DLP-A176 Convert DS1-14 Cards From 1:1 to 1:N Protection
DLP-A176 Convert DS1-14 Cards From 1:1 to 1:N Protection
Note
This procedure assumes DS1-14 cards are installed in Slots 1 through 6 and/or Slots 12 through 17. The
DS1-14 cards in Slots 3 and 15, which are the protection slots, will be replaced with DS1N-14 cards.
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 DS1N-14 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 (shown
) and not Protect/Active. If the
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 do not change, do not continue. Troubleshoot the working card and slot to
determine why the card cannot carry working traffic.
Step 4
Repeat Steps
through
for each protection group that you need to convert.
Step 5
Click the
Alarms
tab to verify that no standing alarms exist for any of the DS1-14 cards that 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 group does not disrupt service. However, no protection bandwidth
exists for the working circuits until you complete the 1:N protection procedure. Therefore,
complete this procedure as quickly as possible.
Step 10
If needed, repeat Steps
for other DS-1 1:1 protection groups that you want to include in a 1:N
group.
Step 11
Physically remove the DS1-14 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 select
Delete
from the shortcut menu.
Wait for the card to disappear from node view.
Purpose
This task converts DS1-14 cards in a 1:1 protection scheme to 1:N
protection. A 1:N protection group can protect a maximum of five working
cards.
