the B side of the shelf). Only cards in Slots 1, 2, 16,
and 17 can be upgraded to high-density electrical cards.
Note This procedure describes an upgrade of Slots 1, 2, and 3 (15, 16, and 17) to high-density electrical cards.
However, you can have any combination of low-density (12-port) electrical cards and high-density cards
in Slots 1 and 2 (16 and 17) after you upgrade the protect card (Slot 3 or 15) to a high-density electrical
card.
Note During the upgrade some minor alarms and conditions appear and then clear on their own; however, there
should be no Service-Affecting (SA, Major, or Critical) alarms if you are upgrading protected cards.
(Upgrading an unprotected card can be service affecting.) If any service-affecting alarms occur, Cisco
recommends backing out of the procedure.
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.
Step 1 Determine which low-density card(s) (DS-1, DS-3, DS-3E) you want to upgrade to high-density,
according to slot limitations.
The following limitations apply if you are upgrading a low-density protect card:
• The protect card must be in a protection group.
Purpose This task upgrades low-density electrical cards in a 1:N protection
scheme (where N = 1 or 2) to high-density electrical cards (the
DS3/EC1-48 card). Low-density cards are defined any of the following:
DS-1, 12-port DS-3, and 12-port EC-1).
Tools/Equipment DS3/EC1-48 cards
High-density shelf assembly (15454-SA-HD)
High-density EIA (MiniBNC, UBIC-V, UBIC-H) installed
