Chapter 12 Upgrade Cards and Spans
NTP-A94 Upgrade OC-N Cards and Spans Automatically
Caution You cannot upgrade a four-port OC-12 span. If the ring contains any OC12-4 cards and you need to
upgrade all the spans in the ring, you will need to downgrade the OC12-4 card to a single-port OC-12
card (which is only possible if one port on the OC12-4 card is being used).
Step 2 Complete the “DLP-A60 Log into CTC” task on page 17-66. If you are already logged in, continue with
Step 3.
Note The Span Upgrade option will only be visible and available if the hardware necessary for the
upgrade is present; for example, no upgrade is possible from an OC-48 span unless XC10G cards
are installed in the nodes at both ends of the span.
According to local site practice, complete the “NTP-A108 Back Up the Database” procedure on
page 15-4.
Step 3 Ensure that no alarms or abnormal conditions (regardless of severity), including LOS, LOF, AIS-L, SF,
SD, and FORCED-REQ-RING are present. See the “DLP-A298 Check the Network for Alarms and
Conditions” task on page 19-63 for instructions.
Note During the upgrade/downgrade some minor alarms and conditions display and then clear
automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than
BLSROSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any
other service-affecting alarms occur, Cisco recommends backing out of the procedure.
A four-node BLSR can take up to five minutes to clear all of the BLSROSYNC alarms. Allow
extra time for a large BLSR to clear all of the BLSROSYNC alarms.
Step 4 In network view, right-click the span you want to upgrade.
Step 5 Choose Span Upgrade from the drop-down list.
Step 6 The first Span Upgrade dialog box appears (Figure 12-1). Follow the instructions on the dialog box and
the wizard will lead you through the rest of the span upgrade.
Note The Back button is only enabled on Step 2 of the wizard; because you cannot back out of an
upgrade via the wizard, close the wizard and initiate the manual procedure if you need to back
out of the upgrade at any point beyond Step 2.
