Note
This task assumes that DS3-12E cards are installed in Slots 1 to 6 and/or Slots 12 to 17. The DS3-12E
cards in Slots 3 or 15, which are the protection slots, will be replaced with DS3N-12E cards.

In node view, click the
Maintenance > Protection
tab.
Step 2
Click the protection group containing Slot 3 or Slot 15 (where you will install the DS3N-12E card).
Step 3
Make sure the slot you are upgrading is not carrying working traffic. In the Selected Group list, the
protect slot must say Protect/Standby as shown

protect slot status is Protect/Active, switch traffic to the working card:
a.
Under Selected Group, click the protect card.
b.
Next to Switch Commands, click
Switch
.
The working slot should change to Working/Active and the protect slot should change to
Protect/Standby. If they fail to change, do not continue. Troubleshoot the working card and slot to
determine why the card cannot carry working traffic.
Step 4

Deleting the 1:1 protection groups will not disrupt service. However, no protection bandwidth
exists for the working circuits until the 1:N protection procedure is completed. Do not delay
when completing this procedure.
Step 10
If you are deleting more than one DS-3 1:1 protection group, repeat Steps
through
for each group
that you want to include in a 1:N group.
Step 11
Physically remove the protect DS3-12E card from Slot 3 or Slot 15. This raises an improper removal
alarm.
Step 12
In node view, right-click the slot that held the removed card and choose
Delete
from the shortcut menu.
Wait for the card to disappear from the node view.
Step 13
Physically insert a DS3N-12E card into the same slot.
