DLP-A293 Perform a Manual Span Upgrade on a Two-Fiber BLSR
Step 8
SNMP settings are now modified. To view SNMP information for each node, highlight the node IP
address in the Trap Destinations area of the Trap Destinations screen. Confirm that the changes appear;
if not repeat the task.
Step 9
Return to your originating procedure (NTP).
DLP-A293 Perform a Manual Span Upgrade on a Two-Fiber BLSR
Warning
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
circuitry could constitute an energy hazard.
Statement 206
Caution
Do not perform any other maintenance operations or add any circuits during a span upgrade.
Note
All spans connecting the nodes in a BLSR must be upgraded before the bandwidth is available.
Note
BLSR protection channel access (PCA) circuits, if present, will remain in their existing STSs. Therefore,
they will be located on the working path of the upgraded span and will have full BLSR protection. To
route PCA circuits on protection channels in the upgraded span, delete and recreate the circuits after the
span upgrade. For example, if you upgrade an OC-48 span to an OC-192, PCA circuits on the protection
STSs (STSs 25 to 48) in the OC-48 BLSR will remain in their existing STSs (STSs 25 to 48) which are
working, protected STSs in the OC-192 BLSR. Deleting and recreating the OC-48 PCA circuits moves
the circuits to STSs 96 to 192 in the OC-192 BLSR. To delete circuits, see the
Delete Overhead Circuits” procedure on page 9-4
. To create circuits, see
Chapter 6, “Create Circuits and
Step 1
Apply a Force switch to both span endpoints (nodes) on the span that you will upgrade first. See the
“DLP-A303 Initiate a BLSR Force Ring Switch” task on page 20-3
.
Step 2
Remove the fiber from both endpoints and ensure that traffic is still running.
Step 3
Remove the OC-N cards from both endpoints.
Purpose
This task upgrades a two-fiber BLSR span to a higher OC-N rate. To
downgrade a span, repeat this task but choose a lower-rate card in
.
Tools/Equipment
Higher-rate cards
Compatible hardware necessary for the upgrade
Attenuators might be needed for some applications
