Security Level
Protect cards must be upgraded before working cards because working cards cannot have more
Caution
capabilities than their protect card.
You cannot upgrade electrical cards from low-density to high-density if the low-density electrical cards
Note
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.
This procedure describes an upgrade of Slots 1, 2, and 3 (15, 16, and 17) to high-density electrical cards.
Note
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.
During the upgrade some minor alarms and conditions appear and then clear on their own; however, there
Note
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.
You cannot have any DS-1 cards installed on the same side of the shelf as the DS3/EC1-48 card when
Note
you finish the low-density to high-density upgrade.
Determine which low-density card(s) (DS-1, DS-3, DS-3E) you want to upgrade to high-density,
Step 1
according to slot limitations.
The following limitations apply if you are upgrading a low-density protect card:

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).
DS3/EC1-48 cards
