DLP-D177 Convert DS3i-N-12 Cards From 1:1 to 1:N Protection
Note
This procedure assumes that DS3i-N-12 cards are installed in Slots 1 to 6 and/or Slots 12 to 17. The
DS3i-N-12 cards in Slots 3 and 15 are the protect cards. Each protect card protects the other DS3i-N-12
cards in that half of the shelf. The ONS 15454 SDH must run CTC Software R4.0 or later.
Step 1
In node view, click the
Maintenance > Protection
tabs.
Step 2
Click the protection group that contains Slot 3 or Slot 15 (where you will install the DS3i-N-12 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 and not Working/Active. If the protect slot status is
Working/Active, use the following steps to 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
Repeat Steps
and
for each protection group that you need to convert.
Step 5
Verify that no standing alarms exist for any of the DS3i-N-12 cards you are converting. If alarms exist
and you have difficulty clearing them, contact your next level of support.
Step 6
Click the
Provisioning > Protection
tabs.
Step 7
Click the 1:1 protection group that contains the cards that you will move into the new protection group.
Step 8
Click
Delete
.
Step 9
When the confirmation dialog box appears, click
Yes
.
Note
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. Therefore,
complete this procedure as soon as possible.
Step 10
If you are deleting more than one protection group, repeat Steps
through
for each group.
Step 11
Physically insert a DS3i-N-12 card into the same slot.
Step 12
Verify that the card boots up properly.
Step 13
Click the
Inventory
tab and verify that the new card appears as a DS3i-N-12 card.
Step 14
Click the
Provisioning > Protection
tabs.
Purpose
This task converts DS3i-N-12 cards from 1:1 protection to 1:N protection.
