2.9 1:N Low-Density to 1:N High-Density Upgrade
2.9 1:N Low-Density to 1:N High-Density Upgrade
(Cisco ONS 15454)
The following procedure describes the upgrade of DS1 electrical cards to DS1/E1-56 high-density cards
using TL1. This procedure can be performed only when logged in as a Superuser.
Note • Protect cards must be upgraded before working cards because working cards cannot have more
capabilities than their protect card.
• 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 on the A side 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.
• The following limitations apply when upgrading low-density electrical cards to high-density
electrical cards:
– The protect card must be in a protection group.
– The protect card must not protect any low-density electrical cards on Slots 4, 5 or 6 if on the A
Side of the shelf and Slots 12, 13 or 14 if on the B Side of the shelf.
• Perform this procedure on low-density cards that are already in 1:N protection.
Step 1 On the protect card, change the card type from low-density to high-density:
Input Format:
CHG-EQPT:[<TID>]:<AID>:<CTAG>::<NEW_EQPT_TYPE>;
Input Example:
CHG-EQPT::SLOT-15:123::DS1-E1-56;
Step 2 Physically remove the low-density protect card and insert the high-density protect card.
Step 3 Switch the traffic from the working card to the protect card:
Input Format:
SW-TOPROTN-EQPT:[<TID>]:<AID>:<CTAG>::[<MODE>],[<DIRN>];
Input Example:
SW-TOPROTN-EQPT::SLOT-16:123::FRCD,SLOT-15,BTH;
Step 4 On the working card, change the card type from low-density to high-density:
Input Format:
CHG-EQPT:[<TID>]:<AID>:<CTAG>::<NEW_EQPT_TYPE>;
Input Example:
CHG-EQPT::SLOT-16:123::DS1-E1-56;
Step 5 Physically remove the working low-density card and insert the high-density card.
